Mr. Zaccheo has been married to his soul mate from Australia since March of 1998 and recently has become a father of a beautiful girl.  An “unhealthy” fan of the University of Michigan sports, Mr. Zaccheo likes to spend in the outdoors, especially Yosemite National Park and at his family’s cabin in Arnold, California.  Another major part of his life is traveling outside of the US.  He has been to Australia, Italy, Holland, Spain, Austria, Germany, Fiji, and Michigan.  GO BLUE!
