What a wonderful experience!!! We were a little worried about going to a new vet because we have had the same vet for over 15 years. But this experience was unbelievable, from the receptionist to the nurse to the doctor, everyone was wonderful and friendly and efficient. Not to mention, the location is beautiful and super clean, unlike other vets we've been to. They even had a little sign in the front with the names of our dogs to welcome them in for the day! How thoughtful is that?!

I can't say enough wonderful words about the ladies who work here. From the moment we arrived for our first appointment, they make you and your pet feel comfortable and confident in the care provided all the way to the final goodbyes for our ailing pet, even making themselves available during closed hours. Highly recommend this veterinarian and her wonderful staff. Thank you for all you've done for our family.

Took my kitten to Seacoast since the other vet cancelled on me. They were so sweet, got me an appointment same day and when Stormy and I got there they were super attentive, patient, gentle and caring. They made Stormy feel very special and like the cutest cat in the world. Will definitely come back here whenever Stormy needs a check up!

Our cat took a sudden turn for the worse, and we knew that same day we had to say goodbye. My heart was already so heavy for my mom. She was losing her cat, and it had only been a few months since we lost our family dog too. It felt like too much all at once. In the middle of that grief, I got on the phone trying to find somewhere, anywhere, that could help us in time. I called five vets. Two of them were so cold and dismissive to me, and it genuinely stunned me that anyone could treat a person that way during a moment like this. The other three just didn't have room. I remember sitting there feeling so lost, wondering how I was supposed to hold everything together for my mom when I couldn't even get someone to help us. Then I found Seacoast. The receptionist who picked up changed everything. She was so gentle with me. She let me get the words out, she listened, she answered every question with so much patience, and she never once made me feel like a burden. After being brushed off twice already by the other vet clinics, her kindness hit me hard. I kept thanking her, over and over, because I didn't know how else to express what that meant to me in that moment. When my parents brought our girl in later that day, the staff met them with the same tenderness. They were gentle, caring, and present with my parents during the hardest goodbye. In her final moments, our sweet girl was calm and peaceful, surrounded by her family and by the wonderful staff at Seacoast, who treated her with as much love as we did. This clinic didn't just take care of our cat, they took care of us. They saw us as people who were hurting, not just another appointment. I will be forever grateful to Seacoast Animal Health Center for showing us so much compassion on one of the worst days of our lives. Thank you, truly, from the bottom of our hearts.

I cannot say enough good things about Dr. Adam’s and her practice. If she ever moves states we would follow her to a different state. We only trust the highest level vets to care for our dogs and Dr. Adam’s is top notch. She is resonably priced, has a high level of knowledge and empathy. Even our most reactive dogs do amazing here. This is the vet you want caring for your pets. I’ve been recommending everyone of my friends to her.

We recently had surgery done for our dog Lucy at Seacoast Animal Hospital, and I truly cannot say enough good things about our experience. Lucy had a lump removed that had grown very quickly, and from the very beginning Dr. Adams was incredibly thorough, honest, and compassionate. She took extra time to explain every possible outcome, both good and bad, if the lump came back cancerous, which we really appreciated. We never once felt rushed or left in the dark. What really stood out to us was the level of care and attention they gave Lucy before surgery even began. Dr. Adams went above and beyond by consulting with colleagues and performing additional testing free of charge just to make sure she fully understood what she was dealing with before operating. That meant so much to our family. Throughout the surgery, the team continuously texted us updates, which brought so much peace of mind during a stressful day. They also have a text line available for questions, and communication was always quick, kind, and helpful. The entire staff was warm and friendly, the hospital was extremely clean, and both drop off and pick up were smooth and organized. We are so grateful for the care Lucy received and would absolutely recommend Seacoast Animal Hospital to anyone looking for a veterinary team that truly cares about both their patients and the families behind them.
