Dr. Maryann Jacko, Dr. Jonathan Siefker, and the entire team at Wellington Dental welcome you to our practice!
Our goal is to show you how excellent oral health can benefit your life and how we can help you achieve it. Dentistry is a challenge for many patients, but we aim to provide you and your family with such a pleasant and stress-free experience that you will never avoid dental visits again!
Our dedicated team members bring a wealth of knowledge and experience to their work, and they strive to put you at ease in our warm and soothing environment. Good oral health is essential, but you will find we are a cheerful group of professionals who make dental care a thing you want to do, not a thing you have to do.
We look forward to meeting you in person, but until then, please take a moment to get to know our fantastic team.
Dr. Maryann Jacko & Dr. Jonathan Siefker
Dr. Maryann grew up in Parma, OH and attended Padua Franciscan Catholic High School. She is a graduate of Baldwin Wallace University in Berea, OH with degrees in chemistry and history. Dr. Maryann attended Ohio State University College of Dentistry, graduating in 2000.
Dr. Jon grew up on a farm outside a small town in northwest Ohio called Kalida, where he attended public school. He graduated from Vanderbilt University in Nashville, TN, then attended the Ohio State University College of Dentistry, also graduating in 2000.
Within three weeks of graduating dental school together, Dr. Maryann and Dr. Jon were married in Lakewood, OH. Dr. Maryann's earliest dental experiences took her into nursing homes where she provided dental care to the sick and elderly. Dr. Jon's earliest dental experiences were providing dental care via the Cleveland Veterans Administration Hospital.
Together, they came to Wellington in late 2002, assuming the practice built by Dr. Dane Adams. The doctors quickly outgrew their little facility on Dickson Street, leading them to build their current facility on Heritage Drive, where they have been caring for the patients of Wellington and surrounding areas for the past ten 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. Additionally, in 2010, Dr. Maryann and Dr. Jon took over the stewardship of yet another dental practice in Doylestown, OH, near Akron.
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.
