Our practice was founded after a long search to find a doctor that did things differently; the kind of doctor who listened, one who recognized each patient as more than a diagnosis and was willing to offer more than a prescription as treatment. Healthcare decisions are personal and should be based on a thorough discussion with a qualified medical professional who is your partner, who hears your concerns, identifies you as the unique sum of your genetic variability and lifetime exposures, and answers your questions with honesty and integrity. Here in our offices, that’s what you’ll find. Tricia J. O'Brien, MD's mission is to provide personalized, high-quality care with a servant heart. Dr O'Brien's distinctive education and training lends her the ability to manage your acute illness or help you to unravel complex health issues through a Functional Medicine approach.
Dr O'Brien was born and raised in rural Massachusetts. She relocated to Texas after high school and worked full-time to put herself through a Bachelor's of Science degree, graduating magna cum laude, from the prestigious University of Dallas. After completing all requirements, she graduated from Baylor College of Medicine in 2006. She attended both General Surgery and Family Medicine residencies at University of Texas Southwestern in Dallas, Texas training at Parkland Hospital, Children's Medical Center of Dallas, and University Hospitals. During her education and residency, both of Dr O'Brien's parents were diagnosed with rare forms of cancer. Her experience as a caretaker offered insight into the healthcare system from a point of view that she may not have otherwise gained. Traveling with each parent to the best facilities available, she saw time and again that there was a need in medicine to address the whole person--not just the disease. There was a vital, human element that was missing. In treating her patients and advocating for her parents, she found the value in incorporating holistic treatments into the traditional medical model. In order to fill the voids she found in the conventional healthcare system she changed the focus of her career and began training in Functional Medicine with the Institute for Functional Medicine to change the practice of medicine and how medicine is practiced.
Dr O'Brien is a Certified Practitioner with and an active member of the Institute for Functional Medicine having completed advanced training and rigorous testing. Dr O'Brien is married to her husband, Brian, and lives in Frisco with her children. Her interests include rose gardening, traveling, non-toxic living, and public health advocacy.
