  • "Thank you to Dr. Hayman and staff for their continued help and dediction to our shelter pets. From appts on very short notice and discounts for our needy rescued dogs they stand ready to provide great care with compassion, experience and knowledge. They make these unwanted pups feel as important and loved as those currently in homes and that alone makes them wonderful if not for all the other reasons. Again... Thank You"
