Dr. Jeff’s favorite activities outside of work include attending his grandchildren’s activities and going to cow shows (the latter being his most expensive hobby, according to his wife Brenda). At the clinic, Dr. Jeff says he’s been blessed to enjoy his job so much that he doesn’t even consider it “work.”

Outside of work, Dr. Medarac enjoys horseback riding and hanging out with her daughter Hannah, going on walks with her dog Amos, and watching the game with her daughter and friends. At work, Dr. Medarac loves to see appointments and perform surgery, and she especially enjoys lancing abscesses. She’s motivated by her love of her job and her love of animals.

Katie Edwards

Katie Edwards (known in a former life as Katie Majors) is Apple Grove’s office manager/chief veterinarian handler and one of our veterinary technicians. Born and raised in Laurel, she also attended Slippery Rock University and graduated from the Vet Tech Institute in Pittsburgh, PA. Prior to joining the family at Apple Grove, she worked at Brown’s Country Kitchen and also milked cows. Outside of work, she enjoys spending time kayaking with her friends and chasing around her son Clayton. At work, she loves to reorganize and declutter the clinic, as well as making sure the staff is well-fed. One of her favorite parts of working at the clinic is seeing pets grow from their first visit as a baby, as well as helping to heal pets as they’re diagnosed and treated for their illnesses.

Outside of work, Billie enjoys spending time with family and friends and working on all of her never-ending projects. At work, she enjoys cuddling and playing with the surgical patients, and she has a special love of cleaning ears (and eating snacks, although not necessarily at the same time). Billie is motivated by her love of animals and their owners, respect for her boss (the one and only Dr. Jeff McKissick), spending time with her fellow AG employees, and also a paycheck.
