Paul D. Doodes, DDS


For Dr. Paul Doodes, dentistry is an exciting challenge – an art. More precisely, he says, “For me, dentistry is an interesting blend of education, research, medicine, art, and personal relationships.” He wants to develop personal understanding of his patients’ need as well as their desires. He delivers careful, thorough treatments that with results that make his patients smile every time they look in the mirror.

Before he moved to the US to pursue his PhD in immunology and microbiology at Rush University, Dr. Paul earned a bachelor’s degree in chemistry in the UK. Since earning his dental degree, Dr. Doodes has presented his work at national conferences and published a number of articles in scientific journals. And while he enjoys the academic work, he craved the person-to-person interaction and fulfillment of clinical dentistry.

He is a member of a number of professional organizations including the Chicago Dental Society, Illinois State Dental Society, and the American Dental Association (ADA).
