Mary Seager DVM

Dr. Mary Seager, D.V.M., Owner of Eastside Animal Hospital

Dr. Seager is a graduate of Michigan State University’s CVM Class of 1985. She currently lives in DeWitt with her husband Harold who has been at MSU Stores Receiving for over 40 years. They have 3 children. Jennifer, the oldest, is married and lives in Washington DC with her husband Ben and their cat Case. Jennifer is an assistant Professor at George Washington University. Their son Ian is an avid supporter of the environment and sustainable farming and will be getting his degree from MSU in agriculture studies this year. The youngest is Lauren who currently resides in Lincoln City, Oregon where she is going to school and working. She hopes to enter a branch of the medical profession.

Their 4 legged children currently consists of Delilah – a spaniel mix rescue, Maymun – a domestic shorthair feline rescue, and Aslan – a sheepdog puppy. There is currently an empty guinea pig cage that she hopes to fill again soon!

Dr. Seager began working for the Benson Animal Hospitals immediately after graduation and purchased her current location in 1991. She is a general practitioner and provides all routine health care for dogs, cats and small exotic mammals. Because of her early interest in veterinary dentistry (she completed an externship during her senior year in veterinary school with a board certified veterinary dentist), she has attended numerous hours of continuing education programs in dentistry since graduation. Two of her initial big additions to the practice after purchasing it in ’91 were a dental x-ray unit and a dental station that included a high speed hand piece with fiber-optics. In addition to dentistry, Dr Seager is also very proud to be one of the few veterinarians in the Tri-county area with over 30 years of experience giving medical treatment and performing surgery on small mammalian exotics (formerly known as “pocket-pets”). In this area, as well, she has attended several continuing education programs though out the years and is an active member of the Exotic Veterinary Medicine Forum.

Dr. Seager has always placed a high value on the importance of organized veterinary medicine and giving back to her profession and her community. She has served on the Michigan Veterinary Medical Association Board of Directors as well numerous committees of the MVMA. Locally, she has also served as president, vice president, and secretary of the Mid-State Veterinary Medical Association. Throughout the years, Dr. Seager has enjoyed volunteering at local schools for career days and general public education. In addition, Dr. Seager has also volunteered her time at Michigan State University’s CVM mentoring students in their interactive case study course and has taken part in the interviewing process for prospective new veterinary students.

In her leisure time, Dr. Seager enjoys taking dance lessons at Ann’s School of Dance and working out at a local gym. This year, Jennifer encouraged her mom to begin running as well. (And her mom has loved it!) In general, anything outdoors – from camping to boating to snow skiing – Dr. Seager is happy to participate!
