Very professional and caring staff Very clean

On 11/1/2022 Stacy Teslenko had this to say:
Such a wonderful place with the friendliest staff. We recently decided to switch clinics because our last vet disregarded many of my concerns. We’ve only been in for 2 appointments so far and it’s safe to say that our 11 year old Golden Retriever has never gotten such good care. Dr. Orsini is as good as it gets- she is detail oriented, empathetic, caring, and very knowledgeable. Wish we found her years ago but feel very lucky to have even found her now and to have her treating and taking such good care of our Golden💛. We cannot thank you enough Dr. Orsini!
