DeWitt Animal Hospital - Our Staff


Jane Hill - Business Manager

Jane is a graduate of Rhode Island College. She majored in psychology and earned a teaching degree in elementary education. Jane has been married to Dr. Hill since 1977. While raising 3 (now adult) children, Jane began working at the hospital part time in 1992. She works from home performing numerous behind the scenes duties as business manager of the hospital as well as providing daycare for grandchildren.



Jim McGrath - Practice Manager

Jim joined the DeWitt Animal Hospital Team in 1982 as a part time kennel assistant. Never one to shy away from learning new tasks and excelling at them, he quickly became a valuable asset to the Hospital.

As our Practice Manager, he is the senior staff member as well as our Inventory Manager, Equipment troubleshooter and more. It has been said that “Jim has been here forever” and “he knows everything”. Of course, he’ll be the first one to say “no one knows everything”. However, with his years of experience performing various duties throughout the hospital, he is the one we call on frequently due to his extensive knowledge, as he can fill in many areas.

If you have a question, Jim almost always either has the answer or knows where to find it.

She has proven herself a reliable, knowledge asset to our team.

" I grew up surrounded by pets-cats, dogs, rabbits, ducks, a shaggy pony and nature-seeing and hearing wildlife in our yard. Some favorites were silhouette of bats in flight on summer nights, clicking and catching bugs above the trees, finding salamanders under leaf litter in early spring or an opossum scurrying across the yard late at night. I took my first job at a veterinary clinic while in high school. I have worked with small and large animals, exotics and wildlife."
