About Ronald Zambaldi DMD
Not every medical practice feels simple to parse—specialties blur into one another until you need a specific service. The dentist’s office on Collinsport Dr. fills that gap; patients come for preventive care, teeth whitening, and fillings that don’t require a trip across town. Routine cleanings anchor the menu, but implants and crowns surface often enough that the practice keeps those tools close at hand.
Start here: 3 Collinsport Dr, Collinsville, IL 62234. The building sits west of downtown, tucked between two tree-lined blocks you’ll recognize after a couple of drives past the old brick mill. No elaborate signage is needed—just pull into the lot and look for the single-story façade with dental-blue awnings.
Feel free to call before you leave the house—the team handles appointments and quick questions alike at (618) 344-6459. Emergencies sometimes surface minutes before closing, and the staff moves between routine exams and after-hours urgencies without missing a beat.
A quick glance at the map—directions here—will line things up before traffic piles up on Collinsville’s side streets. You’ll see why the office quietly stays on neighborhood speed-dials.
