Bob Sherwood

Bob Sherwood,

Vice President

Bob has always enjoyed hiking, walking the beach and just exploring nature. Milwaukee is very grateful to have our wonderful County Park System for walks as well as golfing. However, Wehr is a hidden gem within Whitnall Park. I became a volunteer in the Wheel 'n Chip Society 5+ years ago to continue being outdoors. This far different from my preretirement  professional career in human resources where I managed employment, compensation and labor relations. I earned a bachelor's degree in Labor Relations from UWM and held senior professional certification in SHRM organization.
