During his leadership tenure, Citadel increased assets from $411 million at the end of 2001 to its current assets of $5.7 billion, while loans grew from $373 million to $4.9 billion and membership expanded from 76,452 to nearly 255,000, according to the credit union's NCUA Call Reports.

"This decision is never an easy one to make, but I know that Citadel is at its strongest, and I'm so proud of all we've accomplished and the many talented people I've had the honor of working with," March said in a prepared statement. "In 22 years as CEO, every expectation I've had for this company has been exceeded – whether it be financial, technology, growth of our team, or investing back in our members and community. I have every confidence Citadel is on a path to even greater growth and success."

Citadel's 539 employees operate 25 locations.

The search for March's successor is underway with the goal of naming a new CEO in the coming months following a transition period, the credit union said.

Britton joined Hughes in 2003 and most recently served as the credit union's EVP of lending before he was named CEO.

"Our board and employees look forward to continued growth and stability while helping our members improve their financial lives under his leadership."

Britton's management style focuses on empowering employees to be successful and recognizing their professionalism and commitment to the financial well-being of Hughes members.

"I believe in taking care of our staff so they, in turn, will take excellent care of those we serve," he said.

The credit union's 277 employees operate seven locations throughout Tucson and serve more than 178,000 members.
