Before Alvin Flanagan, of Valrico, Florida, bought his own Stratus Building Solutions franchise his life was completely different. He was in the cleaning industry, cleaning his clients’ office buildings. OK, it wasn’t that different — after all, Stratus is a leading green commercial cleaning business. For about 14 years, Flanagan was running his own custodial service that he called Cleaning 101. Obviously, he could have kept doing only that, but his wife, Leah, heard about Stratus Building Solutions, and it intrigued her.
