Dr. Lisa Rudnick


Hello, I am Dr. Lisa Rudnick. I graduated from Purdue University Veterinary School in 2002. I practiced at a mixed animal veterinary clinic in Napolen, Ohio for 6 years. I began at Grove Veterinary Clinic in 2009 when my family and I decided to relocate back to my home town of Liberty. My husband Jason and I have two children, David and Samuel. I work part time in order to spend time with my family. We enjoy going fishing, traveling to truck and tractor pulls and the boys just love being outside on the farm. I look forward to meeting you and your pet at Grove Veterinary Clinic.
