Our story

Generations of Smiles.

Two towns, one family-owned practice — carried forward with care.

Keene · since 1982

The original Old Betsy Road office.

Founded by Dr. Brady Rusk in 1982, entrusted to Dr. Dan Mertz in 2015, and carried forward by Dr. Argyle and Dr. Bennion since 2021. The same building, the same warm welcome — three generations of Keene families now sit in our chairs.

Joshua · decades of trust

A legacy we're proud to carry forward.

A practice Joshua has trusted since Dr. Gene Dewitt's day — a legacy we're proud to carry forward, with the same gentle pace and the same neighborly feel.

What we believe

Treated Like Family.

The way we wish every dental office worked — and the standard we hold ourselves to every day.

🤝

Honest, No-Pressure Care

We won't sell you work you don't need. If something can wait, we'll tell you. If it can't, we'll explain why.

❤️

Treated Like Family

You'll be remembered, greeted by name, and never rushed. The team that hands you a warm neck wrap is the same team that hands your kids a sticker.

🌿

Comfort for the Anxious

If the dentist isn't your favorite place, you're in the right office. Calm pace, gentle hands, sedation when you want it.

🏙️

Small-Town Feel, Big-City Results

Same-day crowns, in-house lab, 3D imaging, guided implant surgery — without the cold-clinic feel.

🙏

Faith & Community

We're a family-owned practice with deep roots in this community — and we try to treat every person who walks in with the kindness we'd want for our own family.

📍

Right Here, for the Long Haul

We live here. Our kids go to school here. We're not going anywhere — and we plan to be your dentist for decades, not visits.

In the chair

Careful Hands. Honest Eyes.

Every appointment starts the same way: we sit down, we listen, and we look closely — with magnification, modern imaging, and the time it takes to get it right. No upsell, no surprises, no rushing you through.

Spotlight · Joshua

Any Perez — hygienist

Patients ask for Any by name. Thorough, gentle, and the kind of hygienist who makes a cleaning feel less like a chore and more like a check-in with a friend.

Our front-desk and hygiene teams are the warm faces you'll see first, and the reason so many of our reviews mention people by name.

The experience

Small Comforts. Big Difference.

The little touches that show up across every Old Betsy practice — because the chair shouldn't feel like a chore.

🧣

Warm neck wraps

A simple touch that quietly takes the edge off.

🛋️

Cozy blankets

Because dental offices run cold and you shouldn't.

☕

Free snacks & drinks

Coffee, water, and a little something for the kids.

⏳

A calm, friendly pace

Never rushed. We sit down. We listen. We answer.

🗣️

Plain language, always

No dental jargon. We explain what, why, and what it costs.

🚂

The Keene train theme

A little signature touch at the Old Betsy Road office that kids (and grown-ups) love.
