FORTUNE — Mark Zanoli has stepped down as head of U.S. technology investment banking at UBS, Fortune has learned.
Zanoli originally joined UBS (UBS) in July 2010, following 17 years with J.P. Morgan (JPM) and Hamrecht & Quist.
He was based in San Francisco, and at one point led a team of around 40 professionals. That figure was slashed by more than half late last year in a large round of UBS layoffs, while more cuts occurred earlier this year.
Today, UBS has just a handful of full-time tech investment bankers based in San Francisco, including Janine Sheflo (media/Internet), Sam Powers (telecom), Ben Freeland (software) and John Katzenmeyer (financial tech). The firm also recently added Johnny Williams — the former co-head of tech equity capital markets with BoA Merrill Lynch (BAC) — as vice chairman.
No word yet on Zanoli’s future plans. A UBS spokeswoman declined to comment.
