Dr. Lisa Rudnick

Veterinarian

Hello, I am Dr. Lisa Rudnick. I am a 2002 graduate of Purdue University Veterinary School. I practiced at a mixed animal veterinary practice in Northwest Ohio for 6 years and then 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. Our children are now both in high school and they both enjoy 4-H and all aspects of dealing with the family farm. We have four dogs- Mater, Norman, Dale and Bella- three cats- Doug, Casper and Steve. We also raise sheep and show pigs for 4-H. I look forward to meeting you and your pet at Grove Veterinary Clinic!
