Testimonials

Dr. Jack Wolfson DO, FACC

Forever Be Grateful

11 years ago today, my husband had a widowmaker followed by triple bypass surgery. 8 days later we slowly walked into Dr. Jack Wolfson’s office for the beginning of our healing journey. We will forever be grateful to this great doctor for all he has done, not only for us, but for others around the globe.  The information he and his team provide for all is priceless. God bless you all today and here’s to great health!

HE IS A HEALER

Dr Wolfson was the first doctor after a major, serious heart even to a) know about the diagnosis and had experience in it and b) offer hope of healing and normalcy that the medical system couldn’t offer. He alone was the catapult to me believing I could live normal life again. I’m always on the journey of improvement, but Dr Wolfson listened, encouraged and gave me guidance and a map to get to where I wanted to be. He’s a healer, holistically, and a key role in my healing. Highly recommend him and his team

Lisbett C. Verified Patient

Off the Meds

My husband had a heart attack just over 2 years ago. We knew we didn’t want to get on a treadmill of endless drugs and interventions. In my research for better answers for him I found Dr. Jack Wolfson, a board certified cardiologist that has embraced a kinder, saner, more life enhancing approach to treatment and healing. Through his many webinars, courses, feedback, and articles, we felt empowered to make healthier choices moving forward. We also use many of his suggested supplements. My 75 year young husband is doing great! He is now totally off any allopathic meds. We are very grateful.

Patient Review

I'm AFib Free

Jack Wolfson thank you for all you do! 1 year following your protocol and I’m afib free! 🎉

Absolutely Terrific

Dr. Wolfson and his staff are absolutely terrific. They are always friendly and willing to help. I feel confident I am in good hands. I have learned so much not only as it relates to my heart but my overall health as well since our paths crossed a year ago.

Well Done

It is refreshing to know that here is a Cardiologist who understands that lifestyle choices and habits can change the course of one’s path of health and wellness. Not easy to make lifestyle changes, so many find it much easier to pop prescription drugs and not take responsibility for one’s health. Thank you for being the change, well done!

Danielle D. Verified Patient

Super Impressed

The Natural Heart Doctor is the true definition of good health care. I had searched many years looking for a board-certified, naturopathic cardiologist. I am so grateful I found Dr Jack Wolfson and his team. I was able to come off of my cardiac medication, leave behind the side effects and improve my heart function using his supplements. Not only am I feeling better, but my traditional cardiologists is super impressed by the results on my latest echocardiogram. Making an appointment with Dr. Jack Wolfson was one of the best decisions of my life. Don’t wait, book your appointment today!

Outstanding

Dr. Jack Wolfson’s webinar on “High Blood Pressure: Get Off the Meds Safely” was outstanding! Both my wife Deb and I have been using Dr. Wolfson’s heart healthy protocols, with heart focused supplements and lifestyle to improve our health. Deb’s most recent lab’s shown a great improvement in her heart health. I also use both the Daily Defense and Cardiology coffee routinely with goal to achieve the 100 year heart!

Better Lifestyle

I credit Dr. Wolfson and his staff for guiding me on a 2 year trip to better health and control of AFIB. Three attacks in the last 18 months and no visits to the emergency room. Better health from a better lifestyle that includes chiropractic care, diet, and elimination of toxins.

Awesome

After 9 years of off and on afib, about 10 cardioversions and 2 ablations, working with Dr Wolfson I was able to lose 30 # and get off all prescriptions by eating Keto/Paleo and taking their supplements. Their coaching programs are awesome.

highly recommend

At 75 I had the widowmaker heart attack. Under Dr. Wolfson’s care I have been able to restore my heart health and return to my job as an executive in a non-profit. Wolfson is passionate about educating people about how to have a healthy heart. When most cardiologists want to give you meds he takes a holistic approach with complete blood analysis, diet and environmental issues that affect our health. He designed a nutritional program to heal my overall health. I highly recommend him. 

Don L. Verified Patient

Off Pharmaceuticals

After extensive testing, Dr. Jack Wolfson developed an extensive plan for my future health. After three years, my health is much improved and I am off all pharmaceuticals. I highly recommend the Natural Heart Doctor.

Perfect Blood Pressure

I have the same story, widowmaker and 3x bypass than two months later with Dr. Wolfson. That was eight years ago. After bypass hospital sent me home with a bag of drugs and no hope. Today I take no meds and have perfect blood pressure because of Wolfson’s protocols and see their office only once a year and I feel amazing. 

