Where Guests Become Family

Safely open To Serve You

Our Coronavirus Response

Smiles, Laughter, Friendship

Imagine contagious smiles, laughter, and friendship at the dentist. Open arms and warm smiles replace judgment and pressure. We’re different because we believe you deserve a special kind of dental experience where guests become family.

a Personal Touch

“I care for my patients like I would care for my own father and mother – with grace, a personal touch, excellent clinical care, and complete Transparency. I believe everyone deserves the very best I have to offer."

Dr. Sarah Mertz patient interaction

After a life-changing dental mission trip to Kenya, Dr. Sarah discovered her calling to serve people through dentistry. Her passion for people shines through in her practice motto, “Walk in as a stranger, be treated like family, walk out as a friend.”

Kindness And Comfort

Through the doors, you’ll discover our relaxing lounge area with refreshments, music, and a warm welcome from our team. Inviting treatment rooms continue the focus on kindness and comfort with massaging, heated chairs, and your choice of entertainment. If that doesn’t sound like a typical trip to the dentist, you’re right. Our atmosphere is exclusively designed to make you look forward to every visit.
