Ballard Spahr has mined the Rocky Mountain foothills for its latest outpost, adding three corporate partners in Boulder, Colorado, focused on emerging growth companies.

Carin Cutler, Nathan Seiler and Steven Dupont are joining the firm from Gross Cutler Seiler Dupont, a boutique they formed in 2010. The trio handles corporate and securities matters, mergers and acquisitions, licensing and strategic transactions for startups and venture capital clients.

"It's just a confluence of so many things we've been trying to look for," said Ballard Spahr chairman Mark Stewart said.

Brian Pinheiro, chair of Ballard Spahr's business and finance department, said Cutler, Seiler and Dupont were "known quantities" in Boulder with the ability to use their skills regionally and nationally.

"We really wanted to make a splash in Boulder," Pinheiro said.

Seiler said they liked Ballard Spahr's national footprint and focus on corporate and securities work. He said joining the firm offered the opportunity to regain the resources of a large law firm while preserving the personalized client service they emphasized at their small firm.

"It's an environment that will allow us to preserve our ability to maintain close and strong, long relationships with our clients," Cutler said.

Their clients—about half of whom fall into the emerging growth category—include life sciences, medical device, software and natural products businesses, ranging from the early stages of development to public companies.
