Dr. Oleg Khomutets
DVM, Owner, CEO
Veterinary Emergency Care and Veterinary General Practice
Doctor Oleg was born in Magdeburg, Germany, into a military family, and from a young age, he knew that he wanted to become a veterinarian. Dr. Oleg’s passion for animal science began when he was just 12 years old. During his school years, Dr. Oleg had the unique opportunity to work with the K9 Units for the Ukrainian Police and Army, which deepened his love for veterinary medicine.
Dr. Oleg pursued education at Poltava State Agrarian University in Ukraine, where he earned a dual degree of Doctor of Veterinary Medicine and Biotechnology. After completing a companion animal emergency internship in the U.S., Dr. Oleg developed strong interests in emergency and critical care, orthopedic and soft tissue surgery, internal medicine, epidemiology, infectious diseases, and endoscopy. Dr. Oleg firmly believes that veterinary medicine plays a critical role not only in supporting the health of our pets but also in protecting human populations from dangerous zoonotic diseases. With great respect for all medical professionals, he often likes to say (with a wink) that doctors treat humans, but veterinarians treat humanity. In his free time, Dr. Oleg enjoys spending quality moments with family and staying active through exercise. Dr. Oleg lives in Northern Virginia with his beautiful wife, Hanna, who is also a veterinarian. Dr. Oleg and Dr. Maskalkova have three wonderful daughters—Vasilisa, Sophia, and Alexandra—and their home is happily shared with dogs named Candy and Buddy, and a cat named Pearl.
