Prior to starting his own venture Mark spent 20 years in the Building Materials industry with CertainTeed and GAF Materials Corporation.  He moved from Field Sales to the position of Vice President of National Account Sales with GAF Materials Corp. Mark was responsible for the sale of all GAF products from Roofing, to Ventilation to Vinyl Composite Decking into the Home Center retail, Line yard and 2-step channels of distribution, with responsibility for a division just shy of a billion dollars annually. Mark managed the National Account group for many years and during that time he established strong working relationships with all of the major players in the industry. These are relationships that continue to grow at MDE Sales as they respect his drive, his direct style but most importantly his ethical nature. Mark's word can be counted on, and that is ultimately what the customer's want, someone they can trust whose word is his bond. 

MDE Sales started when it became apparent that there are many companies that need the expertise of a seasoned professional in National Accounts, but don’t want to or can’t add a person of that caliber to their staff permanently.  MDE Sales provides companies with the opportunity to have a highly professional National Account organization at their disposal to help them grow their business.
