Brown Advisory, an independent investment management firm with $33 billion in client assets, has taken on Malcolm MacColl to help build up its presence in the New England.

MacColl joins as a partner in the firm’s Boston office. In his new role, he will be tasked with building out the investment and client service arm for private, institutional and nonprofit clients in the U.S.

Previously, MacColl worked at Crosswind Investments, an investment management firm that he founded and worked for until it was sold to Lee Munder Capital Group in 2012. He had also spent 18 years prior at CS First Boston, which is now Credit Suisse.

“Malcolm’s insights will be very helpful to Dune Thorne and her team in Boston as they expand our business serving private clients and family offices,” Michael D. Hankin, Brown’s president and chief executive, said in a statement. “We are fortunate to be able to reinvest in our business and attract talented individuals like Malcolm, who will also uncover opportunities for us to serve institutions and nonprofits, whether in a single investment strategy or in an outsourced CIO capacity.”

Brown Advisory is a world-wide investment management firm with clients in 49 states and 18 countries and has over 300 employees who are all equity owners of the firm.
