Meet the Doctors
Roselle IL Dentist

Matthew J. Phan, DDS
I am proud to be part of a team who is committed to providing the utmost oral health care for its patients and the community. In a friendly and caring environment, we strive to ensure all patients have the highest quality of oral care by building relationships on trust, providing comprehensive exams, and offering educational materials that promote good dental health.
I received my Bachelors of Science in Biology from the University of Wisconsin: Madison. After graduation, I worked at the Mayo Clinic furthering vaccine research in MMR, influenza and smallpox. During this time my true passion for dentistry was sparked when I worked in a dental lab fabricating crowns and bridges. I furthered my education at the University of Minnesota’s School of Dentistry where I received my Doctorate of Dental Surgery. After working for a few years at a Minnesota dental clinic, my family and I relocated to Chicago to be closer to family.
In my free time, I enjoy exploring Chicago and its surroundings with my family, son, and 2 dogs. Most of my spare time involves working on the car, kayaking on the lake, playing soccer, and spending time with my relatives. I am an avid sports fan of UW – Madison and the Vikings
I am an engaged member of the American Dental Association, Minnesota Dental Association, the Illinois Dental Association and Chicago Dental Society
I look forward to meeting new, and current patients, to ensure everyone receives the best dental health care possible.
