ARA CEO Guy SylvesterGuy Sylvester

Guy is a former board member of the New Hampshire Chapter of the Indoor Air Quality Association (IAQA), the American Lung Association (ALA) in the Northeast, and Past Chair of the ALA Leadership Board in NH.


Guy was winner of the NH Business Review (NHBR) Business Excellence Award in 2011, and is co-founder of the New Hampshire Mold Task Force, a group which helped to pass SB125 in NH, which is important legislation in support of consumer protection and health as it relates to mold. Guy is a visionary leader and Strategic Contractor at Absolute Resource Associates, helping guide the firm toward market trends that will best serve our customers and the environment. 


Guy has managed environmental firms and projects all over the country before purchasing Resource Laboratories (now Absolute Resource Associates) in 2000 with his wife Susan Sylvester. After helping set the lab up for success, Guy then created the Indoor Air Quality division of the business, seeing a need to help solve indoor air quality mysteries for his customers. His passion for helping people with illness related to air quality led Guy to write a book for consumers, entitled "Mold: Myth or Monster?" which helps homeowners and small businesses in their quest to get information and help as it relates to mold, indoor air quality, and related health issues. 

In his college days, Guy was a wildlife biologist and his attraction to the natural earth and all its creatures is still strong. In his spare time Guy enjoys spending as much time as he can in the great outdoors kayaking, sailing, camping, biking, skydiving and even doing 5K races and triathlons for fun. However, his most pleasurable moments are spent enjoying time with his family, especially his grandchildren.
