Welcome to Great Lakes Bay Orthodontics
We Believe In Better
We are a rare combination—big-picture thinkers who live in the moment. We stay alert to new advances, trends, and technologies and are quick to incorporate them, but we never lose sight of the importance of being patient-centered. Creating beautiful smiles is where our story begins, but we keep finding new ways to write better endings.
We believe in better and smarter technology. We believe in better connections that lift spirits and brighten lives. We believe in returning something from ourselves to build a better community.

Our Treatments

Invisalign
The Invisalign system is made up of a series of custom, clear trays called aligners. They offer comfort and flexibility that can’t be beat.

Metal Braces
KLOwen custom braces are suitable for every phase of treatment, from children in Phase I to adults wanting cosmetic touch-ups.

Clear Braces
LightForce clear braces blend in with your teeth, so they’re less noticeable than traditional braces.

“All three of my children have been patients at Great Lakes Bay Orthodontics and have either finished or are in various stages of treatment. We are very pleased with how well run the practice is from the initial consult, scheduling of appointments, prompt and clear communication, friendly and professional technicians, all the way to the final appointment. Dr. Grillo provides high quality treatment, takes a genuine interest in his patients, and always has a friendly smile and kind word of encouragement. The entire staff is friendly, helpful and seem to really enjoy working with one another, which creates a warm and welcoming atmosphere. I have greatly appreciated the care my family has received and am very happy with the results!”
