JIM GARRETTSON

Chief Executive Officer & Publisher

Jim Garrettson founded Executive Mosaic in 2001 in an effort to build an exclusive forum and cross media platform exclusively for top-tier executives in the greater Washington D.C. market. His efforts produced an array of highly specialized internet-based media properties, publications and event driven executive peer groups. Sensing the continued growth of the Government Contracting community and consolidation of the mid-tier companies, Garrettson evolved his models and efforts to strategically pursue this key market segment. Today, he has created a prestigious series of private networking communities for top executives, and serves as publisher for the growing number of Executive Mosaic online and print media outlets.

In addition to Executive Mosaic, Garrettson also founded the Potomac Officers Club (POC) as a 501(c) 6 non-profit organization whose mission is “to weave an executive fabric that benefits our local business community. ” That organization and the associated e-magazine he founded in 2003 (ExecutiveBiz) served a pronounced need at the time for connecting the Washington business community.

Subsequent organizational founding’s also include GovConWire – a daily news wire and reporting organization dedicated to Government Contracting, GovConExecutive – an organizational who’s who in Government Contracting, The New New Internet – an ongoing effort that tracks the technology that supports the government’s leading edge IT initiatives and ExecutiveGov – which tracks the key government executives that make the decisions which most strongly impact the market segment of Government contracting and included current, transitional and former government executives.

A serial entrepreneur and veteran of the fast-growth technology and telecommunications industries, Garrettson is also Founder and President of TownHall Teleconferencing, and earlier served as EVP of Sales and Marketing at Net2000 Communications, SVP of North American Sales for Satellite based streaming media provider Cidera, President of Teleglobe Business Solutions, SVP of Sales at Qwest Communications where he ran the National General Business sales force and various positions with MCI Telecommunications. Garrettson is a graduate of the University of Hartford’s Barney School of Business and serves on the advisory board of the George Mason University’s College of Science.
