Dr. David Buelna and staff are amazing. I was so scared for my dog seeing blood in his vomit. Asked for an appointment immediately. They didn’t have an opening but squeezed me in based on my urgency. I am so grateful. The vet assistant was so amazing in getting all our details sorted quickly. Dr. David Buelna at Circle B is a remarkable Veterinarian. We took our dog in for a check up with a serious scare. He made our dog feel completely comfortable by getting down and sitting on the floor and checking him without stressing him out. He was super knowledgeable and put our minds at ease after his assessment. His demeanor and pleasant personality along with his medical competence was so reassuring. Greatly appreciated and very impressed. We left within 30 minutes at 1/10th of the bill quoted by the ER the night before. My lesson from this is to get an appointment with Circle B before they close for the day if I detect my dog is unwell. Love them. Recommend them very highly.

Thank you, Dr. Molly for everything you’ve done for Emma and my family Circle B Veterinarian Hospital in Katy Texas is a excellent I find the staff very courteous and polite and always do their best to make sure your visit is a pleasant experience .Dr. David gives your pet all his attention and never makes you feel rushed. He takes the time to listen to your questions and always provides great feedback and distraction fir your pet’s well being and care. One of the best Veterinary care facilities I have experienced. Recently in early April 2021, had my Senior Dog a Collie in for check-up and for blood work. I had the pleasure of working with Dr.Chow, She was excellent, She spent nearly 15 minutes going over all my concerns and recommended some natural supplements for improved digestive functions as well as a medication for my pet's arthritis.So far the results have been very encouraging and my Senior girl is more active and doing considerably better. Dr. Chow thank you again for all your kindness towards my pet and myself. I encourage anyone looking for a special place to take their pet I recommend Circle B Veterinary Hospital.

They continue to provide excellent care and follow up, You always feel welcomed and all your question are always treated with respect and Kindness. Highly Recommend 10/10!

Great clinic. On multiple occasions they have worked my pets into their busy schedule, and not all clinics are willing to do that. Great for your regular check ups and their pharmacy direct ships your flea treatment which makes it easier to stay on schedule.

We were recommended by our usual vet to see Dr Buelna at Circle B for help in getting an international health certificate for our dog in preparation for our move to France. I called around to several other vet clinics in town as well and Circle B was very reasonably priced (not the most expensive but not suspiciously cheap!). The process was very smooth and they were able to get our records from our usual vet clinic to make sure they had all the info needed. At the appointment, both Dr Buelna and the vet technician were very friendly and professional. Excellent communication from both of them! There was a slight snag with our rabies certificate missing some key info, but Dr. Buelna was incredibly patient and understanding and helped me work with the vet who had administered the vaccine to get it right to ensure no kick backs from the USDA. Thankfully the USDA played their part and got the Health Certificate endorsed and mailed on time for us to make our flight to France! Highly recommend the team at Circle B for international health certificates!

All of the staff at Circle B Veterinary Hospital are wonderful! Dr. David and Dr.Obergfell are awesome with my cats, Zoë and Ollie! One can tell of their love for animals just by their gentle and kind "bedside manner". Zoë and Ollie love Dr. David Buelna and Dr. Molly Obergfell.

I really just want to thank everyone at Circle B from the front office staff and, especially Dr. David. Every time I called with concerns about my elderly dog Sonic they were always so kind. Dr. David performed a difficult surgery to remove a large tumor on my 14 year old dogs tongue. Truly, saved his life. Every time Dr. David called with updates he had so much compassion and you could tell he really loves the animals he cares for. Sonic has made a full recovery and is back to his old self. From the bottom of my heart, thank you!! I will forever trust Circle B to take care of all 3 of my dogs.

CircleB Veterinary is by far the best in Katy. They are very passionate in what they provide to pets and their families. I would highly recommend their service! Very satisfied customers!

I brought my 18-year-old cat to Circle B just two days ago for severe constipation. He was in so much pain, and I was absolutely terrified that I was going to lose him. From the moment we arrived, Dr. Strother, Kayla, and the entire team treated my cat and me with so much kindness and compassion. They took the time to explain every step of his treatment, including the risks, so I always knew exactly what was happening. I never once felt rushed or left in the dark. After his procedure, my baby still wasn't acting like himself, and they recommended keeping him on fluids to help him regain his strength. Throughout his stay, Dr. Strother called me several times with updates, which meant more to me than I can put into words. Knowing how he was doing and hearing that he was being so closely monitored gave me so much peace of mind during that horribly stressful time. What truly amazed me was the care didn't stop when we left. The day after we brought him home, one of the veterinary technicians called just to check on him and see how he was doing. That level of genuine care is something I've never experienced before. After just two days at Circle B, my boy is back to his happy, healthy self. I can honestly say I have never felt more reassured that my baby was in such capable, compassionate hands. Every single person we interacted with treated him as if he were their own, and that made all the difference to me and my family. Thank you to Dr. Strother, Kayla, and the entire Circle B team for giving my sweet old boy such exceptional care. I will forever be grateful to them. I cannot recommend Circle B enough!

Dr Molly is always amazing and super kind!!

Dr David took are of our sweet Lab, Bella during her final years, especially on the last day of her life. She was so cared for and loved by Dr David and the staff at Circle B. We are back for Dr David to care for our new lab puppy, Sophie. We are confident she is getting the best care possible.
