Dr. Marshall V. Johnson, DDS

Specialized periodontal care and dental implant services are the focus of this Plano practice. It’s one of those quiet, no-frills offices where the work speaks for itself—no flashy marketing, just the kind of place you’d expect to find in a third-floor suite along Coit Road. The address, 5800 Coit Rd Ste 300 Plano, TX 75023, puts it in a stretch of professional buildings where dentistry meets efficiency; no scenic views, just results.

As a periodontist, the practice handles the less glamorous but critical side of dental health—gum disease treatment, bone grafting, and the precise placement of implants. There’s no menu of cosmetic extras here; the focus stays on restoring function and stability. A quick check of the feedback shows a perfect 5.0 rating from 7 reviews, which, while not a massive sample, suggests consistency from those who’ve been through the door.

Logistics are straightforward: questions about procedures or scheduling can go directly to (972) 964-8833. No online booking portals or chatbots—just a phone line, the way some patients still prefer it. The practice doesn’t advertise weekend hours or extended evenings, so it’s best to call during standard business times if you’re mapping out a visit.

The area around Coit and Park hasn’t changed much over the years—strip malls, office parks, and the occasional taqueria in the same plaza. It’s the kind of Plano that doesn’t make postcards but gets things done. For exact directions, the map pin drops you at the right entrance; look for Suite 300 above the ground-level tenants.
