***Before I went off to West Point as an 18-year-old, I had never left the city of St Louis and never flew on an airplane.  Since then, I’ve been blessed to travel to – by last count – 123 countries around the world and lived for more than 15 years outside the US.  Our family is extremely close, we have two sons and now five grandson, and both our sons and one of our daughter-in-laws have also served in the military.  My favorite daily activity is cycling and exercising, but I also like happy hour with my wife, Sue.  Favorite thing about teaching at Crummer is the interaction with young people, and helping them face the challenges of the world (and avoiding the many mistakes I made!)
