Dianne began her career in banking, advancing to Vice President of Bank of New York and M&T Bank. She married her husband John, whom she met in high school, and they have two young adult sons. Although it looked like she had all she was striving for, inside she felt a longing for something more. In March 2001, two women came to her office looking for a business loan and ended up sharing the Gospel with her. Later that night, Dianne committed her life to Jesus. That encounter changed her life, and her deepest desire is to share the Good News of salvation through Jesus Christ in the power of the Holy Spirit! She longs to see revival in the Catholic Church and across the world through people personally encountering Jesus. Dianne serves as ChristLife’s Director of Mission Expansion, and as conference speaker, and teacher, and co-author on Sharing Christ series and Share Christ book.
