Dr. Stephanie Purnomo

Ever notice how a simple dental checkup can turn into an unexpected conversation about the neighborhood? That’s the kind of place Dr. Stephanie Purnomo has become for Chino Hills locals. Routine cleanings, fillings, and even those less-talked-about procedures like root canals or teeth whitening happen here—without the usual fuss. It’s the kind of practice that doesn’t need flashy ads; word spreads quietly among families who’ve lived in the area for years.

The office sits just off Grand Avenue, where the hum of weekday traffic gives way to the quieter rhythm of a residential stretch. At 3410 Grand Ave F, Chino Hills, CA 91709, the building blends into the landscape, easy to miss if you’re not looking for it. Yet, for those who’ve made it their go-to for everything from pediatric dentistry to crowns, it’s a familiar stop on the way to the grocery store or the kids’ soccer practice.

Dentistry in this part of town often feels like a necessary chore, but places like this one remind you it doesn’t have to be. Preventive care, emergency visits, and even cosmetic touch-ups are handled with the kind of efficiency that comes from years of practice—not that you’d know it from the outside. The focus stays on the work, not the window dressing, which is probably why so many patients keep coming back.
