Our Clients Are Our Fans

Our senior dog had stopped eating, and was very lethargic. Even though we are not a regular patient, the staff was able to squeeze us in immediately,despite being booked full. Everyone was beyond kind and professional, discussing diagnosis,possible treatment, and possible outcomes, while not pushing us to hurry on a decision. We came home with solutions to try, following some in office medication. I especially appreciated the discussion of the cost before any action was taken. We are hoping for improvement over the weekend. I hope that we did not negatively impact the schedule too much.

We had an excellent experience with this animal hospital. The staff are very friendly, helpful and considerate. They took time to answer all questions and sent us home with detailed instructions. They also kept me up to date via text which was much appreciated. Highly recommend based on our positive experience. Read Less
