Brendan is a graduate Mechanical Engineer, (University College Dublin, Ireland, 1965). Prior to his arrival in to the U.S.A. in 1986, Brendan spent almost 10 years working in Saudi Arabia, initially as a field superintendent. Later activities in Saudi included a 6 year spell as general manager for a Saudi family group of companies with activities in real estate, metal fabrication and petrochemical related mechanical construction. 


The initial 13 or so years in the US were spent in a partnership with a Philadelphia developer, operating in the Pre-Engineered Metal Building market. The launch platform for this consisted of flex building shells built for speculative real-estate development. The partnership morphed into a supply-erect service to local GC's, CM's and some other building owners. The Flynn PEMB partnership was based laterally on a Butler Building dealership agreement, signed in August 1988. Through that relationship, Brendan became familiar with the Butler organization on many levels and as a result, in October 1999, Brendan was appointed independent Sales Representative for Butler Manufacturing Roof Group. In that time Brendan has become the leading independent Sales Representative for Butler in the U.S.A.

Prior to opening this new business, Nigel spent over thirteen years working in a number of divisions of Kingspan, a $2.5 billion turnover construction products manufacturing company in Ireland, Canada and the U.S. The past five years have been spent primarily calling to the metal industry sector, specifically to metal builders/contractors, roofing sub-contractors, and to architectural firms pursuing business development opportunities. 

When Nigel is not working he is spending his time with his wife and five children in Annapolis MD. Nigel has a BA in Business from the Irish Management Institute of Dublin, Ireland and is a Construction Document Technologist CSI CDT.
