Meet our Staff

Dr. Kathy Kallay (Owner/Veterinarian)

Dr. Kathy Kallay believes that animals should be cared for in a conscientious, responsible manner. Education is an important part of her relationship with clients, because better-informed clients have longer, healthier relationships with their pets. As the owner of Four Paws, she is committed to provide exceptional customer service and the highest quality medical care.

Dr. Kallay’s medical interests include Internal Medicine, Behavior, Dentistry, and Surgery. She has received advanced training in all of these disciplines. She is a member of the American Veterinary Medical Association (AVMA), the American Society for the Prevention of Cruelty to Animals (ASPCA), and Phi Zeta, a veterinary honor society.

Outside of work, she enjoys reading, walking her dogs, and kayaking on our local waterways. She is also an avid photographer and has won multiple awards in amateur competitions.

A native of Southern California, she moved to Fredericksburg in 2001 following graduation from the College of Veterinary Medicine at Kansas State University. She has been practicing veterinary medicine locally since 2001. Four Paws opened in 2006 as a result of her desire to provide a high quality, compassionate, and professional hospital closer to her home in Spotsylvania County.

Dr. Kallay adopted all of her pets from animal shelters or rescue groups: Merlin, a 15-year old Hound/Border Collie mix; Hobbes, a 3-year old all round mutt, Willow, a 3-year old  Border Collie mix, and Domino, an adult black and white domestic shorthaired cat.

Community service is a way of life for Dr. Kallay. She has been a puppy-raiser for Canine Companions for Independence (CCI), and has performed therapy visits in the community with her previous dog Scarlett.  She was a Big Sister with Rappahannock Big Brothers Big Sisters, and volunteered with Team River Runner helping wounded veterans.

Dr. Kallay has been hosted on Business Link.  Hear host Frank Hammon ask Dr. Kallay about keeping your pets healthy.  Part 1 (26MB MP3). Part 2 (27MB MP3).
