Karen Tyndall, DVM

Born and raised on the Eastern Shore of Maryland, Dr. Karen Tyndall wanted to be a veterinarian for as long as she can remember.

In 2009, Dr. Tyndall joined the team at Oakhurst Veterinary Hospital.

Dr. Tyndall enjoys just about every aspect of veterinary medicine—internal medicine, surgery, behavioral counseling, and the relationships she forms with clients and their pets. She primarily cares for dogs and cats, and will occasionally see pocket pets like guinea pigs, rats, and mice. She has professional interest in feline medicine and is happy to provide care for even the feistiest of kitties.

Dr. Tyndall also has two furry children at home; Riley, a sweet and handsome hunk of a kitty, and Stevie Ray, a silly, adorable, and mischievous little boy kitten. Though she doesn’t have any dogs at this time, she plans to add to her pet family soon.

Kim Donovan, DVM

Dr. Kimberly Donovan, Veterinarian and Medical Director, received her degree in veterinary medicine from Ross University in 1997.

These valuable lessons and the bonds she developed with her own pets encouraged her to pursue a career in veterinary medicine. Dr. Donovan feels that helping other pet owners maintain and cherish the irreplaceable bonds they have with their pets is a vital part of her veterinary ideology. In addition, Dr. Donovan volunteers her time to teach pet CPR training to first responder students and anesthesia at SPC to veterinary technology students.
