This is my friend Tiffany
Tiffany Gelpi is the Founder of CHANGE Collegian Network, a ministry which sets up and supports biblical evangelism training fellowships on college campuses. The student led fellowships provide training in evangelism and apologetics, and equip students to share their faith biblically, effectively, and boldly with other students and even their professors! She is also creator of CCN Radio for college students.
