DVM

I was born here, in Logan County, and grew up on a grain and livestock farm. I attended college at the University of Illinois for my undergraduate degree in animal science and then again for veterinary school. I graduated from the University of Illinois Veterinary School with honors in 1988.

Upon graduation, I returned to the area and started working at Greenhaven Animal Clinic, where I had worked as an intern during the summers and school breaks. I have continued my education over the years with numerous seminars and conferences, also graduation from the Executive Veterinary Program at the University of Illinois. I strive to practice the highest quality veterinary medicine available.

I was lucky enough to meet my wife, Kay, shortly after graduation. We were married in May 1990, and we have been blessed with three wonderful boys: Michael, a recent PharmD graduate from St Louis College of Pharmacy; Logan who will graduate this fall from the University of Illinois in chemical engineering; and William, a junior at the University of Illinois.

In my “spare” time, I enjoy being outdoors hunting, fishing, or working landscaping. We also enjoy traveling and seeing different parts of the United States.

I realized early on that I wanted to pursue a career in veterinary medicine. In the fourth grade, we were asked the question, “Where will you be when you are 25?” I answered, “In veterinary school!”

I graduated from the University of Illinois in 2002, and joined the Greenhaven family in 2003. My interests include internal medicine, soft tissue surgery, and integrative medicine using conventional and nonconventional approaches to helping animals heal. I recently passed the testing for certification in veterinary acupuncture, and I enjoy using this modality to bring balance to our patients. I am also involved with Pets Without Parents and Operation S.A.F.E., rescue organizations that work to better the lives of animals in central Illinois.

I enjoy spending time with my family–my husband, Dr. George, and our three young boys. Our family also includes a menagerie of animals, our rambunctious dog Truman, three sweet kitties, four well fed horses, and a mix of ducks, and chickens. I also enjoy creating handmade jewelry, gardening, and reading whenever I have a little extra time.

Growing up on a small livestock farm, in Elmwood, Illinois, I always knew that I wanted to become a veterinarian. I decided to attend Monmouth College and graduated in 2013 with my Bachelors Degree in Biochemistry and Chemistry. From there, I attended the University of Illinois College of Veterinary Medicine and graduated in May of 2018.

Greenhaven is the perfect fit for me because I enjoy working with both large and small animals. My professional interests include small animal internal medicine and surgery, equine lameness and reproduction, and large animal herd health. I’m very excited to stay in Central Illinois and begin my career with such a wonderful practice.

In my spare time, I enjoy being outdoors, going kayaking, hiking and to sporting events. I have two dogs Riley and Scout and hope to have a horse in the near future. I am happy to be a member of the Greenhaven team and I’m looking forward to meeting and serving our clients!
