Dr. O’Brien received his dental degree from the University of Texas, Houston Dental Branch, and did his undergraduate work at Texas A&M University. He has been a private practice Houston dentist at his current location since he graduated.
In addition to his practice of general dentistry, which includes all aspects of general and cosmetic dentistry, Dr. O’Brien has been treating dental trauma and sports related dental-facial injuries for over 25 years. He is currently the Team Dental Consultant for the Houston Rockets, a position he has held for the past 27 years, as well as the Team Dentist for the Houston Texans, the Houston Dynamo, Houston Baptist University, University of Houston, and the WWE in Houston.
Dr. O’Brien’s greatest joy is to share the gospel of Jesus Christ, and he feels like dentistry is his ministry. He is a founding Director and President of the Honduras Dental Project and volunteers his time visiting Honduras, Central America, annually to provide dental services to those who need them most.
