Our Vets

“We want to provide a warm and caring environment for pets and their owners while offering the best medical and surgical veterinary services.”
– Dr. Keith Robbins



Dr. Keith Robbins

Dr. Robbins is a 1996 graduate of Cornell University, College of Veterinary Medicine and has been practicing as a small-animal veterinarian ever since. After graduating from Cornell, he worked as a small animal veterinarian in rural New Jersey. After a year, Dr. Robbins moved to New York City and joined a busy, progressive Manhattan veterinary hospital. In late 2001, he moved to the Washington DC area and worked in Maryland at a small animal hospital. In April 2006, Dr. Robbins bought Catoctin Veterinary Clinic.

Dr. Robbins was attracted to Catoctin Veterinary Clinic because of the warm, caring environment and solid veterinary reputation that Dr. Clinton Pease had fostered for over 20 years. In 2006, Dr. Robbins purchased Catoctin and has been committed to continuing the open, caring, and nurturing environment of the clinic.

He currently lives in Brambleton with his wife and three children. The most recent addition to the family is a rescued dog named Elliot who Dr. Robbins endearingly refers to as “The Spoon” (not the sharpest knife….). When Dr. Robbins is not at Catoctin he enjoys playing basketball and soccer and watching his kids’ endless sporting activities. In 2018 he had the opportunity to visit Italy and Spain, which whet his appetite for travel.

Dr. Robbins, along with the other veterinarians at Catoctin Veterinary Clinic, is dedicated to providing his clients and furry patients with the best, compassionate care. He has been the owner at Catoctin for over a dozen years and fully plans on being here for at least another dozen more.

While there, she worked with a number of specialists including veterinary surgeons, neurologists, cardiologists and oncologists. Dr. Conway joined Catoctin Veterinary Clinic in 2007.

Dr. Brian Carson

 Dr. Carson comes to us from a local clinic with 4 years of experience in small animal medicine. Dr. Carson is a graduate of Cornell University just like Dr. Robbins!

Dr. Carson is originally from upstate New York and enjoys experiencing the culture of every new place he visits. He was introduced to the veterinary field as an adolescent and has continued to pursue his passion ever since. As an undergraduate, he traveled to Berlin, Germany and worked with a small animal veterinarian and various professors studying veterinary medicine and the German language. He has continued to pursue his passion for veterinary medicine in the beautiful state of Virginia. Dr. Carson is a strong believer in the human-animal bond and the joy that beloved pets introduce into our lives.
