About Hannan Mark E DDS

Dental practices in smaller cities often fill a dual role—providing routine care while serving as a neighborhood anchor. Oshkosh’s dental landscape reflects this, with clinics spread across its mix of historic and modern districts. Hannan Mark E DDS fits into this pattern, offering general dentistry in a professional setting along North Koeller Street.

The address at 450 N Koeller St #4111 places the office near the intersection of commercial and residential zones, making it accessible for both downtown workers and nearby residents. This part of Oshkosh blends mid-century buildings with newer developments, a microcosm of the city’s gradual growth. Dentistry here isn’t just about fillings and cleanings; it’s part of the daily rhythm for families, retirees, and students from the university just a short drive away.

Services like exams, crowns, and preventive care form the backbone of most dental practices, and this one follows that framework. Some patients arrive for quick check-ups, while others schedule more involved procedures—all within the same unassuming suite. The phone line at (920) 231-0774 connects directly to the office for appointments or questions, keeping the process simple.

Finding the location is straightforward with directions here. The building’s number is clearly marked, and the surrounding streets are easy to navigate. It’s the kind of place you pass daily before realizing it’s been there for years.
