After a season of questioning and spiritual exploration during her college years, God revealed Himself in powerful and personal ways in early adulthood—especially during her journey to motherhood—drawing her back into a vibrant faith.
Krista and her husband, Pat, have two young daughters, Norah and Skylar. Since becoming a mom, Krista has embraced the stay-at-home life, pouring her creativity and care into her family.

Now retired, David previously worked as a financial advisor to local governments throughout Wisconsin. He is widowed and remarried, and together with his wife shares a beautifully blended family of six children, along with many grandchildren and great-grandchildren.
