I was shocked to hear about Zack's passing. I had the opportunity to know Zack from August to November of 2001 while acting as a water sanitation and cross cultural instructor at Tubani So, Mali.

I remember a guy of outstanding character. He was both funny and clever. I know he was smart and he struck me as courageous. If time worked in a different way, I would have been proud to serve with Zack, but as it was, I was proud to instruct him.

This is a real tragedy.
