John Klimavicz, DVM
Dr. Klimavicz chose veterinary medicine as a career because he enjoys the interpretive approach to the medical sciences and adores animals.

Dr. Klimavicz regularly attends the DC Academy of Veterinary Medicine and is a member of the American Veterinary Medical Association.
As a veterinarian and business owner, Dr. Klimavicz’s mission is to provide high quality medicine while educating clients to be responsible pet owners.

Dr. Klimavicz often comes in on his day off, just to help his associates with tough medical decisions and emergency surgeries.
Dr. Klimavicz shares his home with Mr. Pig, a french bulldog who was rescued from a foreclosing pet store and Barkley, a lovable hound.
