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!

Licensed Veterinary Technician

Tricia graduated from the Veterinary Technology Program at Baker College of Muskegon in 2004. Immediately after graduation, she began working in the Emergency and Critical Care unit of MSU’s Veterinary Medical Center. Tricia currently lives in DeWitt and is pursuing a bachelor’s in social work at Spring Arbor University. She has a special interest in helping clients through the end-of-life care process for their beloved pets, and providing pet loss and grief support whenever she can. Tricia’s beloved best friend and faithful companion, a Pug named Vader, crossed the Rainbow Bridge in February 2020. Although her home currently lacks the pitter-patter of Pug paws, she hopes to open her home and heart to a new “foundling” soon. She loves a “grey muzzle” and has a soft heart for senior/geriatric pets.

Tricia has one adult son who resides in Los Angeles, CA, where he works as a musician and bartender. She loves the Great Lakes and all the glorious, natural wonders Michigan has to offer. Outside of work, Tricia enjoys road trips, kayaking, 5Ks, reading, and spiritual quiet time devotions.



Nicole has been with us at Eastside since May of 2019. She has her Bachelors of Science with a concentration in Pre-Veterinary Medicine from MSU. She holds a passion for Feline health, and greatly appreciates her time here because of our emphasis placed on dentistry and small exotic health- how it has revealed an interest of her own in those areas. She is very excited to apply for the DVM program at MSU with dreams of being a small animal veterinarian one day. Nicole moved to MI from Kentucky five years ago, but was born and raised in Chicago. Kodi- her fiance- lives with Nicole and their three crazy kitties; Indy, Matilda, and Oscar. For fun, she loves to read, paddleboard, clean, play Animal Crossing, or practice clarinet.
