UBS in the US has hired Lee Bailey Konopka and Stephen Ruvituso as senior vice presidents in investments, based in UBS' Private Wealth Management office in Stamford, Connecticut, where they will report to executive director Mary Barneby.

Both join UBS from the Stamford office of Citigroup's Smith Barney, where they worked with clients in the ultra-high-net worth segment as well as family offices. Also joining are Julie Ackerman and Todd Stankiewicz.

Mr Konopka specialises in equity trading and institutional sales and Mr Ruvituso in managed money, municipal securities and family foundations.

The Stamford Private Wealth Management office was opened in July 2007 and is dedicated to servicing UBS' ultra high net worth clients. It is part of a series of planned offices across the US that will offer a comprehensive suite of brokerage, trust and private banking services.
