He subsequently completed a one-year internship at Littleton Large Animal Clinic in Colorado, followed by a three-year residency in Equine Surgery at the University of California-Davis. Dr. Symm has been in private practice since 2007, predominately in surgical/referral equine settings, namely Retama Equine in San Antonio and Texas Equine Hospital in Bryan.

He was fortunate to grow up here, in the heart of the Texas Hill Country, and spent many hours fishing the Guadalupe River near his parents’ home in Hunt. He remains an avid fisherman and is rapidly convincing his sons to follow in his footsteps (fishing at least). Dr. Symm is an ardent athlete, having completed two half-ironman triathlons, as well as six marathons and countless other competitions. Dr. Symm is also a private pilot (VFR rated), a hobby artist, and an aspiring permaculturist.
