Together, they came to Doylestown, caretaking the practice built by Dr. Olin Bleichrodt. They quickly remodeled and upgraded their Civil-War-era building to provide 21st century dental care for the people of Doylestown, Chippewa Township and the surrounding areas for the past eight-plus years

During this time of building a growing, thriving practice, Dr. Maryann and Dr. Jon started their family and have three incredible children, Andrew (age 12), Jack (age 9), and Elizabeth (age 8). The family has been living in Medina for the past 13 years. They love the honest, hardworking people they have met over the years, and they enjoy learning new ways to enhance the dental health of their patients. Dr. Maryann and Dr. Jon are also caretakers of a dental practice in the small town of Wellington, in southern Lorain County.

Family and friends are very important to Dr. Jon and Dr. Maryann. Most of their free time is consumed with their children's activities. They also love to travel, usually with their family.
