I have been a high school math teacher and part-time administrator since 1976 in private schools in Chicago. I have always been interested in space exploration since the first Mercury astronauts were launched in the 1950s. I enjoy sharing my enthusiasm and knowledge of space with anyone willing to listen. I am married and have two teenage daughters. My wife does not share my enthusiasm for space but supports my work. The younger daughter follows my presentations faithfully. The other one is an artist.
