We are proud to announce that we are among the 15% of AAHA accredited hospitals. AAHA is The American Animal Hospital Association which sets the standard for veterinary excellence. It is the only voluntary accreditation program for veterinary hospitals and is used as a benchmark to measure excellence in veterinary medicine. This certification ensures that our hospital is held to high standards and enhances our ability to provide the best care possible. 

To be accredited by AAHA our hospital must demonstrate an exceptional level of medical care and client service. We are evaluated by over 900 standards which are periodically reviewed and updated to ensure they remain consistent with the changes in veterinary medicine and technology along with hospital visits and evaluations. This rigorous evaluation includes patient care, record keeping, pain management, hospital cleanliness, surgical techniques, safety precautions, proper employee training, employee continuing education, and radiographic evaluation. To maintain accreditation our hospital must be evaluated every three years to ensure that we are keeping up with this ever changing and growing profession.

Hospital History

Warren Woods Veterinary Hospital was opened November 17, 1966 by Doctor William Mullan. Dr. Mullan graduated from Pennsylvannia State University in 1959 as a Veterinary Medical Doctor. During his schooling, he completed a 15 month internship at Angel Memorial Veterinary Hospital in Boston. Dr. Mullan served as president for both the Macomb Veterinary Association and the Southeastern Michigan Veterinary Medical Association, and was on the veterinary medicine licensing board for nine years. Dr. Mullan is now retired and living in Warren. 

Dr. Leroy joined the Warren Woods team as a partner in ownership with Dr. Mullan in March of 1968 until he passed away in April of 1970. Dr. Mullan did not have another partner until March of 1985 when Dr. Evans joined the team. Dr. Cappel started working at Warren Woods in June of 1991 and in July of 1997 she bought Dr. Mullan’s share of the hospital and became an owner. When Dr Evans moved to Arizona in 1998 Dr. Cappel became the sole owner of the practice. 

Warren Woods Veterinary Hospital added an addition to the original building in 1976 to better accommodate its growing client base. For a time there were five veterinarians working at the hospital. In May of 2008 Warren Woods got a new and improved reception area complete with lots of windows, two bathrooms, two new exam rooms and kennel runs. 

At Warren Woods Veterinary Hospital, some of our team members stay only for a little while, but many stay for quite some time. We believe that once you’re in the Warren Woods family, you are always family. Many previous team members still visit our hospital, including the founder, Dr. Mullan.
