Adnams created the marketing role and appointed Curzon with a view to further expansion, following its first national advertising campaign in August last year.
Curzon will report to Adnams sales and marketing director Andy Wood.
He will be responsible for a marketing strategy for the brewer's portfolio of brands, which include Adnams Bitter, Broadside Strong Original and Suffolk Strong Bitter.
He will also oversee marketing for Adnams' estate of 84 pubs across East Anglia, as well as its wine business.
Curzon joins the company in February following four years at the LTA as director of marketing.
His move to Adnams marks his return to commercial marketing. Before joining the LTA, he was marketing manager for Nescafe.
Curzon said: "I was always going to return to commercial marketing; it was just a question of when. I joined the LTA to attain certain goals, which I believe have been reached. This move is a great opportunity for me. Adnams is a progressive company with ambitious growth plans."
During his time at the LTA, Curzon has overseen the rebranding of the organisation in collaboration with Interbrand. The corporate identity, unveiled in September last year, freed the LTA from its staid, old-fashioned image.
Other LTA initiatives in which Curzon was involved included the introduction of a range of child-friendly projects such as 'Mini Tennis', which was developed to help find the UK's next Grand Slam champion.
He was also instrumental in securing the promotional partnership of Procter & Gamble's Ariel.
Curzon said he was hired by the LTA to support the organisation's vision of making the UK a successful tennis nation. It is unclear whether the LTA will appoint another director of marketing.
Adnams' first national campaign broke last year, with creative by Campbell Doyle Dye. The 48-sheet poster execution depicted a range of rugged seaside scenes based on the town of Southwold, where the brewery is located.
CDD picked up the brewery's £1m advertising account at the beginning of 2003.
