Melissa Havemann, DVM

Dr. Melissa Havemann grew up in Jarrell, Texas showing in the English and Western Equine Circuit. She went to Texas A&M for her undergraduate degree in Biomedical Sciences and veterinary school. During her stay at Texas A&M, she worked as a veterinary technician in a large equine hospital, ran an equine boarding facility, and worked in an Equine Infectious Disease Lab.

After she graduated with her DVM from Texas A&M, she completed an internship at an equine referral hospital in California servicing 30 local referral veterinarians. It was during her internship that she developed her love of emergency and medical cases as well as lameness. She moved back home to Texas upon the completion of her internship and worked at one of the largest mixed animal practices in Texas at Alvarado Veterinary Clinic.

Horses are Dr. Havemann’s passion, but she can never say no to the small furry friends. In her free time, she enjoys riding her two horses, Kai and Feather, spending time with her dogs, Cooper and Barkley, and enjoying the outdoors with her husband, Denton. She is very excited to be a part of the Chisholm Trail Veterinary team and looks forward to assisting you with your animals’ needs!
