Employees and family members from The Sigma Group explored, scoured and picked up trash in the habitat surrounding their office building in the Menomonee River Valley as part of the Milwaukee Riverkeeper’s 22^nd Annual Spring River Cleanup on April 22 in Milwaukee.

Filling bags of litter along with other volunteers and families at events like the Annual River Cleanup is a fun and meaningful way for Sigma staff to collaborate and connect. 2017 marks Sigma’s 10^th straight year working on the River Cleanup, which is just one of several activities where Sigma supports the environment and Milwaukee community.
