Leo served two wartime military terms as a United States Army paratrooper.  He was placed in a position of leadership early in his military career where he trained other service members to properly parachute and land safely from an airplane.  After his military service Leo became a police officer and served in South Texas and later moved to Sherman, Texas in 1969 where he served with the Sherman Police Department for a number of years.  The remainder of his career was spent in service at the Sam Rayburn Memorial Veterans Center in Bonham, Texas.  Leo worked very hard all his life, often working two jobs at once to provide for his family of growing boys, instilling in them the value of an exemplary work ethic.
