The firm was established in 1978 as a partnership between James McDonald and Darryl Myers. Bryan Ashenheim and Michael Alberga joined the partnership shortly after. On James McDonald’s retirement in 1985, the firm changed its name to Myers & Alberga.

In March 2009, the firm was restructured on the retirement of Darryl Myers (who remains a consultant to the firm) and Bryan Ashenheim from the partnership. Richard Thorp and Ruth Hatt joined the new partnership, along with Melanie Myers-Khouri and the firm was renamed Thorp Alberga. The firm has been expanding steadily since and now comprises 10 partners.

The firm opened its Hong Kong office in 2009.
