About Us
Come for the dentistry, stay for the good company
We started with one practice and a simple belief: take care of the people around you and the rest will work out.
Families started driving past other dentists to get here. Our schedule filled faster than we could grow. So we built something that could reach more families without changing what made it work.
Good Company Dentistry is locally owned by doctors who live in the communities they serve — with the same standard of care and the same commitment to every person who walks through the door. Every location, every time.
Transformations
The best smiles come from
good company.
Every smile tells a story. Here’s what’s possible
when experience meets precision.

What Makes Us Different
Good Company
Great dentistry does not come from the fanciest equipment or the biggest office.
It comes from the people you surround yourself with. Doctors who care deeply, teams who serve wholeheartedly, and the patients who trust us with their health.
That is the foundation of Good Company Dental.
Good Doctors
Every provider we bring on is hand-picked — not just for clinical skill, but for how they treat people. Doctors who live in this community, invest in it, and genuinely care about the person sitting across from them.
Good Teams
From the first phone call to the final follow-up, every person on our team is here because they love taking care of people. The warmth you feel walking in isn't an accident — it's who we hire.
Good Patients
You're not a chart number. You're the reason we built this. We take on patients who are ready for a real relationship with their dental home — and we hold up our end every single visit.
The way dental care should feel.
We don’t just treat teeth. We take care of the person attached to them.
We listen first.
Before we look at a single X-ray, we want to hear from you. What's been bothering you. What you've been putting off. What you're hoping for. You'll never feel rushed, judged, or talked over here.
01
We educate, not pressure.
We'll show you exactly what we see and explain every option clearly. Then the decision is yours — always. No upselling, no pressure, no recommendations we wouldn't make for our own families.
02
We see the full picture.
From what needs attention today to where your smile could be in five years, we think long-term. Because the best care is proactive, not reactive — and we plan to be your dentist for life.
03
We build real relationships.
Your doctor remembers you. Your hygienist knows your history. The front desk knows your name when you walk in. That's not a small thing — that's the whole difference between a dental office and a dental home.
04
How We Can Help
Care that meets you where you are.
Whether something hurts right now, you want to stay on top of things, or you’re finally ready to do something about that smile — we’re here for all of it. No judgment on where you’re starting.
Relief
Something needs attention now
Pain, a broken tooth, something you've been putting off — we move fast when it matters. Same-day appointments available, clear answers, and a team that takes your discomfort seriously from the moment you call.
01
Maintenance
Keeping what you have
Consistent care, honest checkups, and a long-term relationship with a doctor who knows your history. The goal is a healthy smile for life — and a team who helps you actually get there.
02
Transformation
Life-changing dentistry
Veneers, implants, whitening, full smile design — for people who are ready to finally love what they see. Dr. Tanner personally handles every case and treats each transformation like it's his own. Because in a way, it is.
03
Our Specialties
The Experience
Every visit
should feel like this.
We obsess over every interaction — because the experience is the care. How you feel from the first phone call to the final follow-up matters just as much as anything that happens in the chair.
That’s how families started driving past other dentists to get here. And it’s how they keep finding their way back.
The First Call
"A real person picked up. They actually had time for me."
Walking In
"They knew my name. The doctor sat down before anyone touched anything."
The Conversation
"He showed me what he saw, explained my options, and let me decide. No pressure."
After the Visit
"They checked in on me the next day. I didn't expect that."
