UBS Wealth Management Americas has confirmed the departure of Pat Mendenhall, the manager of its Houston, Texas branch.

Mr Mendenhall, who had been with UBS for 19 years, chose to retire from the Swiss bank to pursue other opportunities within the wealth management industry.

Mr Mendenhall was appointed branch manager in 1994 and became a managing director of UBS Wealth Management in 2007. According to reports, he was responsible for $42 million out of the Houston branch's $67 million in revenue.

Last week news emerged that Michael Weisberg, head of products and services within UBS Wealth Management Americas, is to leave the bank.

Mr Weisberg has taken an indefinite leave of absence due to personal rather than performance-related issues, the firm said.

Taking over Mr Weisberg’s responsibilities is James Hausmann, a specialist in fixed-income. Mr Hausmann has headed transaction products in the Swiss bank’s Americas wealth management group since 2005; he joined Paine Webber - the wealth management unit bought by UBS in 2000 - in 2001.
