Board of Governors

David M. Sylvester, PSP


President, 3SE, LLC

Dave Sylvester, PSP, is President of 3SE, LLC, of Sarasota, Fla. He has been in our industry for 18 years and joined DHI in 1997. He was elected to the Board of Governors in 2015.

Dave holds a bachelor’s degree in mechanical engineering technology from Purdue University and an MBA from Purdue’s Krannert School of Business, as well as the Physical Security Professional (PSP) designation from ASIS.

From 2004- 2007, Dave led Ingersoll Rand’s Security Technologies team as President Americas, which included both the commercial and residential markets. He left the industry for four years, but eagerly returned when presented with an opportunity to lead ASSA ABLOY’s sales and marketing teams as President DSS. In that role, he created demand with all influencers, introduced BIM and sustainability to the market, launched many new EAC products, and increased the coordination of the mechanical and electronic sales and support teams.

In 2014, Dave launched a brokerage business focused on the physical security industry’s continued evolution. The goal is to work with CHDs, integrators, and manufacturers as they consider mergers and acquisitions as either growth or transition/exit strategies.

Dave and his wife Michelle have been married for more than 30 years and have two children.
