Stories from a few of CVSan’s 4R Star Business Employees!
Samantha RJQCC 192 x 256
R & J Quick Clean Center
Samantha collects left-behind hangers for reuse at the store and helps donate unclaimed clothing. She spilled bleach on her work shirt so she tie-dyed it to give it new life. Far out, Samantha!

Joe Smith LCPM 192 x 256
Lake Chabot Public Market 
Joe designed a drought-tolerant landscape using repurposed rocks and plants and maintains the waste stations for the market. How’s that for a green thumb?

Kim-Louise FPC 192 x 256
First Presbyterian Church of Hayward
Kim-Louise is leading the effort to convert from single-use disposables to reusable dishware. She also prevents food waste by incorporating leftovers into meals. Sounds yummy!
