Our Story

In 2008, Greg Farrington and Boris Onefater transformed an industry with Constellation Advisers, setting a new gold standard in institutional back-office services. Over 12 remarkable years, the firm expanded its footprint to over 500 global clients and cultivated a team of 120 professionals spread across six U.S. locations.

After selling Constellation Advisers to a strategic acquirer in December 2020 and until their exit in May 2022, Greg and Boris helped run a combined business with over 1,700 global clients and approximately 500 professionals.

With the launch of Stable Rock, Greg and Boris now extend their unparalleled expertise to work with small to medium-sized commercial businesses outside of the investment management sector, that they previously serviced.
