About Geroulis Nick a DDS
The usual tune-ups for molars, cavities, and the occasional cracked filling never go out of season in Berwyn—cavities don’t take a summer break, so neither should the check-ups. Across town, Geroulis Nick a DDS keeps a steady focus on preventive care, screenings for deeper issues, and cleanings that actually stick, no extra promises attached. Cosmetic whitening sessions run alongside routine fillings, crown preps, and simple night guards, giving the office a quieter side gig beyond the drill-and-fill routine.
Up on Oak Park Avenue inside the 3340 tower, the office sits at 3340 Oak Park Ave # 202, right where the sidewalk meets the glass doors—no back-alley entrance, no hidden hallway. You’ll find it sandwiches Berwyn’s vintage bungalows with newer storefronts, a stretch that still feels like a neighborhood corridor rather than a strip mall. The building’s exterior is beige stucco; the unit on the second floor keeps the address straight without any flashy signage.
Need to lock in an appointment or bounce a quick question? Dial 708-484-4422; the line stays open between routine workdays and doesn’t vanish into voicemail after hours. Root canals and routine extractions share the roster with bite adjustments and pediatric exams—whatever lands on the calendar stays matter-of-fact, no surprises.
Print these directions ahead or let the map guide you; open the map link for real-time traffic snarls and updated floor-2 lobby notes. The stretch around 33rd and Oak Park still hums with the slow roll of older autos and the occasional freight horn on nearby tracks—classic Berwyn, where dentistry enters through a side door and exits through the same.
