Specializes In: Sports Medicine

Dr. Terrell Buchanan, better known as “T-Bone”, grew up as the youngest son of a farmer in Navasota, Texas. He graduated from Texas A&M with his DVM in 1966 and started his veterinary career working out of a travel trailer in the hardware store parking lot. The practice grew and expanded in many directions from that point.

In 1987, T-Bone founded Brazos Valley Equine Hospital as an equine-only medical and surgical hospital in Navasota, Texas. In recognition of the care and expertise provided over the years, BVEH has evolved into a regional hospital for Texas and several other states. BVEH has grown tremendously since T-Bone started the business with the addition of three different hospitals and twelve different veterinarians in Salado, and Cypress Texas.

T-Bone’s main interest is Equine Sports Medicine. T-Bone is a renowned practitioner and has spoken at numerous international Equine Sports Medicine conferences. He has been a mentor to hundreds of students and veterinarians. Many of the premier equine practitioners in Texas have learned from him.

T-Bone is married to his lovely wife, Cathy. They have five children all together. Two of their sons, Charlie and Ben, followed in T-Bone’s footsteps and became equine veterinarians, who also married veterinarians. T-Bone and Cathy are known as “Poppa” and “Sugar” to their grandchildren. When T-Bone is not working, he enjoys spending time with his family, hunting, fishing, and working on his property.
