MicroMass, like most agencies, has dealt with a mixed bag of account news this past year. According to Jay Bigelow, agency president, it proves that agencies need to build flexibility into their planning. MicroMass posted 20% annual growth in 2008, the fourth year in a row it has done so. MicroMass just picked up a new client in the hypertension space, which Bigelow prefers not to name. Earlier this year, another new assignment came from Acremex. In keeping with its flexible approach, the agency has judiciously added staff in the digital and creative areas. Among its existing relationship-marketing accounts, the agency has been running the Committed Quitters program for GlaxoSmithKline Consumer Health's smoking-cessation franchise for 15 years.
