Maryann Jacko, DDS and Jonathan R. Siefker, DDS

Superior Care from Our Family to Yours

Welcome to Wellington Dental! We are a family-friendly dental practice that serves friends and neighbors in Wellington, Oberlin, LaGrange, Penfield, Pittsfield, and surrounding areas with state-of-the-art dentistry in a warm and welcoming environment.

As a husband-and-wife team, Dr. Maryann Jacko and Dr. Jonathan Siefker bring the same positive energy and dedication to their practice that they bring to their home life. They opened their Wellington practice in 2003 and participate in countless hours of continuing education to ensure that you always receive the most updated treatments available.

We know that lots of people don’t like visiting the dentist. But your family deserves the very best that dentistry has to offer, so we want to make your visits pleasant and even enjoyable! When you visit us, you will be treated with warmth and friendliness by compassionate professionals who put your needs and comfort first. 

Our goal is to show you that modern dentistry and technology make treatments fast, comfortable, and productive, whether you're needing Dental Implants, Root Canal Therapy, Dental Extractions, Dental Crowns, or Pediatric Dentistry for your children our office is here for you. Soothing amenities like warm blankets, neck pillows, and TVs in our treatment rooms help us create a positive experience so returning to our office for necessary treatments is a pleasure, not a chore. You shouldn’t have to spend a moment longer than necessary in the dental chair, so we help you get in, get out, and get on with your life.

We Help You Focus on Your Oral Health

You deserve to enjoy the benefits of good oral health, and you can do that by being proactive with your oral health care. But that doesn’t mean your life should revolve around your dentistry!

Our hours are designed to fit your schedule. At Wellington Dental, we stay open on Mondays and Tuesdays until 6 PM and open at 7 AM on Thursdays and Fridays so you can arrange to see us before or after school or work. We can usually treat emergencies the same day, and if it is after hours, just call our main number and follow instructions to get in touch with our doctors.

It can be a challenge to understand dental insurance, so we are happy to assist you with any questions you may have. We are a provider for Delta Dental Premier and Connection Dental but will be happy to file all insurance claims on your behalf.

Uninsured? No problem! We accept major credit cards as well as CareCredit, an interest-free financing option that lets you choose a manageable monthly payment amount. With CareCredit, you get the care you need when you need it, and as long as you pay the balance in a timely manner, you won’t be charged any interest.

Your Healthy, Beautiful Smile Starts Here
