ABOUT DR. SMIGIEL

Dr. Keith Smigiel is a leader in longevity, vitality, and regenerative medicine — helping patients not just live longer, but live stronger.

With decades of experience as both a Family Nurse Practitioner (FNP-C) and Doctor of Chiropractic (DC), he goes far beyond symptom management. He hunts down the real drivers of disease — mold toxicity, environmental toxins, and the hidden root causes behind cardiovascular issues, high blood pressure, and accelerated aging.

His regenerative toolkit includes PRP Therapy, Ozone, Neural Prolotherapy, and IV Infusions — advanced therapies that activate the body’s own ability to heal, repair damaged tissue, and restore youthful function at the cellular level.

The result: patients don’t just feel better. They rebuild, regenerate, and reclaim the energy and vitality they thought they’d lost.

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.
