Dr. Joshua M. Renken

Dr. Joshua Renken is a native of central Illinois. He received his undergraduate degree from Eastern Illinois University, then continued onto the University of Illinois at Chicago for dental school. He completed associate work in Chicago before founding his initial practice.

Renken Dentistry, his first dental office, opened in Springfield, IL in 2003. Through Renken Dentistry and his second practice in Springfield, Schön Dental, he became deeply involved in the local Springfield community and the professional dentistry network. As he continues to grow professionally, he has been awarded fellowships from the International Congress of Oral Implantologists and the White Cap Institute. He was voted best dentist in Springfield by The State Journal-Register’s readers in 2014 and 2015. He served as the President of the GV Black Dental Society from 2014 to 2015. Dr. Renken is a member of the communications committee of the Illinois State Dental Society.

Dr. Renken is dedicated to organized dentistry and continuously growing his — and his staff’s — professional knowledge. He is a member of the Academy of General Dentistry, the American Dental Association, and the Chicago Dental Society. He is also a fellow of the International College of Oral Implantologists.

As a community member and dedicated dad, Dr. Renken is focused on the needs of our community. First in Illinois, and now in Texas, Dr. Renken demonstrates his commitment in various ways. He is a long-standing member of The Hope Institute for Children and Families. He is currently serving the organization as chairmen of the board of directors and has volunteered his dental practice in Springfield as a pilot site for Hope’s Vocational Program. Through this pilot program, the dental practice has been able to meaningfully employ and support a team member with development differences. Dr. Renken is also a member of the Ambassadors of Hope, a volunteer group of business leaders who serve as advocates for The Hope Institute and the children and families it serves. He looks forward to getting involved in local community outreach efforts in Georgetown, TX and continuing his work for children and adults with neurological and developmental differences.


In recent years, Dr. Renken has founded several businesses including a dental practice management company — PracticeWater, a properties company — Renken Properties LLC, and dental practices in Leander and Georgetown, TX. He brings affordable dental coverage to patients without dental insurance through Health Assurance,  a membership plan that offers included services and discounts. His debut book was recently released, titled Dr. Fries-With-That. Dr. Renken’s mission is to assist dental practices to build better health for their patients, staff members, and practices.


Dr. Renken and his family moved to Texas to live closer to extended family members. Dr. Renken opened Renken Dentistry in Georgetown, TX to bring quality dental care to the area. He appreciates the warm welcome he’s received in Texas! He and his wife, Leigh, live in Leander with their four children, Reilly, Miles, Oscar, and Lorelai.
