Dr. Grenier handles everything from routine checkups to full-mouth reconstruction, so you won’t be bounced between specialists for most procedures. His advanced training in the Air Force’s AEGD residency program means he’s comfortable with implants, extractions, root canals, IV sedation, cosmetic work, and complex prosthetics—all under one roof.

Training & Credentials

Dr. Grenier earned his doctorate at Tufts University School of Dental Medicine and completed an Advanced Education in General Dentistry (AEGD) residency at Keesler Air Force Base—an intensive program that trains military dentists to provide the full range of care, from surgery to prosthetics. He holds a Master’s degree and continues to pursue advanced training in implant dentistry through the AAID MaxiCourse program and data analytics through MIT.

He actually listened to what I was worried about, explained everything in plain English, and didn’t rush me. First dentist I’ve trusted in years.

What Makes Us Different

Most dental offices follow a standard playbook—and for straightforward cases, that works fine. But when things get more complex, cookie‑cutter approaches can miss important details. We personalize everything. That means looking at your full health picture, using advanced diagnostics to catch problems early, and building treatment plans that fit you—not just the textbook average.

Personalized Care
Three things we ask ourselves with every patient
01
What’s actually going on with this patient?

General guidelines are a starting point, but your biology, history, and risk factors are unique. We dig into the specifics before recommending anything.

02
Do we have enough information to make a confident plan?

We use 3D imaging, thorough exams, and detailed records to make sure we’re not guessing. Better information means better outcomes.

03
Are we willing to adjust when we learn more?

Treatment doesn’t always go exactly as planned. We monitor results, stay honest about what we’re seeing, and adapt the plan to what’s actually happening.

Whether you’re a patient looking for a dentist who will take the time to do things right, or a clinician interested in the science behind better care—you’re welcome here. This site is equal parts practice and lab notebook, and we’re glad you found it.
