About Us

Tandem Mentorship Program gathers people of faith to mentor youth facing adversity in the Chippewa Valley and surrounding areas through Christ-centered, guiding relationships. Tandem was birthed out of seeing a need for more caring adults in the teen’s lives that we were volunteering for in 2013. These youth that we were working with were the ones that fell through the cracks. We were able to build trusting relationships with them and had the opportunity to see the potential in all of them. One of our favorite authors and motivational speakers, Josh Shipp says it best, "every child is one caring adult away from becoming a success story."

A few years later in Jan 2016, we had the privilege to start Tandem underneath an organization called 513FREE, which is a local worship and prison ministry named after the Bible verse Galatians 5:13. You can learn more about this ministry at 513free.com.

Since 2016 we have had 38 community mentoring relationships, and 10, soon to be 13 in-school mentoring relationships. After seeing growth and progress in our program we decided to become our own entity and pursue our non-profit status. We can thankfully say that in Sept 2018, we were granted our 501c3 status!
