      Derek W. Guillory, MD, our founder and Medical Director, earned his Bachelor of Science in Education at Baylor University in 1997, graduating Magna Cum Laude. In 2001, he graduated from the University of Texas Southwestern Medical Center in Dallas. He continued his medical training in Emergency Medicine at UT Southwestern Medical Center, graduating in 2004. He has been continuously Board Certified by the American Board of Emergency Medicine since 2005.

      He became one of the first Certified Functional Medicine Practitioners in Texas in 2015.

      Dr. Guillory has a passion for functional medicine that was born out of his own personal struggle with health concerns within conventional medicine that began before the age of 17. That passion has persisted and grown through years of medical training and through more than a decade in urban emergency departments treating critically-ill patients. Emergency patients often have severe, life-threatening illness, some of which, if addressed within a functional medicine model years or decades earlier, would have been preventable and sometimes reversible.

      He shares a common mindset among functional medicine practitioners—as well as among most of our patients—an insatiable curiosity for the often seemingly unanswerable question, “Why am I sick?”

      Dr. Guillory loves helping his clients find the answers to that question.
