What do you like to do in your free time?

Once they have hope that their body can heal, they can tackle root cause issues, put the work in, and finally get well.

Dr. Jack Wolfson DO, FACC

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.

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.

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.

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!

Mike B. Verified Patient

Outstanding

Dr. Jack Wolfson’s webinar on “High Blood Pressure: Get Off the Meds Safely” was outstanding!

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!

Steve R. Verified Patient

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.

Daniel K. Verified Patient

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.

appreciate the time

I appreciate the time allowed to me to ask all my questions and the advice provided.

Nancy R. Verified Patient

Healthier Heart

I choose Dr. Kneller because of his background and willingness to embrace natural healing modalities, I am off my pharmaceuticals and use only natural products to manage my AFib. I still deal with chronic mold and lyme but am so very excited that my heart is healthier than it has been in a very long time. I applaud the natural heart facility for their commitment to healing the natural way.

Randy S. Verified Patient

He REALLY Listened

I learned a lot and felt Dr. Kneller REALLY listened. He listened enough to mention, I am told, that scotchbroom/scilla tincture prescribed by my ND, helps me avoid AFib, as it helps my wife avoid tachycardia. “Scotch broom or cytisus scoparius, is a weed that grows in the Pacific Northwest and its active constituents are quinolizidine alkaloids, particularly sparteine. It acts similarly to quinine and quinidine, though is overall much safer. It has been used for congestive heart failure and to help regulate heart rhythm and a-fib and v-fib and extrasystoles. Sparteine antagonizes potassium channels and to a lesser extent, sodium channels. It should be avoided with drugs that inhibit CYP 2D6 [cimetidine, fluoxetine, amiodarone].

Scilla is a lily plant that grows in the Mediterranean. Its active constituent is proscillaridin, which is a cardiac glocoside. Its actions are less than digitalis, although have shown to be effective in cases of arrhythmias and heart failure.” I am taking the Mag-5 and feel much better by doing so.

Carol G. Verified Patient

My AFib Journey

Three years into my AFIB journey it was helpful to speak with NHD’s EP, Dr Kneller. August 31, 2023, I had experienced a second failed ablation and was feeling quite discouraged and frustrated. I had newly begun the NHD AFib protocol prior to the second ablation. My regular cardiologist believed it was necessary due to a low EF. Ablation was complex and I was immediately placed on Tikosyn (stabilizes over 3 days in hospital).

Considering all that and loss of faith in my local doctor (who I like very much), the plan was to continue AFib supplements with new additions for six months, then discontinue the Tikosyn and see what happens. At that point, if AFib flares again into persistent, to seek another “second” opinion with the Cleveland Clinic. Considering my age, otherwise excellent health and commitment to wellness in all levels (ie, diet, exercise, meditation, stress management, supplementation…), Dr Kneller gave me confidence that the AFib could no longer be a problem. Which for me means either no recurrence or occasional that can be managed without medication.

NHD highly recommends testing. I’ve done most but not all. My home is receiving mold remediation next week. Even though I don’t have symptoms, probably the colon test is warranted. I will stop the Tikosyn when all of that is in place, by early summer. And will have another consultation with Dr. Kneller prior.

Michael P. Verified Patient

Feel At Ease

After having a previous cardiologists instruct me to get on a statin because their office policy was that everyone needs to have a LDL at 75. I refused the statin and then was threatened that if I didn’t change my ways, I wouldn’t be around in 5 years… nice guy huh? (it’s been 6 years so far) The next cardiologist was fine with my numbers for a while until I asked him to check my CAC score. Once he learned I had a risk with a 388, I was influenced to get a nuclear stress test. I guess that turned out questionable so immediately we are looking at angiogram with possible stents…yikes.

I had no symptoms and needed a second opinion so as to get cardiac clearance for an upcoming colonoscopy…

I learned about Natural Heart Doctor from an acquaintance in the Midwest who knew about Dr. Jack Wolfson. I looked up the place which was local and set up a second opinion appointment with Dr. James Kneller. I felt at ease with him and was able to have a conversation (not a one-sided monologue) and receive a better understanding of my heart situation. I’ve been working on my metabolic health with a keto/carnivore lifestyle and fully believe that I can get healthy by working with Dr. Kneller and the staff at Natural Heart Doctor. Thank you for being available and for thinking outside the heavily influenced Western Medicine machine. More people need to take control with knowledge and be their own health advocates.

Bryan M. Verified Patient

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.

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.

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!

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.

We do our best to schedule your second opinion as quickly as possible. Typically, it takes 5 to 7 business days after your information has been collected to receive your phone or video online second opinion.

What information do you need in advance of our call?

Our office will send you a short questionnaire to complete and return. We DO NOT need your complete medical records.

How many questions can I ask the expert during our call?

You may ask a maximum of five questions. This is to ensure that the expert has sufficient time to devote to each question. All questions must be finalized before your online meeting.

What should I expect to receive once my second opinion is complete?

You will receive a summary of our discussion along with our second opinion. The second opinion will be in written form. After you have reviewed the second opinion, a Natural Heart Doctor clinician will follow up with you by phone to address general medical questions about the information provided in the second opinion.

What if I have follow-up questions for the expert after I have reviewed my second opinion?

If you have a clarifying question about an expert’s response to one of the questions in your second opinion, and the Natural Heart Doctor clinician is unable to address it, then you may request a follow up session for an additional fee.

Natural Heart Doctor is strongly committed to protecting the privacy and security of all our patients. Our website meets all federal requirements for protecting personal health information under the Health Insurance Portability and Accountability Act (HIPAA).

Can I schedule a follow up appointment with the specialist who provided my online second opinion?
