Illona M.

My dog was a patient at Deerfield for a year or so and was treated for his CHF here. When his condition worsened and it was time for him to go, we brought him to Deerfield to be put to sleep. It was a heartbreaking experience but the staff and Veterinarian made it as bearable as it could be...

Roberta C.

My husband took Tatum, our rescue Yorkie mix, to Dr. Hey this week after our experiences with another veterinary office. Dr. Hey was fabulous, thorough and showed genuine care and concern for Tatum. Did a full exam and talked to me about his findings. No pressure. Focused on the animal rather than charging us...

Lisa P.

We love Deerfield and Dr. Hey. The Front Desk staff is wonderful especially Lisa and Chelsea. Amanda and Nancy the (dental) techs are wonderful and caring as well. We've actually seen the whole staff since we've been going here so many years...

Peter M. Hey, DVM

Veterinarian

Dr. Pete Hey grew up on a ranch in Mason, Texas working cattle and goats and living a life of typical “small town” Texas. Dr. Hey then went on to College Station where he earned his DVM from the Texas A&M College of Veterinary Medicine in 1989. He met his wife, Maria, just as he was headed out the door to graduate. They were married in 1991 just a few months before Dr. Maria graduated with her DVM. They have three beautiful children, Gabriel, Malachi, and Hannah. When not providing dedicated surgical and medical care for his patients, Dr. Hey spends most of his time off with his family. He loves renovating old houses and enjoys getting back home to the ranch when he can. If Dr. Hey isn’t at the veterinary clinic, he is either at an Aggie football game or searching for the next renovation project to either rent or flip. The Hey family has a number of pets including our infamous vet hospital “greeters”, C.C. and Kiki. Woody is home with Drs. Hey and the new additions, Kleina and Bean are off to college with Hannah.
