About Dr. Mark Simkins
Just off Lone Tree Way in Antioch, there’s a dental practice handling everything from routine cleanings to more involved procedures. Dr. Mark Simkins covers fillings, crowns, and extractions, along with the usual checkups and X-rays. The office sits at 2730 Lone Tree Wy STE 2, a few blocks from the highway but without the traffic noise you’d expect. It’s one of those places where you can schedule a basic exam or sort out a chipped tooth without the back-and-forth of referrals.
Dentist visits aren’t exactly anyone’s idea of a good time, but having a spot that doesn’t overcomplicate things helps. If you’re mapping it out, the directions are straightforward—no confusing side streets or hidden entrances. Questions about availability or procedures? The front desk picks up at (925) 757-5000. This part of Antioch keeps it low-key, with strip malls and office parks that don’t pretend to be anything fancier than what they are.
