He left the family business in 1984 and went to work for Jerome Schmelzer & Associates, doing advertising and public relations account and creative work. Wanting "to do his own thing," Golub started his own photography company in 1988.

Golub specializes in editorial photography. Current editorial clients include Crain’s Cleveland Business, Smart Business Magazine and Cleveland Magazine. He has also created imagery for USA Today, Newsweek and The Plain Dealer as well as a number of other corporations and nonprofit organizations, including The Cleveland Clinic, City of Beachwood, University Hospitals, Bendix Commercial Vehicle Systems, The Albert M. Higley Co., Hathaway Brown School, Beachwood Place and The Gathering Place.

A self-described computer guru, Golub uses seven computers — three laptops and four desktops in both Mac and Windows platforms. It would be natural for him to gravitate to web site design with its inherent manipulation of imagery. He has designed web sites for such clients as The Chesterfield Steel Sales Co. (www.chesterfieldsteel.com), PLAN of Northeast Ohio (www.planneohio.org) Donald L. Barr & Co. (www.dbhomes.info), SporTech (www.sport-tech.org) and The Apartments of the Pointe at Gateway (www.pointeatgateway.com).

Marc has provided digital technology training for such clients as the Cleveland Bar Association, Visconsi Companies and Cleveland Restoration Society.
