     Cynthia C. Brinson, M.D.

Dr. Cynthia C. Brinson, born in Philadelphia, Pennsylvania, earned her undergraduate degree at the University of Texas at Austin and went on to obtain her medical doctorate at Texas Tech University, Health Science Center in Lubbock, Texas. She completed her Family Practice residency at Brackenridge Hospital in 1993, serving as the Chief Resident from 1992-1993. Dr. Brinson also completed a one-year fellowship in Academic and Research Development at the McLennan County Medical Education Research Foundation. Her favorite quote, "deserves got nothing to do with it", is a great example of the outside work she does at the Travis County Correctional Facility and David Powell Clinic. If you don't find her at any of those facilities, she's most likely enjoying her animals or shopping for the perfect shoes.

     Mary Bartz, M.D.

Dr. Mary Bartz completed her Bachelor of Biology, Cum Laude Ampla et Magna, at the University of Texas in Austin. From there she went on to complete her medical degree at the University of Texas Medical School in Houston in 1990. She returned to Austin to do her residency in Family Practice through Central Texas Medical Foundation in 1993. She joined Red River Family Practice upon completion of her residency in 1993.

Dr. Bartz enjoys traveling, especially cruising, which she has done numerous times. She also seems to always be busy in the kitchen baking treats, or spending time with their family in their garden.

Dr. Gary Werntz graduated LSU medical school in 1982. After completing a residency in Pathology at Scott and White in Temple he went into private practice in Beaumont, Texas. In 1989 he retired from Pathology, largely in response to the AIDS epidemic, and went into Family Medicine completing his residency at East Tennessee State University in 1992. He has been in practice ever since. From 2001-2004 he was the Medical Director of the David Powell Public Health Center, the City of Austin's HIV/AIDS clinic. He has been in private practice at Red River Family Practice since 2005. 

Dr. Werntz spends much of his free time at a small ranch near the Big Bend of Texas with his partner and dog Zoe. He is a fairly good gardener, and really terrible carpenter.

Although medicine plays a large role in Dr. Killian's life, he tries to spend the rest of his time farming or with his six children. Whether it's volleyball games, cub scout meetings, or harvesting this year's crop, Dr. Killian is rarely idle.
