Client Testimonials & Reviews

Our staff at Merrimack Veterinary Hospital values feedback from our clients. Here is just a small sample of the hundreds of happy and healthy pets that we have cared for since 1991.

I love this place, the staff is so friendly. They're attentive and compassionate to both the animals and the client. My cats have been boarded there numerous times and I'm always satisfied with the care and I know they're in good hands. Also, I feel the staff do what they can to solve any issues.

Dr. Gonsalves was very attentive and diagnosed my cat Opus' thyroid and other issues correctly and quickly. He has regained all of the weight he had lost and is more active than he has been in many months. Scheduling has been a breeze and staff has been wonderful. I would give them 10 stars...

I have had many experiences here. Best vet I have ever been to. Their compassion when I lost my best friend was unbelievable. And now with our new rescues, I just can't say enough.
