Private Bank of California announced Monday that David Misch has become its chief executive.

The appointment of Misch, who has more than 25 years of banking experience, is effective immediately. The Century City bank targets businesses, high-net-worth and high-income individuals.

Misch had served as chairman and chief executive of Mellon 1st Business Bank in Los Angeles from 2006 until 2008, when it was acquired by BNY Mellon. After that, he oversaw BNY Mellon’s boutique private bank in Florida.

“I am delighted to be joining the Private Bank of California since it has a strong service-oriented attitude,” Misch said.

Also on Monday, Private Bank appointed Todd Neilson, a founding director, as non-executive chairman. That appointment is effective Jan. 15. Neilson, a CPA, has served as chairman of the bank’s audit committee since the bank opened in 2005.

Misch and Neilson replace former chairman and acting CEO Steven D. Broidy, who is retiring on Jan. 15.

Private Bank shares were unchanged at $7.70 in midday trading on the Over-the-Counter Bulletin Board.
