Recruitment & Enrollment Team

Joel Hetelle

Joel is the Site Manager for the All of Us Research Program at UW-Madison. After receiving a Bachelor of Science degree in Biology from UW-Madison in 2014, he moved to Glendale, AZ where his fiancée attended dental school. During his time in the Grand Canyon State, Joel worked on numerous clinical trials and observational longitudinal studies focused on Alzheimer’s Disease. In that setting Joel established a firm foundation in clinical research, learned the value of clear and concise communication, and displayed an aptitude for treating research participants with empathy and respect.

Missing family, friends, and the elbowroom of the Midwest, Joel and his fiancée moved back to Madison in 2018. Joel began working on the All of Us Research Program in June 2018, shortly after its national launch. As a study coordinator, Joel travels around the Madison area and enrolls participants by recording valuable data, like participants’ physical measurements, and collecting biospecimen like blood, saliva, and urine.

You may also see him around town at various events discussing the program with members of the community. If you do, be sure to stop by and ask him about the program, Badger sports, the Cubs, Daaaa Bears, movies, music, or craft beer.
