I decided to try Mercerville Animal Hospital, as I found the Animal Hospital near my home (and the Princeton Junction train station) to be too expensive. I was very pleased with Mercerville. It's a small office (with low overhead) and more importantly, the vets are VERY COMPETENT. Doctor Stewart immediately diagnosed a serious condition with my dog on our first visit, without the need for a battery of tests. (This issue had been misdiagnosed by a vet I had visited while vacationing in Miami three weeks prior.) I also appreciated his direct yet compassionate style. I wish I had discovered Mercerville earlier. I find that too many larger clinics are going the way of human hospitals, with a business focus on maximizing revenue. At Mercerville, it is clear that the Vets there are in charge, they can stay true to the ideals which drove them to become Vets, and they truly care about your pet.

Dr. William J. Carter (Sr.) is the best vet in the area for diagnosing. Even without lab work, he is always right when it comes to diagnosing and treating my dogs and cats. The only other vet that has seen my cat was Dr. Stewart. He was excellent with my very shy and nervous cat and made her feel safe. The staff is great, especially Janine. Michele runs an efficient office. I guess it is in the genes! I love Dr. Carter and hope he never retires.

Very nice, knowledgeable staff...and super cheap! I recently moved from PA to NJ, so since all of my other living expenses had gone up, I expected the vet bill to do so, as well. Wrong - my friend recommended Dr. Carter (Sr.) and he was very good with handling my 3 yr old Papillon, who's very friendly but HATES going to the vet. An office visit is $30, and since my dog was due for some shots, heartworm test, etc, the total bill wound up being $107. The same procedures at my old vet (provided they haven't raised prices in the last year) would have been $145. They confirm orders placed through 1800Petmeds (something else my old vet wouldn't do...talk about greedy money makers) so I can now save on that, too. Only reason I gave it 4 stars is because the building is kind of old :) but hey, I'd rather them use their resources to provide their patients with a knowledgeable, friendly staff - which they do!

I have been going to Mercerville Animal Hospital for over 30 years. Dr. Carter Jr, Sr, and Dr. Stewart are always more than willing to answer all my questions (no matter how annoying I can be). Dr. Carter Jr was there for my family the last 6 months of my dogs life. He was so supportive and kind. I must call there 3 times per week about my one cat, and Jeanine is always willing to listen and give her advice. What a sweety! This place is truly a bargain, but dont let them know or they might raise their prices
