In the 15 years since Stuart Grant and Jay Eisenhofer started their own law firm, Grant & Eisenhofer has grown from four attorneys to almost 75 in three offices.

That $1.6 billion settlement, announced in May, involved alleged ­illegal marketing of the anti-­seizure drug Depakote to children and geriatric patients.
