Kingston Smith

Formed in 1923, Kingston Smith has grown to its current position through organic growth and mergers, and is now the largest non-national firm. It has more than 400 people, including 47 partners, based in six offices in London and the South East. And it punches way above its weight, thanks in no small part to senior partner Michael Snyder who is one of the best-connected accountants in the City.
