My call with Lara Hill was great. Lara is intelligent and even in the short time we had explained what might be causing some of the things I’m dealing with, and she explained a clear plan of action moving forward. I didn’t feel rushed, and she allowed me to explain everything I needed to.

Verified Patient

You have a treasure with Miya. She is very knowledgeable about cv risk factors, your protocol and services offered! Not only that but she is a pleasant and positive representative for your organization. I will certainly reach out again in the future as the need arises. Thank you. Sara Capece

Dr. Wolfson, thank you for offering this free discovery. Ali is great, we went through some of my recent blood work test, and she recommends we need to get a few more to get to the root cause of my abnormal blood test.

Verified Patient

My discovery call was excellent. Angeline was knowledgeable, personable, and on top of things! When I read her follow-up email to me, I saw that she had jotted down all the details I mentioned to her. I am impressed! I just wish I could afford the solutions she has to offer. :/

Verified Patient

Coach Ashley Swanson was very helpful answering my questions even though my phone cut off several times. She was very kind and knowledgeable. Thanks for the free discovery call!

Verified Patient

Miya was fantastic! Gave me some great information and clearly outlined what the next steps should be.

Verified Patient

My discovery call was great. Ashley was receptive to my questions and a great listener. She answered all my questions to the best of her ability and when she didn’t know something (like if some supplements ship to Indonesia) she was honest about it and said she would ask her internal team if they could help. I look forward to receiving the review email and going forward from there.

Verified Patient

Miya was very sweet and helpful for my journey to learn how to correct my health problems. Her knowledge into the natural health world was a great learning curve for me. I feel so much better after speaking with her. I’m looking forward to my second opinion appointment. Thank you Dr. Wolfson for reaching out and helping people.

Verified Patient

Consultation with Ashley was great. I gave her a brief description of my digestive concerns and she gave recommendations instantly. The products suggested gave me confidence that I’m headed in the right direction. A peace of mind will also be a peaceful body, that’s key, that’s a start.

I’ve been incredibly frustrated with my traditional healthcare chain (Scripps, in San Diego, CA) options for a cardiologist. They only offer no answers to my questions and concerns, and changing to a different doctor who actually shared my values and priorities for my own health, was absolutely impossible. If you don’t stay in-step with traditional “pills and procedures” band-aid solutions, there’s nothing for you anywhere in that system (or the other healthcare chains in the San Diego area- I searched them all). But I want to find and cure the root cause, not just treat the symptoms with medication and potentially invasive procedures. Enter these amazing folks. In 20 minutes, I realized I have found a group of doctors who exactly share my values. They align perfectly with my desire to not use medication when natural solutions are available, my desired heart health path, as well as my overall health and nutrition paths. After so much frustration in searching for traditional doctors, I was pretty unsure and a little skeptical. “What’s their angle going to be?” I was surprised, impressed, and relieved I’d finally found exactly who I was looking for. If you’re looking for a better answer than “do these tests and procedures and take these pills” these folks are for you. I’m extremely happy I found them. I’ve found the cardiologist team I’ve been looking for.

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.

What is the timeline to receive an online second opinion?

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. 

Is my medical and payment information secure?

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). All financial transactions are processed by Natural Heart Doctor securely using industry standard payment processing tools.

I would rather visit Natural Heart Doctor for an in-person appointment. What should I do next?

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

Yes, we’re happy to help you on an extended basis. Our clinician can discuss options with you when presenting our second opinion summary.
