Guided by values instilled early in life—integrity, selflessness, and a commitment to excellence—Dr. Conley found his calling in a career where he could make a meaningful impact on others while expressing his lifelong passion for art. His journey into dentistry began during his time with the 137th Special Operations Medical Group (SOMDG), where he worked closely with dentists and medical professionals who inspired him with the idea that dentistry is an art form—a concept that immediately resonated with him.

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.
