Bill Sheetz About Me Pic

Bill Sheetz, President

Bill founded Lake Cook Exteriors Inc in 1987.  However, he began in the trades as a siding installer for a contractor where he gained his expertise in exterior remodeling.  Bill was promoted into a Sales position in 1978 where he found his “nitch” helping homeowners find solutions to their remodeling needs.  Then in 1987, Bill along with his wife, Karen, partnered up in their joint venture called Lake Cook Exteriors.  The family owned business has now expanded when their son, Nolan Sheetz, joined the staff in 2014 with plans to carry on Lake Cook Exteriors Inc. Bill is an avid sports fan, enjoys spending time with family and traveling.
