“You have One Life, LIVE IT”
Mr. David Tiller is an El Paso, Texas native. He spent over eight years active duty in the US Navy before earning his bachelors degree in Sociology from the University of West Florida and then his graduate degree as a Physician Assistant from the University of Florida. After graduation he moved back to his hometown and began his practice of medicine.
After many years of practicing Emergency Medicine, Mr. Tiller wondered if there was a better way for his patients to live healthier lives. Heart attacks in 35 year olds, obesity, infertility, heart disease, depression, and a host of other problems that did not need to happen if patients were better educated about their own health and what they could do about it.
He realized that most primary and specialty doctors were unwilling, or simply did not know what to do. He began to spend much time studying Functional Medicine and attending coursework. In 2009 he began to help his patients optimize and take control of their own health.
He is a board certified through the National Commission of Certification of Physician Assistants, A Member of the American Academy of Anti-Aging Medicine, Academy of Preventive and Innovative Medicine and the American Academy of Physician Assistants.
