Mark Kropilak
Senior vice president of corporate development - i.e. the growth guy - for Aqua America, the water utility holding company based in Bryn Mawr. Under Kropilak's steady hand, the company has morphed from regional company to national player, serving more than 2.8 million residents in more than a dozen states.
And he's not just a salesman: Kropilak, his wife and two teenage sons live in Valley Forge, in an Aqua-serviced area. No Brita water filters at his house: He joked that the water is so pure, "I don't even use a cup."How he got into the water game: Kropilak was first driven by legal aspirations. A western Pennsylvania native, he went to law school at Columbia University. After a stint at the Philadelphia law firm Morgan Lewis, he came to Aqua America as an assistant general counsel. Eventually he realized he wanted to get in on the deal-making; one Villanova MBA later he got a seat at the table. Aqua has expanded into seven states under his leadership.
