Brand experience agency, Avantgarde London, announced two promotions in its senior team. Tessa Mardon will take on the role of head of client services, and Rory Sloan, operations director.

Sloan, previously production director at the agency, will now support MD Stuart Bradbury in the day-to-day operational running of the agency. Alongside this he will direct and control all production, purchasing and internal processes for the agency to ensure that business objectives are met efficiently and effectively.

Moving away from her prior role as business director, Mardon will now focus on building strong relationships with senior clients. Mardon will manage both the client service and project management teams, while continuously developing the agency's brand experience expertise and identifying commercial opportunities with existing accounts to help drive growth.

Mardon says, “Having been with Avantgarde for seven years now, I’m thrilled to have been given the challenge of nurturing and growing our fantastic spectrum of existing clients. The agency has an impressive combination of experienced, passionate people and industry leading brands in our client roster, and I’m excited to be moving into a role that is pivotal to the success of our client relationships.”
