Years before Maura Healey embarked on a public service career, she was a junior attorney in the litigation department of an international law firm, representing private clients. It was a job for hard workers, team players, and people eager to learn, but didn't come with the spotlight, power, and influence Healey inherited when she was elected attorney general. "There are not a lot of Perry Mason moments if you're a junior or midlevel associate," said Jonathan Shapiro, Complex Litigation & Dispute Resolution partner in San Francisco who previously worked with Healey, to The Boston Globe. "These are difficult jobs. There's a lot of blocking and tackling. The Perry Mason moments are few and the senior guys and gals get them."
