Meet Our Team


Barbra Karner, VMD

Dr. Karner grew up in Hopewell, but has lived and worked in the Butler area since graduating from the University of Pennsylvania, School of Veterinary Medicine in 1998.  She was in equine practice for 3 years.  Shortly before having her first son, she entered small animal practice where she remained for 7 years.  In 2008, Dr. Karner accepted the Medical Director position at the Vet Tech Institute in Pittsburgh.  She directed this program for 6-1/2 years.  Aside from general administration duties, her responsibilities included caring for a large number of dogs, cats, rabbits, farm animals and rodents.  She instructed numerous courses, including both small and large animal surgery and medicine.  Upon leaving the Vet Tech Institute, Dr. Karner joined a home euthanasia service for pets of all types.  She feels that humane, dignified treatment of dying pets is sometimes overlooked in veterinary medicine and at home care during this time is best for the pet and the family.  Dr. Karner continues to provide in home euthanasia services, but wanted to offer more for her clients.  With much encouragement from family and friends, she made the decision in 2015 to open Muddy Creek Animal Clinic, LLC.

Outside of the office, Dr. Karner has been the volunteer Coordinator for the Butler County Animal Response Team since 2009 and an active member since 2007.  She is a volunteer member and k-9 handler with Canine Aided Emergency Search and Rescue team.  She and her Rhodesian Ridgeback, Epi, earned their trailing certification in 2014 as members of the International Police Work Dog Association.  She is also a member of Meridian United Presbyterian Church.

At home, Dr. Karner lives with her husband, Tim, 3 sons and 1 daughter.  The family shares their 6 acre farm with one horse, 2 cows, 8 chickens, 2 rabbits, 4 dogs, 2 cats, one frog and numerous fish.  If she ever has free time, she likes to walk her dog and ride her bike.
