Who we are

Established in 1994 by public relations consultant and former journalist, Mike Sunier and experienced marketing strategist Marianne Sunier, the agency is an independent, family owned business committed always to a highly personal service.


Since formation in Jersey, Channel Islands, we have advised internationally focused corporate clients on communications strategies in support of business development and marketing plans.
