Ron Sweeney will become president/CEO of Sierra Central Credit Union in Yuba City, Calif. in January.
He will succeed John Cassidy, who announced his retirement on Monday. While working as a manager for Great Western Bank/Washington Mutual Bank, Cassidy was named CEO in 2000. Under his executive leadership, the credit union's assets grew from $253 million in 2000 to $1.4 billion, by the end of this year's third quarter, according to Sierra Central's Call Reports. In those same years, membership expanded from 63,000 to more than 73,000. The credit union's 228 employees operate a corporate office and 19 branches.
"After 22 years as our CEO, he (Cassidy) is moving on to the next chapter in his life and will continue to work on charitable causes throughout the state, as well as regional economic development efforts that improve the quality of life for individuals, families and businesses throughout Northern California," Sierra Central said in a prepared statement.

Sweeney, who worked as a principal examiner for the NCUA in the early 1990s, joined the credit union in 1999 as a consultant from the $4.6 billion Travis Credit Union in Vacaville, Calif., where he served as vice president of IT. At Sierra Central, he was promoted to CFO and COO. In 2013, he was named Sierra Central's president.
Melanie Vest has been named the first female president of the $1.4 million DATCU, the Corinth, Texas-based credit union announced.
Glen McKenzie will continue serving as CEO.
Vest began her credit union career as a part-time teller at DATCU while she was attending college in 2002. Since then, she has worked in several leadership roles and most recently served as EVP and CFO, the credit union said.
DATCU's 209 employees operate a corporate office and 12 branches that serve nearly 100,000 members.