Rod F. Verified Patient

GRATEFUL

I’ve been seeing Dr. Wolfson for several years now. His advice and expertise have completely changed my health and life for the better. I’ve also recommended his book, “The Paleo Cardiologist,” and his teachings to my loved ones, and they’ve experienced fantastic improvements too. It’s wonderful to have doctors like him and his wife who genuinely care about people and provide great natural healthcare options. They make the world a better place. Grateful.

Improved my health tremendously

Within the last few weeks we had a Zoom consultation after my recent blood draw.  This was the fourth comprehensive blood test in 2 years since joining your practice. Each time numbers have improved! I want to thank you for your excellent information and caring. Since finding you 2 years ago when I went off the statins (20 Mg Simvastatin) and blood pressure pharmaceutical (10 Mg Lisinopril). I have followed your supplemental plan recommendations, the Paleo diet and two 21 day challenges. I have improved my daily life / health tremendously. Previous to working with you I was not suffering from any negative symptoms or daily health concerns. Given having a heart attack with 2 stents 21 years ago, I always felt there was a better way than what I was told to do. I feel blessed that in all that time there were no negative reoccurrence. My history with the previous cardiologists was meeting annually for 30 minutes with the cardiologist (actually over 17 years I only met with him 4 times it was always his nurse). When he decided on 3 more pharmaceuticals I was determined to find a better way.  Your care program has given me a new way to go forward in great health. The three tenants of Live Well, Eat Well and Think Well are the basics of healthy living, living the best life you can. Amazingly, libido (although no previous problems) is substantial, dare I say, as if I was 25 again. I’ve noticed an increase in energy and mental clarity. I am a mechanical design engineer and the thought processes in “inventing” seems to come quicker and with less mental effort. Also feels as though my energy and stamina is better as evidenced by my workouts. In our conversation, I had mentioned I had spent well over $700+ monthly on the supplements from Natural Heart Doctor. I said that as a badge of honor.  As you mentioned “ how much is good heath worth?” I whole heartily agree! Just wanted to drop this note to you in appreciation for all you have done for me.

Extremely Helpful

I would like to say that Dr Wolfson has been extremely helpful to me with his webinars and great website. I have learned much from his website, including probably the most comprehensive information on AFIB that I have found in one spot. He has taken the fear out of the traditional method of treating heart issues and replaced it with empowering and effective solutions. Dr Wolfson does not underestimate the seriousness of heart problems either.

In fact, under Dr Wolfson’s guidance and his webinars as well, I have managed to get off my blood pressure meds ( after more than one year of afib issues! ). I was also able to replace the drug for afib with his suggestions and therefore, I no longer require the propafenone either. This has been a stressful 14 months of stress and anxiety to manage these conditions effectively.

 Angeline was also super helpful in the information process and the journey to this outcome. 

BTW, my blood pressure has never been better, in fact it is now excellent! 

My afib is really much much less than it was before. I’m not going to say it’s gone but I feel in control in managing it. It is reduced all in all at least 80% from where it was 14 months ago.

As a broker in the natural health field of supplements, I have directed many people to your website. There are many people, myself included, that want a more natural but effective solution to heart problems. The site is well laid out and has answers to many issues that affect so many people.

 Thanks to all of you at Natural Heart doctors for your help!

So Glad I Found
Dr. Wolfson

I found Dr. Wolfson on TT last year and I’m so glad I did. I’ve always been a fairly clean eater and careful of chemicals etc. I was a vegan and vegetarian for 20 years. Wrecked my health. I have thyroid issues and the generic meds made me start having heart palpitations (according to my pharmacists). I ended up on Atenolol.

Thanks to Dr. Wolfson and all of the posts on this group, I’ve been off my meds for 2 months. Can’t tell you how good I feel. I still have a few times when my heart rate is up a little but with diet I’ve have been able to manage. Now I’m working on adding in the supplements Dr. Wolfson recommends.

Also, I appreciate Dr. Wolfson warning about stevia. I have cut way back on my use and it has helped a lot. I am a work in progress and I appreciate all the help. I’m still learning and reading and working to get better. 62 years young

About Dr. Lauren Lattanza NMD, FACC

Dr. Lattanza Office Visit with Patient

As a Naturopathic Physician, I am trained to treat the whole person and get to the root cause of disease.

I went to Arizona State University where I graduated with a bachelor’s degree in psychology with a depth in physiology and minor in Spanish. After my undergraduate degree I was working on prerequisite classes towards medical school, which is when I came to learn that my values identified best with the principles of naturopathic medicine. I knew that I wanted to help patients identify the causes of disease and be able to offer treatments which would improve their health rather than simply treating symptoms.

