New Community Service Initiative at INTERRA

Humanitarian Service Project Flyer for DonationsSupraja Reddy, of INTERRA, has a son who is with the Boy Scouts of America and looks to fulfill his scout oath and to become an Eagle Scout. In order to accomplish this goal, he has decided to complete a service project that would benefit the Humanitarian Service Project (HSP) of Carol Stream. INTERRA’s Sanjeev Bandi, Anshu Balekai, and Ashok Guntaka have already assisted his project by fixing the front sign and building a retaining wall around the sign. INTERRA, inspired by the overall goal of Supraja’s son has decided to extend our efforts in contributing to the HSP. INTERRA has a donation bin centrally located in our office, accessible to employees who wish to drop off their donations. HSP is asking for facial tissue, paper towels, toilette tissue, dish washing soap, bath soap, hand soap, shampoo, and oatmeal. INTERRA highly encourages employees to make a donation from the list above as the items from the bin will be collected and transported to HSP at the end of the month, each month.
