I was honored to present the Commencement Address to the Class of 2015 at my High School alma mater, South Lewis. Congratulations to all of the graduates! On a side note, I didn't know my high school friend, Minnie (Bronson) Goss, would be in the audience that day.

He is a husband and father, and the author of the new, heartwarming book Napkin Notes: Creating A Daily Connection With Those You Love, in which he features lunchbox notes he's written to his now teenage daughter throughout his diagnosis.

Garth is interviewed on CBN, the Christian Broadcasting Network, for the 700 Club Show. CBN is located in Virginia Beach, VA. Terry Meeuwsen is the interviewer.