I dedicated the next 4 years to the Southwest College of Naturopathic Medicine in Tempe, Arizona where I attained my Doctorate of Naturopathic Medicine. I served as Class President all 4 years, Board of Trustees – Student Trustee, spoke as the Club President for our branch of Toastmasters, and was voted by my peers and attending physicians to earn the Outstanding Leadership Award for the Class of 2020. Throughout medical school I took it upon myself to work alongside MDs, DOs, chiropractors, and functional medicine practitioners in addition to naturopathic physicians.

As a Spanish speaking student, I was able to volunteer with community clinics around Phoenix and provide free healthcare to low-income families. Due to this combined exposure, I came to find my passion in treating cardiometabolic and digestive disorders that are all too common, yet largely preventable. I took the opportunity to learn the broad spectrum of healthcare so I can ensure that I am able to provide my patients with the best options.

She's Fantastic

Since beginning this journey with cardiac family history and issues of my own. I originally started by reading the Paleo Cardiologist by Dr Jack Wolfson. After reading I was even more convinced that modern medicine was not the best answer for me at this point. My local cardiologist just continues to prescribe medications, stress test and now wants me to have angiogram and potential stenting. After speaking with a health coach, I booked a call with Dr Lattanza. She was fantastic, took the time to ask lots of questions, listened and truly understood my situation. She is helping formulate a plan for me moving forward aimed at getting off the pharmaceuticals and living my healthiest life.

Cindy B. Verified Patient

Huge Thank You

Dr. Lattanza is very knowledgeable in her field of medicine. She’s helped me through some very difficult times of finding out why I have palpitations. Giving me ways to deal with my health situations.  Anxiety being one.

I’ve done level two testing, and I have found out root causes of my Palpitations, and why I do go into AFib. I’m never afraid to talk with Dr. Lattanza, but always in fear to talk with my other heart doctor, or any of my other providers, as they push medications continuously.

I highly recommend Dr. Lattanza at Natural Heart Doctor and their coaches.  Huge thank you!

Rick T. Verified Patient

Super Impressed

Before my appointment with Dr. Latanza, I was experiencing chest pain and shortness of breath while exercising. After reviewing my history of heart issues, she directed me to a healthier diet and research-based supplementation. She assured me that a disciplined approach to eating well, and intermittent fasting could have good results in resolving my issues. Her assurances alone did wonders for me emotionally! 5 weeks later I’ve lost 15 lbs. and feel great! My blood pressure is coming down and blood sugar is under control. Couldn’t be more impressed!

Roger H. Verified Patient

Breath of Fresh Air

Dr Lattanza is a breath of fresh air.  We are both on the same page related to how my issues need handling.  Before meeting Dr Lattanza my cardio experience was statins , aspirin and potentially stints .

The former doctors had no solution for my LPA protein problem and sent me on my way . I was very frustrated and fortunately found Dr Wolfson and his team . Now I have hope and expect I will surpass the 100 year heart by at least 40%.

Leslie T. Verified Patient

The Whole Picture

My session was very helpful. My primary concern is lipid related, so I thought I would be better with one of the cardiologists. My NHD Health Coach suggested I meet with Dr. Lattanza based on the questions I have. Dr. Lattanza provided great insight and was able to “connect the dots” with other blood measures that may be impacting my lipid panel and overall health. I am very happy with my consultation with Dr. Lattanza because I feel she is addressing my “whole picture” and not just my cardiology concerns.

Shelley C. Verified Patient

I Feel So Calm

Had my annual checkup with Dr. Lattanza yesterday. I feel so calm after my appointment. She is kind and beautiful inside and out. It is so nice to work with a doctor who listens and works with me and my budget to get a plan that works for me. Thanks to the great staff, it has been two years of being off high blood pressure medicines.

Rick N. Verified Patient

Very Pleased

I was very pleased with the information I was given and the response to my questions. Dr. Lattanza is very well versed in her profession and was very easy to talk to and her willingness to listen was great. I enjoyed our conversation and felt that she is truly there to help me to achieve my goals. I’m looking forward to working with her in the future.

Thank you very much.

Kathleen M. Verified Patient

Thank You

Eighteen months ago, I was diagnosed with Afib. After a few visits to the hospital emergency room and a few visits to a cardiologist, I began to question if there might be a better solution. I was referred to the Natural Heart Doctor clinic by a member of my medical sharing facility. Working with Dr. Lattanza showed me how nutrition and lifestyle play such a vital role in heart and overall health. Even though I occasionally have symptoms of Afib, I have learned that there are things I can do to improve them and I have not had to go to the hospital emergency room in over five months. What surprised me most about this experience is that it is possible to make wiser nutrition and lifestyle choices that will heal and maintain the body that God gave me. Thank you, Dr. Lattanza!

