Dr. Czechorski

Dr. Stefan Czechorski was born and raised in Milwaukee, Wisconsin. In the late 1980’s , almost by chance, he attended a Dale Carnegie Human relations course “Human relations and public speaking”. It was enjoyed so much that he helped instruct that 18 week course as a graduate assistant – five times. Looking back, that was when the search for his future began. He completed his academic studies at Marquette University, and Marquette University School of Dentistry. Graduating in 2001 with his Doctor of Dental Surgery Degree (DDS). After graduation he began practicing Dentistry full time in the greater Milwaukee area and within a few years returned to the Marquette campus part time to be a adjunct professor in Clinical Dentistry (in the Dental School) where he attempts to “Be the Difference”.

He is known around the office as Dr. C and focuses on addressing each patient’s dental needs while tailoring the clinical experience to each individual person. He understands that generally, each individual presents to him with very similar dental needs (for which he is highly trained), but each patient’s expectations vary greatly. And this can make the Practice of Dentistry very challenging; treating the whole patient often times involves interpreting what they are “really” saying to you. That aspect of practicing demands a empathetic approach which Dr. C understands and practices each day.

Length of treatment, costs, and the physical abilities of each patient can affect treatment outcomes considerably. Therefore, knowing their expectations is a key factor to a successful experience for both patient and practitioner; in short, making a real difference in their lives.

In his spare time, Dr. C enjoys part time teaching at Marquette and working on his own cars; in his fully equipped and heated home garage.
