About Us

Edmund P. “Ted” Williams, IV, MD

Personal Description & Philosophy of Treatment:

Psychiatrist, Dr. Ted Williams, founder of Genesis Behavioral Health in 2002, began his medical career in Family Medicine – not Psychiatry – which may be one reason why he and his clinic maintain a perspective of mental health treatment in the context of ‘family,’ and of you as a ‘whole person’ (one’s overall mental, physical, and spiritual health). Dr. Williams’ goal is to provide a clinic where patients find cutting edge, compassionate, and comprehensive ‘whole-person’ psychiatric treatment in a warm, professional setting.” In addition, he believes that a person’s growth in faith and relationship with God can be an important part of their healing, especially because many of life’s struggles don’t have easy answers. His approach to treatment is warm, non-judgmental, and professional, and he will talk about faith as much or as little as you like.

What Dr. Williams’ Colleagues Say About Him:

Gary Dunham PA-C

Gary possesses extensive medical knowledge gained from over 40 years of a wide variety of medical experience and brings this to bear on the life problems brought to him by his patients. He takes a whole person approach to diagnosis and treatment and considers faith a major contributor to healing and awareness of a person’s relationship with God a factor to be explored.

Gary’s guiding philosophy is that if a patient understands why a particular therapy is being recommended then the outcomes are much improved.

He is a retired US Air Force officer and his acumen and qualities enabled him to be hand-selected for a position in the White House Medical Unit in Washington, DC, serving from 1991 to 1994 providing direct medical care for the President, Vice President and their families.

A native of California, Gary has lived in San Antonio since 1976 intermittently between different military assignments and steadily since 1994 after retiring from the Air Force.

His educational background is a BS in Physician Assistant studies from the University of Nebraska at Omaha and an MA in Social Gerontology from the University of the Incarnate Word.  He has maintained national certification as a PA by board examination every 6 years since 1978.

Gary is the proud father of two daughters and the proud grandfather of two grandchildren. He and his wife have been happily married for 43 years.

Gary’s colleagues have commented that they are impressed by his extensive background in medicine and feel that this gives him a “huge advantage” in seeing the big picture in providing holistic care. They commend him for an accomplishment that he would never brag about: that he was hand selected to serve at the White House as a Physician Assistant.

Jennifer Harris PA-C

Jennifer grew up in small-town Texas but has lived in San Antonio since 2003.  She spent many years working in biological anthropology and genetics research before pursuing a career as a physician assistant.  This background instilled in her a healthy regard for current science and treatment modalities as well as a holistic approach towards medicine–that is, consideration of all aspects of a patient’s life, including religion and culture, and how this affects their physical and mental health.  Jennifer believes in listening closely to her patients and giving them the tools and information they need to achieve the best possible outcomes.


Jennifer earned a Bachelor of Arts in anthropology from Southwest Texas State University where she graduated summa cum laude, a Bachelor of Science in biology from the University of Texas at San Antonio, and a Master of Physician Assistant Studies from the University of Texas Health Science Center at San Antonio where she received the Physician Assistant Studies Outstanding Student Award and the Dr. A.
