MARKETING

First Aid for Ad Agency: Health care is the industry that’s been good lately to ad agency Forsythe Marcelli Johnson. The company, based in Newport Beach, said it has hired five people in response to a 33% increase in billings during 1992.

Among the newcomers is an account supervisor, John Sullivan, hired to work with Northern California medical-device makers, the company said. He had spent 15 years working in sales and marketing with Lederle Laboratories.
