"Our beautiful, crazy, silly cat James Bond had horrible IBD. Dr Frembgen was able to treat his disease and keep him healthy and happy for 17 years! Sadly, we lost him on Leap Day February 29th, 2024. Dr Frembgen gave us wonderful and MUCH NEEDED emotional and medical support that kept us all going to the end. There are not enough words that could ever convey our thanks for "all she did for our precious "kidden" James Bond. Thank you Dr Frembgen...you are a blessing to all whose lives you touch.

- Lee & Dr Patrick M.

“I just wanted to thank you guys at the clinic for all your help with my dog Babe. Unfortunately, I moved from San Angelo and wasn't able to travel to do a final check-up with you guys. I recently got her tested and I'm happy to say she's heartworm free! I cannot express how grateful I am to your clinic for being so helpful with her treatment, you answered all my questions and were so sweet to her. I know the shot is hard to give dogs and she was often uneasy going in for check-ups, but if it wasn't for all of your effort I could have lost her. I will always be grateful for all you have done for her!”

- Dariana B.

“We love this place! Dr. Frembgen and her staff are extremely knowledgeable and friendly. About 9 months ago we bought/ rescued a beautiful 4-month-old Doberman puppy. The breeder did not crop her ears and by 4 months old, because of hardening cartilage, it’s very difficult to crop them and they’ll stand up. Dr. Frembgen gave it a shot and did an amazing job! Our Doberman’s ears stand perfectly straight! Thank you, Dr. F ! Also, she recently spayed our Doberman and they all took great care of her and there’s barely even a scar. I give them all 10 stars!"

I really appreciated this. Her staff has gone above to make me feel welcome from the minute I walk in the door until we leave. Anyone that is looking for an exceptional Veterinarian and Animal Hospital should use them. 5 stars all day!!”

"They are always so helpful and attentive even though they are steadily busy. The staff all show my fur babies so much love."

- Shantique R.

"Very impressed with the quality of care and compassion at this Veterinary hospital. And it helps that the people there have an innate knack with animals. My German Shepherd never goes to anyone, very wary, but she went straight to the tech and the doctor. Follow up care and concern was great too. Highly recommend."

- C.R.

"The vet was thorough in examining my cat, and diagnosed why he has been off balance. I previously had taken him to a different Vet and $900 later they diagnosed him with several issues and gave him medication for them, but he just got worse and developed an off balance gait. I am so glad I took him for a 2nd opinion and hopefully is on the correct treatment path now. They provided two medications for him and gave him two injections, all that at 1/4th of the cost I was charged at the first animal hospital."

- Esther S.

"Took good care of my fur baby. friendly. got me in quick."

- Myra T.

"I have been taking my dog there for 6 years and never had a problem. Awesome vets and I would refer them to anyone looking."

- Steve W.

"Just moved here and had a minor emergency with one of my dogs (blistered paw pads). Had to pick a vet to try, picked this one because of their good reviews, and I can confirm they are great. Very straightforward but also kind. Everyone there was very friendly and gentle with our dog, and she's healing up great. Affordable prices, too, which was a relief. I would highly recommend!”

- Kristin H.

"I have been going there for 18 years!! With my first dog Baxter, he lived 16 for years. They took excellent care of us and now our new puppy Cookie. Very knowledgeable and caring about both animals and humans with a lot of questions like myself!!!"

- Mary B.

"They have been great with our own animals and when I found a kitten that could not be saved they were extremely kind in helping me to help it. They have always been friendly, knowledgeable, courteous, flexible and professional, all at the same time. I have seen them go above and beyond and not just for me and mine. They may be a little pricey but when it comes to taking care of non-human family members, like so many other things, you pay for what you get and care for my fur babies is something that I believe cheapest is not always best."

- Shannon W.

“I just wanted to thank you guys at the clinic for all your help with my dog Babe. Unfortunately, I moved from San Angelo and wasn't able to travel to do a final check-up with you guys. I recently got her tested and I'm happy to say she's heartworm free! I cannot express how grateful I am to your clinic for being so helpful with her treatment, you answered all my questions and were so sweet to her. I know the shot is hard to give dogs and she was often uneasy going in for check-ups, but if it wasn't for all of your effort I could have lost her. I will always be grateful for all you have done for her!”
