Besides caring for patients full-time, Dr Renken continues to create innovative solutions for the dental industry. As dentists and their teams are now providing a range of advanced procedures, he wanted to add a structure that would lend itself to consistent, and reliable outcomes for patients. Maximizing efficiency and organization in the dental care delivery system, Dr Renken invented and patented the Drop Delivery System where a dental practice can routinely provide any procedure in any dental setting. More recently, Dr Renken has been testing an innovative scheduling and rewards automation software called CareSchedule. The software is meant to optimize and simplify dental care appointments for patients and their dental practice. Currently testing, it is set to launch summer of 2020.  CareSchedule and the web-based patient subscription management platform, Health Assurance Plan, are part of the Springfield startup incubator Innovate Springfield.

The sum of these efforts has become the Smile From Within Growth Platform. The goal continues to be creating greater health for team members, patients, and practices.Dr. Renken and his wife, Leigh have four children: Reilly, Miles, Oscar, and Lorelai, and a dog named Stella.
