DVM, Owner of Buckeystown Veterinary Hospital
Dr. Miller graduated from both Michigan State University (BS/BA, 1976) and The Ohio State University (DVM, 1980). Her interest in veterinary medicine was initially fueled by spending her childhood summers and holidays with her cousins on the family farms in Iowa.
In the fall of 1980, Dr. Miller met her future husband, Terry Sewell, over a Rottweiler puppy that was sick with parvovirus. The puppy lived, and they were married one year later. Terry had been breeding and showing champion Alaskan Malamutes for years, and this new exposure for Dr. Miller to practical canine reproduction and neonate care spurred a truly passionate interest in all things related to the care, well-being, medicine, surgery, and training of dogs. Terry’s business experience and knowledge of management and government forms were invaluable in the establishment of Buckeystown Veterinary Hospital in 1990.
On April 1, 1990, the hospital opened full time with only Dr. Miller, a technician, and two part-time kennel helpers. In the years since, the practice has grown to the multi-doctor, full-service practice it is now. Dr. Miller is also the owner and driving force behind the introduction of rehabilitation therapy at Buckeystown Veterinary Hospital. Buckeystown Veterinary Hospital’s philosophy will always remain the same: provide the best care for our patients as our first priority, but with respect and consideration for their owners, and do it all at a fair price.

She graduated from Chestnut Hill College in Philadelphia, Pennsylvania with a major in biology and minor in chemistry in 2008. She then completed a Master of Public Health degree with a specialization in Veterinary Public Health at The Ohio State University in 2011.

Dr. Cenera enjoyed Ohio so much she stayed to complete her DVM at Ohio State’s College of Veterinary Medicine, graduating in 2015. She was a founding officer of the college’s Veterinary Public Health club and a liaison between the College of Veterinary Medicine and a liaison between the College of Veterinary Medicine and the public as a Student Ambassador.