Christina M. Verified Patient

Recommend Highly

I have been working with NHD — mostly Dr. Lattanza — for about 3 years for paroxysmal AFIB. My episodes had decreased dramatically in frequency, severity and length early on. Then came the breakrhrough. Once figuring out that I was taking too much thyroid med, and adjusting my dosage after years at the same dose as well as adding in their Thyrokick priduct, my AFIB episodes have STOPPED! The coaches always follow up after appointments with Dr. Lattanza too. Fantastic.

I take many of NHD’s recommended supplements, abide by their dietary suggestions, exercise regularly, and more. Recommend highly.

Brittany G. Verified Patient

Found the Cause

Working with Dr. Lattanza and Ali the health coach, the testing was so thorough and found the root cause of some issues that have been blown off by many doctors in the past. I am so grateful to have this proactive team help to educate me and guide me in making the changes needed to live a long and healthy life instead of waiting for issues to escalate into disease! Yes, it has a price tag, but everything of high quality/value typically does.

Great Appointment

The 20 minute appointment with Health Coach (Angeline) was great as well as the appointment with Dr. Lattanza. I am looking forward to working with Natural Heart Doctor. 

In Incredibly Good Hands!

Just had my first online appointment with Dr. Lattanza. She was very thorough in her questions and let me talk through all of my concerns as well. Bottom line – I am in incredibly good hands. She will send me the bloodwork that needs to be done to assess more deeply – especially to assess inflammation – the main issue. I know which supplements to take for now and feel like I finally have a plan! I am in very good hands! Cannot recommend NHD enough!

Great Depth of Knowledge

I am a current a patient of Dr. Lauren Lattanza. I have enjoyed her professionalism. She has a great depth of knowledge that she shares with me. She has provided me with so much good health information and is a great communicator. I highly recommend her for all of your health needs.

Thanks A Million

After suffering GI issues for years, Dr. Rainier was FINALLY able to recommend the dietary antigen test that shed light on my symptoms. Her vast knowledge of and expertise in GI issues and alternative treatments is life-saving. Dr. Rainier took time to explain all the results to me and prescribe a treatment plan individualized for my situation. Thanks a million Dr. Rainier!

Excellent Doctor

Dr Rainier is an excellent doctor, and gave me a lot of good advice and insight. I like her approach with natural methods being primary and pharmaceuticals being secondary or a bridge to wellness. Under normal circumstances, I would love to have her as my primary care physician. It’s sad that health insurance will not cover all or part of martial medicine, when the people who pursue it are among the healthiest people.

Private Verified Patient

So Grateful

So Grateful – From day one, Dr Rainier has been very supportive and insightful. She looked beyond skin deep to help identify some significant underlying concerns. Her insights have led to major lifestyle changes on my health journey, and the benefits are proving massive. When I faced a more acute injury, she was able to help take the information from the ER and help me determine how to align this with the overall lifestyle I have been working toward. The style of care, with provision of health coaching and doctor visits, has fit beautifully into our lifestyle.

Jennifer K. Verified Patient

A Huge Help

Working with Dr. Rainier has been a huge help. When we met last summer, I knew I was not healthy, and that help was definitely needed. Dr. Rainier helped to find the root cause (mold and hormones), and then offered support for lifestyle changes and how to move through the detoxification process. The journey has not always been easy, but Dr. Rainier and the team have been extremely supportive. I especially appreciate Dr. Rainier’s willingness to search for answers and to come up with custom treatment plans based on all the factors a patient is experiencing. The only downside is the change in the subscription options that happened last winter. Dr. Rainier and the team have been great! Thank you!

Great Results

On Feb 14th 2024 I had a complimentary Discovery Call with Angeline. After conventional doctors recommended pharmaceuticals and a pacemaker for my arrythmia issues, her recommendations made a lot more sense to me. I’ve been using Heart Beet, Vessel Support, Cardiolytes and Magne 5 and following the 100 Year Heart Diet with great results. Thank you Angeline Dr. Rainier and the Natural Heart Doctor Team!!

Amazing Experience

I’ve had an amazing experience working with Dr. Tonia Rainier over Zoom. She orders labs, recommends supplements, and provides truly personalized care. She’s helped me manage anxiety, guided me through genetic testing before starting BIEST hormone replacement (which improved my skin), and treated mold-related issues—leaving me with less inflammation and clearer thinking. Highly recommend Dr. Rainier and naturopathic medicine!
