Dieterle, who owns an accounting firm and also coaches club soccer and runs camps, has a house with his wife, Patti, in Rehoboth Beach, Del., and plans to pursue coaching opportunities there.
Dieterle's record stands at 172-24-21 with three IAAM championships after Saturday's semifinal win, and he has coached several players who went on to enjoy Division I college careers and beyond. The most notable is 2008 Archbishop Spalding graduate Christine Nairn, who went on to play at Penn State and is currently on the U.S. women's national team roster.
Dieterle turned the Spalding program into an area powerhouse that also has received national recognition in past years. The Cavaliers reached No. 1 in the country in the NSCAA and ESPN polls on two occasions in two previous seasons.
"It's been an amazing trip. I've really enjoyed coaching with my assistant Bob [Wagner] and we've just had a blast working with the girls," Dieterle said. "We defined our goal and asked: 'Where do we want to be?' And we wanted to be the best that we could and we thought that included being champions of the league. So right away, we set out to play the best teams we could because we thought the only way we would get better was to play against the better teams."
