Gretchen brings more than 23 years of experience in Christian Education. For 16 of those years, she worked as an admissions director, partnering closely with families and school communities to support enrollment, access, and student success. Gretchen offers personal perspective on the tax credit program, having utilized it to give her own two children a private Christian Education from Kindergarten through high school. Tax credit scholarships provided a path she never thought possible for her children’s education, and that experience continues to shape her commitment to helping other families access similar opportunities. Now an empty nester, Gretchen enjoys spending time with her husband, traveling, working in the yard, and discovering new hobbies during this season of life. She and her husband have also been active members of the same church since moving to Arizona in 1987.
