The son of two lesbian mothers, the 20 year-year-old University of Iowa engineering student had no idea that his heartfelt testimony before the Iowa Legislature would spread like viral wildfire, and land him on the Ellen DeGeneres Show.

Two days after he testified a YouTube video of his testimony went viral, garnering two million views with millions more via Facebook, Twitter, national and international television and other online media. After appearing on numerous television programs, and his testimony airing on MSNBC, ABC, CBS and CNN, Zach has written a book My Two Moms and is now touring college campuses with a game-changing lecture called "What Makes a Family?"

He shares a story that has never been told, and offers a fresh bold perspective on an always contentious issue: gay marriage.
