Dr. Ryan Tomasini


Ryan Tomasini, DVM grew up in South Texas, spending most of his childhood in San Antonio. Dr. Tomasini is proud to be part of the team at Olmos Park Animal Hospital.

Besides spending time with his family, Dr. Tomasini enjoys working outside at the ranch, hunting, fishing, and wood working when time allows.

Dr. C. Craig Corder


Curran Craig Corder knew from his knees-to-a-grasshopper days that he would grow up in a realm surrounded by animals. Gravitating to those world’s citizens who will always tell the truth, should we fallible humans care to listen, he broke his adult teeth volunteering, and then working, for his family veterinarian from junior high through high school. Graduating from Texas A&M University School of Veterinary Medicine in 1979, he made his way to the River City to practice the profession best respecting the well-being and betterment of companion animals through a lifetime of dedication. Slightly more than three years of private practice allowed absorption of enough business acumen to permit branching out on his own at the site housing the present practice. Three decades of dedication to the betterment of companion animals in s small practice has provided an exceedingly gratifying basis for an enriched life serving those world citizens who he still feel base the truest of Nature’s creatures. More than thirty years after first opening, when Dr. Ann Cross walked through the clinic’s threshold, a quick friendship budded, and then grew, into a trusting partnership. Dr. Corder’s life dream was able to proceed anew by the addition of her able and trustworthy devotion, after which both pattern their lives.
