The kindest thing you can do for a neighbourhood practice is tell other people about it. Our reviews live on Google, where you can read every one of them — the recent ones first.
Awesome first dermatology visit for my pup Mia due to frequent nibbling/scratching on her skin. Dr. Sullivan diagnosed the issue immediately and Mia is on her way to recovery. Yay!! I cannot say enough, good things about this doctor as well as the staff involved. Thanks so much for all that you do!! We look forward to visiting in the future for continued excellent care!
I've been going to Richey Clinic for several years, but, the service I receive since Dr. Sullivan has been there is great. His professionalism, knowledge and absolutely truly caring for the patients (animals) he sees is the best! He's been treating my older cat who is 18+ years old, he's gentle with her but thorough; at the end of the visit he always gives her a good back scratch and she knows he's trying to help her. She's not afraid! The Clinic is extremely FAIR with pricing. The office visits are NOT So PRICEY that you cant afford to treat your pet, it is very affordable. The office staff is also tremendous, they go out of their way to find time and space for your pet. I am totally sold on Richey Clinic and really appreciate everyone I come into contact with, they too CARE about the pet and you! Give them a try, I'm sure you will be totally pleased.
Went today and had an amazing experience. They tended to me and my dog quickly. We went in with an appt and only waited 5 minutes. Total visit was probably 30 minutes max. Doctor and vet tech were very friendly and knowledgeable. I will be coming back for sure. My pup got his annual shots and was treated for a parasite. 10/10
My elderly dog is in decline and went through a traumatic dog bite. He's recovering slow due to his age and yet Dr. Sullivan is taking thoughtful considerations to what to do to help making my dog heal without pain. The pricing is affordable so he's obviously not into making money but rather genuinely cares for animals.
We have been taking our pets to this clinic for many years. A few years ago, we had an experience with a staff member and a previous veterinarian that left us feeling like our concerns were not being taken seriously, and that was disappointing. Recently, however, we have brought three of our pets to the clinic, including two who needed surgery, and our experience has been very different. Dr. Sullivan has been wonderful. He listens to your concerns, takes the time to answer questions, and truly understands that pets are family members, not just animals. It is clear that he genuinely cares about both his patients and their owners. I am also very grateful for Janie and Kimberly. They have both been compassionate, caring, and supportive throughout our visits. It means a lot to have a veterinary team that understands how much our pets mean to us and takes our concerns seriously. We greatly appreciate Dr. Sullivan and his staff and are thankful for the care they have provided to our pets.
We've seen Dr Sullivan now a little over 15 years now here and at his other office. Staff is always fantastic and we have the absolute best Vet south of Houston. He's been there for my dogs as puppys, seniors, and even stayed around while we had to let one cross the rainbow bridge. Dr Sullivan is top tier. We appreciate all that his staff and himself do for our animals.
