Gaithersburg Animal Hospital History

The veterinary practice which later became Gaithersburg Animal Hospital started in 1957 when Dr. Robert Lehman purchased the hospital from Dr. Willbanks. The practice at that time was located in a home at 10 Park Avenue Gaithersburg, MD. The practice was purchased, along with the house, for $35,000. Dr. Lehman remodeled the basement into a veterinary practice with a waiting room, small office, exam room, treatment area and surgery room. He had a drug room for all of the large animal medications and a kennel. The practice at this time was both large and small animals. Dr. Lehman also converted a plumbers truck into a veterinary truck as there were none on the market at that time.

In 1963, Ann Limparis (now Lehman) started working part time for Dr. Bob Lehman. At this time, the character of the Gaithersburg area was changing as farms were sold and cows sent to farms in other areas. Dr. Lehman, although he loved the dairy work, decided he wanted to stay in Gaithersburg and became a small animal practitioner.

In April 1964, the practice moved to 118 N. Frederick Ave. where Tires Plus now stands. In October 1964, the hospital now known as Gaithersburg Veterinary Hospital temporarily closed for medical reasons. In August of 1965, Dr. John Keeler purchased the practice from Dr. Bob Lehman and changed the name to Gaithersburg Animal Hospital. It was the only veterinary practice between Rockville and Frederick at this time. At this time, Ann Limparis (now Lehman) came back to the practice full time.

In 1966, Ms. Limparis enrolled in a program at the Merganthaler Vocational High School to learn how to assist veterinarians. This was not a state sanctioned program but Ms. Limparis graduated this first veterinary assistant program in the state of Maryland in May 1967.

In 1969, Dr. Lehman repurchased the practice of Gaithersburg Animal Hospital. He hired Dr. Irvin Baas to work part time. In April 1973, Dr. Lehman passed away but his wife, Ann Lehman, retained ownership and Dr. Baas, Dr. Robert Whitney, Dr. David Johnson and Dr. Gene New kept the practice going. At this time, Ms. Lehman was the only non-veterinarian to own an animal practice in the state of Maryland.

In June 1978, Ms. Lehman passed the Animal Technicians exam given for the first time in the State of Maryland and Dr. Debbie McMichael started working part time at the hospital.

In Ocober 1979, the state decided to widen Route 355 so the practice moved to 280 N. Frederick Ave., its current location. At this time, Dr. McMichael was working full time with Dr. Linda Rawls, Dr. Baas, Dr. Whitney, Dr. Johnson, Dr. New, Dr. Mary Leeds and Dr. Christina Chambreau part time.

In October 1984, Ms. Lehman was appointed by the State Board of Veterinary Medical Examiners to serve on the Veterinary Technician Committee, she currently still serves today. Also, in 1984, Dr. Dan Berbert started at GAH since many of the doctors had left. Kaleen Bynaker, current office manager, started in late 1984. In December of 1984, the hospital expanded from 1100 sq. feet to 2100 sq. feet.

In December 1985, Dr. Dan and Dr. Mike Berbert purchased Gaithersburg Animal Hospital from Ms. Lehman. In July 1987, they hired Dr. Cheryl Ferendo and in July 1988, they hired Dr. Debbie Alls-Temples and Sandi Bynaker, current office manager. In July 1989, the practice got its first computer system. Dr. Lynne Haeussler and Dr. Debra Schwartz (now Sapcariu) were hired in August 1994. The practice expanded into its current size in 1995. Dr. Becky Leap started in June 2010 and Dr. Maresca in July 2014.

As seen above, the hospital has great retention with its doctors and many employees. Dr. Dan, Mike and Debbie and our managers, Kaleen and Sandi, have all been here close to 30 years; Dr. Lynne and Dr. Sapcariu 20 years. In addition, several of our employees, including Ann Lehman have been here for 15 years or longer.
