Referring to his performance as Claudius in the Commonwealth Shakespeare Company's tenth anniversary production of Hamlet, the reviewer from the Boston Globe said,"Lyman's transformation from confident king to Nixonian cover-upper is a model piece of acting." He was subsequently nominated for an Elliot Norton award.

Since 1998, Will has been closely associated with the Commonwealth Shakespeare Company where he has performed Brutus in Julius Caesar, Prospero in The Tempest and Claudius in Hamlet. He is currently Chairman of the Board of Trustees.
