After years of driving 225 miles to my favorite dentist I decided I needed to have a dentist closer to home. I knew my first experience at Mercer Sydell would be a cleaning and exam and I knew I was facing a difficult tooth extraction. I could not be happier with the friendly, informative, gentle, professional care given by the office staff and Darian, Madison, and Doctor Mark and Doctor Sean.

I have been a patient at Mercer Sydell Dental since moving to Milton in 2017. I have always received the best care, from my routine cleanings to today's appointment with Dr. Adam for a crown prep.

He is so kind and understands that I have fear of pain--as always he assured me of what would happen, and it went exactly as he described. I highly recommend this practice for their excellent dental care, great customer service and the welcoming front office staff. Thank you!

It was most refreshing (knowing there are areas of concern) that the hygienist was professional and recognized that she didn't have to restate the obvious. I greatly appreciated her services today.

There’s something remarkable about a place that merges precision with peace—where cutting-edge care feels more like a visit to a spa than a medical appointment. That’s Mercer Sydell. Sean and Adam are not just exceptional dentists—they’re emotionally attuned professionals who lead a team that’s both highly trained and deeply empathetic. Every visit is met with warmth, grace, and an unmistakable sense that you’re in capable hands. This is a practice that’s exceptionally well run, not just in logistics, but in heart. Over the years, they’ve gone above and beyond for our family, especially in emergencies—always finding a way to make room, provide comfort, and ensure we’re cared for.

Just today, I had one of the gentlest cleanings of my life with Darian. I arrived worried—sharp ache in a molar, bracing myself for bad news. But she calmly took X-rays, gently walked me through the likely cause (a lingering sinus infection), and Dr. Mark confirmed it. I left not only with clean teeth and healthy gums—but with peace of mind. My wife often remarks how nice and prompt everyone is, and how Dr.

Sean is always available by text and quick to respond. That kind of accessibility and care is rare—and it speaks volumes. This is more than a dental office. It’s a gem of a local business—run with excellence, intention, and heart. ❤️🙏
