What our clients are saying about Brazos Oaks Animal Hospital!

Suzanne Ansley


I have been taking my fur babies (dogs and cats) to the Brazos Animal Hospital since the day they opened.  Dr Sanders and the team are fantastic.  Very caring and kind whether it’s just a visit for a general checkup, or an emotional visit to help one of my babies to the Rainbow Bridge, they treat them like they are one of their own.

I have known and seen Dr. Brent and Dr. Mary for years with my various pets.  They are excellent vets. The compassion they have shown me personally over the years is something I always appreciate.  Their staff is top-notch.  They really care about you and your et(s) and it shows.  They both use a lot of common sense when it comes to diagnosing your pets. I really don’t know what I would do with them.

When Simonton Vet was forced to close its doors we were devastated to lose such warm, caring and knowledgeable Doctors and staff!  Dr. Mary Sanders was one of those Doctors.  From having to put down a beloved pet to quickly diagnosing a pet in crisis they were extraordinary!  Now, Dr Mary and her husband, Dr Brent Sanders have opened an office in a great location and once again I have access to that quality of care!
