Testimonial

We have had such great treatment of our dog, Maggie at River Ridge, even when we've called during off hours. From the doctors, office staff, groomers, boarding and daycare staff, everyone has been friendly and professional. Our dog loves to go there and we feel confident that she is getting the best care from everyone.
