Definitely not recommend, very awkward experience with waiting an hour to see a vet that saw my animal for 3 minutes or less. I felt as if multiple medications were immediately pushed just to make money. Oh yeah and while i was in the waiting room, the two receptionist women were talking badly about other customers that were just there while I was in the room waiting. It was the most uncomfortable situation ever, and I contemplated leaving while I was waiting.

Very nice staff. They did a great Nail Trim. Because we made an appointment, the Dr. saw Raider quickly. We have been going here for over 5 years. Our daughter recommended this Vet and office.

Everyone is so nice, friendly and helpful. And, it is reasonable which is so nice. My dog has to have surgery to remove a growth on his right thigh. It will be under anesthesia. The cost will be around $400.00 which is very reasonable and another $175.00 to have his teeth cleaned, again super reasonable. The vets and vet techs are so nice with all the dog. They do walk-ins during the day and so it can be very busy but with an appointment you get in right away. And I think it is nice they do walk ins for people who need their animal to be seen last minute. First office visits is no charge. Nail trims are $14.00 and can be done as a walk in. Just overall very happy. We feel welcome here, our dog feels safe and well cared for, and it is convenient. Love Trinity

I found out why so many people with dogs flock to this place. I brought one of my puppies for emergency and I was very impressed with the care and treatment we got from Dr. korrolos. Since then, I bring all my three dogs there and did not go back to our former Doctor. Dr. Korrolos is the reason why this place is so busy. Not only is he nice , He is also, a well experienced, knowledgeable and great doctor.

I took my little Chihuahua Peanut in with a broken paw, Dr. K took such good care of him for the 5 months he had to have his cast. The staff were so good with Peanut, Karin and Catherine are amazing. I highly recommend taking your animals to Trinity.

I discovered that Trinity helps an organization that rescues pups because I was fostering for the and would take the fosters for needed treatment. I switched to Trinity after about 5 years when my pup needed to be fixed so I could foster. After checking my then Vet's cost versus Trinity I decided Trinity is the one for me. Their staff are helpful and concerned about pet.
I recommend them to anyone who needs quality care for their pet.

Customer Testimonials

Absolutely the best vet my animals have ever had. He is such a kind and honest person. I have a rescue shihitzu with a lot of behavior issues. I was so surprised to see my dog let the Dr examine him and didn't try and bite him or even growl. This is so outta character for my dog. I know he felt the drs good energy. The staff is amazing as well. I highly recommend trinity pet hospital.


I have been using Trinity for about 4 years now. Their prices are reasonable and the staff is incredibly estute.
Dr K is a diagnostic genius and has saved me months of exploratory lab work and literally thousands of dollars by narrowing the possible culprits and tests in order of likelihood.
He is a kind, compassionate and very wise man. Don't go to Trinity if you haven't already... I want to keep them a secret!


Been taking my dog there for 5 years. Very busy office , be prepared to wait. But prices are great and Dr. K is amazing & very thorough and patient
