We believe in the highest-quality dental experience-both in the chair and out. When you walk in for your first appointment, you'll be greeted by a member of our team who will give you a tour of the office then walk you through some initial paperwork. If you'd rather save time before the appointment, you can download and complete the forms in your New Patient Packet beforehand.

As you wait, take advantage of our massage chair, enjoy a paraffin hand wax, or relax with a hot towel.

Throughout your appointment, our compassionate staff makes sure you are comfortable with heated massage dental chairs, headphones, support pillows and more. We take into account how your oral health affects your total health, and work with you through any anxieties you may have.

After your appointment, we help schedule your next visit with us and send you on your way with a goody bag and a healthier smile.

We are who we are because of the support of our community. That's why giving back is so important to us. Each year, we pay it back through scholarships, fundraisers, sponsoring Grossi Baseball youth teams and more.

Each Thanksgiving weekend, we hold our annual Free Dental Day event. On these days, people without dental insurance in the surrounding communities can receive free routine dental services with the donation of a nonperishable item to the Eastern Michigan Food Bank.
