Tim is a firm believer in giving of his time and services to the community and charitable organizations.  Tim has served on the boards, and in officer positions, of the Young Lawyer’s Division of the Bar Association of Metropolitan St. Louis (Recipient of Award of Merit), the Real Property Law and Employment Law Committees of the Missouri Bar, Jefferson City Rotary West (President), University of Missouri Alumni Association (President), Special Learning Center Foundation (Past President and current Board member), Capital Soccer Club (President), Jays Soccer Boosters (President), Lady Jays Soccer Boosters (President), Boys and Girls Club of Jefferson City (President), HCJ Foundation (current board member), as well as volunteering for numerous events and activities.
