Tim was the Washington State boys ODP coach in the early 1990s, then stepping up to Men's U23 ODP state college coach & Washington State Women's ODP Asst coach.

In 2007, Tim moved to Harbor Premier Soccer Club and into the girls program. Since then Tim has primarily coached mostly at the girls older ages with great success. In 2015, Coach Duffy was able to lead the Girls 2000 team from division 3 to division 1 in one year.
