Executive Team and Board of Directors

Mark Mauk, Founder & Board Chair

Mark became aware of Guiding Star Project though activities associated with the Marshall County Culture of Life Committee.  He was inspired by how Guiding Star Project services support women, men, and families in living out their lives in the way God intended.  As a relatively new Catholic (he joined the Church in 2001) he was happy to see that the Guiding Star Project mission is in alignment with the Catholic Church’s teachings on family and fertility.  Looking at this community and finding no organization that is focused on assisting women and families, Mark felt this was a way to actively bring these teachings to the community by helping others to live them, something that he wished he had access to earlier in his life.  Although starting a non-profit like this is a little out of his comfort zone, it also became a calling as he found that both his wife, Mary and he was drawn toward the formation of Guiding Star Marshalltown.  We know that those who become involved with Guiding Star Marshalltown will be blessed just as many others have been by the Guiding Star Project Affiliates who provide these services in their communities.

Teresa Ingold, Vice Chair

After raising three children in the church and a career in the corporate world, Teresa Ingold’s old life ended abruptly when she was diagnosed with breast cancer. With love and support from her family and blessings from our Lord she has not only survived the past six years but has thrived.

After 38 years together, that experience led Teresa and husband, Leon, to start a fulfilling business in Marshalltown, while managing a nonprofit counseling service for seniors. But she felt that there was more she could do to serve our Lord, so she opened her heart to all possibilities, and He sent Guiding Star Marshalltown into her life.
