Who Are We

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 providing a personal, high-quality service.

Since its formation in Jersey, Channel Islands, we have advised a broad range of internationally-focused corporate clients on their communications strategies in support of marketing and business plans.   

Placing an emphasis on building strong relationships with clients, acting as an extension to their internal teams, we have advised many businesses consistently for ten years or more.  While many of our clients have their headquarters in Jersey or Guernsey, our consultancy services are global, extending to London, Luxembourg, the Isle of Man, Ireland and Gibraltar, to the Cayman Islands, the BVI, and the US, to Hong Kong and Singapore.
