MGH was founded in 1995 by President Andy Malis as a traditional advertising and public relations firm.

Since then, the Owings Mills firm's capabilities have expanded to include advertising, public relations, media planning and buying, creative design and production, interactive (design, development and marketing), mobile, market research, direct response, relationship marketing and social media marketing.

With more than 80 employees, MGH works with many well known Maryland brands, including MASN, Ocean City, Old Bay and Smyth Jewelers. It recently expanded its relationship with McCormick & Co. Inc. by providing a variety of marketing services for its World of Flavors store at downtown Baltimore's Harborplace.
 
Earlier this year, MGH launched a “Make It Big" contest to award one small business in Maryland a free billboard designed and placed by the agency. The Charm City Roller Girls won and the female roller-derby league's billboard can be seen on Interstage 95 South, just before the Baltimore Harbor Tunnel and O'Donnell Street exit. The billboard will stay up for one month.
