Kevin W. Corcoran

Kevin Corcoran – Retired 29 Year Syracuse Police Department Veteran.

As a young police officer and father of two, I was looking to make a positive connection between a job I loved and family living. I began taking leadership and team building courses leading to the building of rope courses and the facilitation of community groups. I made connections between community, school and business leaders to generate customers to explore and experience my enthusiasm for these programs. As interest piqued, my clientele diversified. My style and focus branched out. This hobby provided a healthy balance between my police duties, family and pursuit of purposeful living. My goals and life experiences continue to evolve and bring true meaning to the joy of life.
