Lisa Marchewka is a Vice President & General Manager | Board Member at Owens Corning. Colleagues describe them as "Lisa is an outstanding business developer, strategist and executive, with knowledge of and access to the full spectrum of water treatment industries. Her effectiveness draws from her hands-on experience with sales and marketing, her maturity as an executive, her impressive technical competence and her delightful demeanor. At Oasys, we worked together on an extremely challenging problem of developing and launching a new water treatment technology platform. Lisa drove the strategic process, bringing in essential outside resources and information, forging consensus among her managment peers and making the effort positive and fun. I recommend her without reservation for an executive role in any water company and have no doubt that she could flourish with equal brilliance in other industries." and "I have known Lisa, both professionally and personally for nearly 15 years. In that time I am not aware of anything she has set her mind to that she has not accomplished with ingenuity, dedication, and creativity. She is, as they say in the parlance of her native New England, “wicked smart” and, more importantly, she has the solid grounding and humility to not let it go to her head. In short, if she tells you she is on it; consider it done and done well."
