VCA Rossmoor-El Dorado Animal Hospital is situated in Old Town, Los Alamitos, on Los Alamitos Blvd. Once a farm town, Los Alamitos is now a center for shopping for the many residential communities around it. In 1966, a recent graduate of U.C. Davis, Dr. Crawford, bought the cement block building that once was the town barber shop and pool hall. He converted it into a one-doctor animal hospital. In 1968, the hospital was purchased by Dr. Arlie Toulouse. Then in 1969, Dr. Jerry Gardner was added as a second veterinarian. Dr. Gardner also did horse practice for the many stables then around the area. With business increasing, Dr. Charles Jenner was added to the staff in 1970 after leaving Lakewood Animal Hospital. In 1971, the hospital was expanded to include a new lobby, office and exam rooms. Eventually, the small animal practice grew to include up to seven doctors, including Dr. John Greenlee. In 1973 a new surgical wing was built including an addition of a private parking lot. During that time, the hospital saw not only dogs and cats, but many exotic animals such as ocelots, a pet Puma, snakes, monkeys and even a pet African Lion.
In 1976, Doctors Toulouse, Jenner and Greenlee joined in a partnership until Dr. Toulouse sold his share to his partners in 1988. The Veterinary Centers of America (VCA) became interested in the busy hospital and purchased the small animal practice in 1993. In 1999, Dr John Heit's Rossmoor Center Animal Clinic was merged with VCA Rossmoor-El Dorado Animal Hospital. In 2001, the hospital was recognized by the American Animal Hospital Association (AAHA) for 25 years of accreditation. Only about 800 general practices nationwide carry this distinction of practice excellence for 25 or more years. VCA Rossmoor now has 5 veterinarians, one of which practices acupuncture and also a pet chiropractor
