Thielen Foundation

Since 2021, the Thielen Foundation has stood behind BIO Girls and the girls we serve.

Founded by Adam and Caitlin Thielen, the Thielen Foundation exists to help kids reach their full potential. That belief is at the heart of BIO Girls, too. Every girl deserves to know she belongs, she matters, and she is capable of far more than she imagines.

A Shared Belief in Kids

The Thielen Foundation believes in the power of movement and community to shape young lives. At BIO Girls, girls build self-worth, resilience, and healthy relationships through mentorship, connection, and moving their bodies together.

Partners in the Mission

Year after year, the Thielen Foundation’s support helps us protect and strengthen the mental health of adolescent girls. We are deeply grateful for a partner who shows up, stays committed, and believes in the next generation as much as we do.

Thank you, Thielen Foundation, for investing in girls who will change the world.
