What Our Clients Say
Excellent service, we have been bouncing around to different vets for 2 years trying to find one we feel comfortable with and Dr. Horst has been great, I think we are done bouncing around finally !
We have been clients/patients with Dr. Horst for over 35 years. He and his staff have always given us the best service, advice, and compassion. Our pets have benefitted in so many ways from the care they received over the years. Great staff!!
Always a great experience at the office, I don’t live in Mercersburg but in a neighboring state. I would rather come to Mercersburg Vets then any of the 3 or more Veterinary clinics in my area.
Dr. Horst has been the family Vet for years. He has cared for our horses, and various number and breeds of dogs. He has always been honest, straight forward and caring. He is not pushy nor arrogant. He is compassionate and we trust him like family.
You were able to fit us in quickly when we had a hurting dog. The diagnosis came back quickly once we were there. Great facilities and great 1st experience! We will definitely be back!
You guys always take the time to help, to answer questions, to squeeze someone in if an emergency arises. Always cheerful. Everyone there is fantastic! Thank you for being there for us!
Friendly, Clean and Very Inviting. Wish my doctor’s office was as good lol. Best Vet ever and I won’t take my dogs anywhere else but here. They listen and they care. Your pet is family and that’s how they make you feel.
