About Our President and Owner


Barnett Gershen is the owner/CEO of Gershen Consulting, LLC and specializes in business advisory services.


Prior to becoming an independent consultant, Mr. Gershen gained invaluable experience as Chief Executive Officer and co-owner of Associated Business Services (ABS), a $120-million service firm that consistently ranked in the top 5% of like companies in the US and achieved margins higher than industry standards.

Mr. Gershen is qualified by multiple academic degrees and 30 years experience in executive management roles.  He is an innovative leader, with appreciation for strategic alliances, particularly in applying technological advances to enhance and expand market presence.  He was also responsible for generating a client list of domestic/international Fortune 500 companies.  He implemented unique growth strategies that enabled successful transition from a local business to a national company within a highly competitive, tight-margin business. Simultaneous with the sale of ABS, this national service company became part of a $230-million structure with 13,000 employees nationwide - the 9th largest company in the field.

He is the son of Margie Abrams, who began Associated Building Services (formerly XGI Services) in 1945.  As a young widow with three small children, her sheer determination provided the basics for a very small janitorial service. Her integrity was her calling card. She built the business up to annual revenues of $10k, at which time Barnett stepped up to the helm.

As President in 1975, Barnett (Barney to his friends) implemented growth procedures that would make The ABS Companies one of the largest, most profitable maintenance companies in the U.S.

When the company sold in 2004, it employed over 13,000 employees across the nation with revenues of $230 million.

Barnett is now lending his hard-earned experience to friends and associates.  He believes that this is his opportunity to pass on what contributed to his success.  He is endeavoring to build the same hopes and dreams in a new generation of business owners.
