Nuun, the maker of portable, electrolyte hydration, announced the hiring of Casey Otley as chief financial officer.

Otley has 20 years of varied financial experience, most recently at T-Mobile where he held senior finance positions in treasury, investor relations, accounting and financial operations. During his 14 years at T-Mobile, he participated in the company's growth from a small regional provider to the #4 position in the U.S. wireless industry.

“Casey's previous experience with fundraising, public reporting, transaction support and development of finance practices will be an integral part of Nuun's evolving and expanding business,” said Dave Mutzel, CEO of Nuun.

Prior to T-Mobile, Otley spent six years with an international public accounting firm. Otley and his family will continue to be an active part of the Seattle community, while managing the commercial growth of Nuun.

Nuun was recently named as one of Inc. Magazine's America's fastest growing private companies.
