Meet the Team

"The absolute best aspect of ESAH is quite simply, the PEOPLE who work there. They are supremely competent professionals who provide outstanding service and care for our cats, but more than that, they are some of the most kind-hearted, caring, and compassionate human beings I’ve ever had the pleasure of dealing with. They treat the furry members of our family, like they are members of THEIR family, and they treat my wife and I with great respect and consideration. We started bringing our pets there over 13 years ago, and we will never, never, go anywhere else. Saying “thank you” simply cannot express the fullness of gratitude we have for the wonderful doctors, technicians and staff of ESAH."  ~ P. Kopriva
