Last year, Brahm saw turnover increase by over 14% to £17.5m, giving the agency a 50% growth in revenue over the last three years.
Brahm wins last year included Bradford Centre Regeneration, National Express Group, which tapped it to launch the largest rail ticket offer yet made in Britain, and pet store chain Pets at Home.
The agency also acquired the food-service marketing specialist Teamwork Marketing.
The four new associate directors are: Thea Mallet, head of design and digital; Paul McGann, head of promotional marketing; Robin Horsfield, head of research; and David Henzell, head of production and operations.
John Morgan, joint managing director at Brahm, said: "These talented individuals have contributed considerably towards the growth and success of Brahm. Each has already demonstrated outstanding results for our clients.
"I am fully confident that they have the insight to inspire even greater results in the future. Few communications agencies can truly offer expertise across the breadth of marketing specialisms as we do at Brahm -- we will ensure that clients continue to reap the benefits."
