About Dr. Steven L. Ash
The average dental practice isn’t hard to find along Borst Avenue. Dr. Steven L. Ash sits two-dozen doors down from the library, its sign the only one in metallic blue on that stretch of low warehouses and tidy bungalows. The building shares a lot with a muffler shop, their parking areas separated by a single lamp post that casts long shadows after four o’clock.
Walk through the glass door and you’re facing a simple hallway that ends at the reception desk; the address on the door reads 2409 Borst Ave, Centralia, WA 98531. Inside, x-rays appear on one wall, while digital forms wait on a side table next to the check-in kiosk. A quiet beep occasionally sounds from the sterilization room around the corner.
Patients mention crowns and bridges most often, but implants, fillings, cleanings, night guards, and whitening show up on treatment schedules too. Some arrive for the quick emergencies—chipped molars or sudden pain—while others schedule six-month check-ins like clockwork. The phone line lets you reserve or ask questions and can be reached at (360) 736-8380.
Parking is easiest on the east side of the lot; yellow lines keep cars from crowding the handicap spots up front. Need the path? Tap directions for turn-by-turn guidance.
