Lew founded Mason-Grant in 1986 as a technical research and development consultancy. Through his writing, speaking and training, Lew specializes in explaining complex issues especially those related to moisture -- to professionals and laypersons in understandable, accessible ways. It's hard to believe Lew last joined us almost 4 years ago and we are looking forward to his return with an update on what's new in IEQ, disaster restoration and building science. We are particularly interested in Lew's thoughts about the Indoor Air 2011 conference where it seemed he was everywhere asking probing questions plus giving a well received presentation.
