Professional Passion: What drives me is the desire to serve my community and my department

Best Part of My Job:  It’s seeing the role our agency and officers play in the community and the public support it generates. Very few police departments receive this type of support from their residents, and we are appreciative and proud to serve them.

Personal Interests: Family, camping, and snowboarding. Just being able to watch my kids’ activities is a nice vacation for me.
