Client Testimonials

I really appreciated the way the doctors at the clinic cared for Diamond. Over fifteen years of love with my wonderful dog and the quality of regular care she received at the clinic made it possible. I was especially touched by the sympathy card I receive after sadly having to put her to sleep, it shows they really care.

The staff at Zimmerman Veterinary Clinic has taken care of my dogs since 1979. I am especially pleased with the care of my last companion/friend, Ruby Mae. She received the best care I could have expected. The staff gave her loving care and attention during her whole lifetime. I canít thank them enough for being there for support. I will continue to use them with my new friend, Baily Sue.
