Financial industry veteran Bob Mulholland is retiring as the head of UBS Wealth Management Americas Client Advisory Group, UBS Wealth Management Americas’ President Bob McCann announced in an internal memo released Tuesday.

Mulholland had overseen the firm's 7,000 financial advisors in the U.S. and Canada. Brian Hull, who had been UBS’s head of strategic clients and partnerships for the U.S. wealth unit, is succeeding him.

Mulholland stepped down after 36 years on Wall Street to spend more time with his family as he expects his first grandchild, according to the memo. McCann said Mulholland served as one of WMA’s key members of its renewal team. 

Hull served as head of WMA’s Strategic Clients and Partnerships, and as a member of both the WMA and Americas executive committees.

In other advancements, John Matthews will join the WMA executive committee. He will take on the expanded responsibility for the Americas Global Family Office and Business Development Group while continuing to run Private Wealth Management.
