Westfield was established and registered with the Securities and Exchange Commission in 1989 to provide investment management services to institutional and high net-worth investors.
Since inception, assets under management have grown from $130 million to $12 billion. Today, Westfield has 62 employees and operates one office located at One Financial Center in Boston, Massachusetts.
On December 14, 2009, Westfield Capital Management Company, L.P. completed the purchase of the firm from Boston Private Financial Holdings, Inc. (NASDAQ: BPFH). As a result of the transaction, Westfield has been returned to 100% employee ownership which will help to ensure both the long-term stability of its senior management team and key investment personnel, as well as Westfield's continued growth and success. Westfield's partners, led by Will Muggia, now own the firm in its entirety, and continue to have day-to-day operational and strategic control of Westfield.
