About Us

Picture
Midstate Veterinary Services was formed in 1998 with the merger of two long established veterinary clinics, Animal Barn and Large Animal Clinic. We strive to provide high quality, responsible animal care emphasizing preventive medicine and excellent customer service with 24 hour care for our clients.
Midstate Veterinary Services recently opened a new modern 6,000 sq. ft. facility on Rte. 13 just south of Cortland. As a full service mixed animal practice we offer in-house care of companion animals and on farm care of large animals specializing in a variety of dairy and equine services. The staff, with over 62 years of combined service, and 10 DVMs are committed to providing personal attention to the individual concerns and needs of our patients and their owners.
