Name: Ana Maria Chadwick

New title: CFO, Insulet

Previous title: CFO, Pitney Bowes

Insulet has appointed Ana Maria Chadwick as CFO, filling the vacancy that Wayde McMillan created by moving to 3M’s healthcare business last year, the company said Wednesday.

McMillan was part of a clutch of executives who left medtech companies last year to take up senior positions at 3M’s healthcare unit, which is set to split from its parent company on April 1. When McMillan left, Insulet made Lauren Budden, its chief accounting officer and controller, the interim CFO and treasurer and began looking for a permanent successor.

The search led the insulin pump manufacturer to Chadwick, who spent the past three years at the shipping and mailing company Pitney Bowes. Chadwick gave Pitney Bowes her resignation last week but agreed to stay on until April 21. The CFO will start at Insulet on April 22.

Insulet CEO Jim Hollingshead called Chadwick “an experienced public company CFO” who is known for “her insight, intellectual agility, and compelling and collaborative leadership” in a statement. The appointment follows a search that considered internal and external candidates.

“We have internal candidates who are really strong, including Lauren, and [the] early look at the market looks really promising,” Hollingshead said on a November earnings call. “We want to move as quickly as we can because we want to get to some stability there. But we're very confident we'll get the right person in the role.”

Chadwick spent more than 27 years at GE before joining Pitney Bowes. At the shipping and mailing company, Chadwick refinanced the terms on about $1.5 billion in debt and sought to use automation to improve margins. Insulet is in a different business than Pitney Bowes. Efforts to expand margins while investing in new products are a focus of Chadwick’s new employer.
