Family offices are private wealth management advisory firms that serve ultra-high-net-worth (UHNW) investors. They are different from traditional wealth management shops in that they offer a total outsourced solution to managing the financial and investment side of an affluent individual or family. There are a wide range of family office models are in use today. Just as there are a number of key differences between single family offices, and multi-family offices that serve several unrelated families. But whatever the key differences may be, the common denominator is that the office serves only one family, which may include multiple generations or even family branches.
