Elliot Dalberg,
Principal, Executive 
Media Director

Elliot is a marketing and media professional specializing in media research, planning and effectiveness measurement. Elliot feels strongly that the right media thinking goes a long way toward making good creative successful. Simply put: regardless of how great any campaign’s creative executions might be, if the creative isn’t delivered to the right audiences, in the right media, at the right time, it’s unlikely to succeed. Great creative is founded on a great media program. That’s where Elliot comes in.

Prior to joining forces in the agency business with David, Elliot served in a variety of senior marketing executive positions with major retail corporations, including print advertising director for the Macy’s/Bamberger’s organization. With responsibilities for some $55 million in annual advertising expenditures — much of it in direct marketing — Elliot came away from the experience steeped in an appreciation for the value of data management and analysis as measurably effective means for honing targeting and messaging. The result has been leadership work in the development of our abilities to empower client direct marketing with increasingly predictive success.

Debby Garman
Senior Vice President, Media

Debby got her start in advertising with Mid-Atlantic Coca-Cola’s in-house ad agency in 1983.  The agency handled major metro markets in Maryland, Washington, DC, Pennsylvania and Virginia.  She not only worked in the media planning/buying capacity, but graduated into running all promotional activities with the crown jewel of Coke’s events being Hands Across America.  Debby was in charge of the youth marketing effort and worked with Congressman Connie Mack of Florida to bring a group of students to the Washington metro area to participate in the festivities. 
Debby took her bubbly personality and headed west to Oklahoma to join All-American Bottling Company’s in-house ad agency.   The company’s main brands were RC Cola, 7-UP, Dr. Pepper, Big Red and Orangina.  Along with media planning/buying tasks, she flexed her creative muscle by including promotional copywriting and mascot duties to her resume.  (Her first acting credit was as the 7-Up “spot”)
Later she returned to DC to work on several high profile accounts, such as Crown Books, Trak Auto, Papa John’s, TJ Maxx, Jim Koon’s Automotive, Arby’s  and Consolidated Edison…aka Con Ed, working with ROI principal David Nellis.  During this time, Debby was able to secure such sponsorships for her various clients with the New York Mets,  New York Giants , Washington Wizards, Washington  Capitals, Washington Redskins, and various socially conscious partnerships, such as breast cancer awareness, missing children and youth violence prevention.
After a long stint in consumer marketing, Debby was lured away to the world of political advertising.  Political agencies in DC were tired of the cookie-cutter approach to advertising, so Debby brought a new way of reaching potential voters.  Given her consumer background, she was adept in finding the best way to reach elusive audiences.  Knowing that Debby has handled the diversity that she has – from retailers, wholesalers and manufacturers to government agencies, defense contractors and presidential hopefuls. David brought her to ROI.   Whether it’s via programming not normally used, the Internet, blogs or social media, Debby knows how to reach a client’s target audience and reduce spending waste.
