Get a Second Opinion From Dr. Lattanza When:

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.

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!

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.

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.
