## About

Thornton founded Fiduciary Management Group in 2005 after stints at Morgan Stanley and Credit Suisse, where he sat on both firms' internal recognition councils. An MBA graduate of NYU Stern, he structured FMG as an independent advisory targeting the financial and business needs of wealthy individuals, families, and institutions across North America, Europe, Asia, Africa, Oceania, and South America. The firm manages capital across public equities and hedge funds, according to Altss research, and targets technology subsectors including AI/ML, consumer tech, enterprise software, and semiconductors. FMG's team has included managing partner Ed Butowsky, and a principal at Lifeworks Advisors served as president from April 2018 to June 2022, per a Form ADV filing. Alumnus Allan Boomer went on to found SEC-registered Momentum Advisors in New York. Operational headcount and total deployment figures remain undisclosed. As a multi-family office relying on a service-line structure rather than a pure investment-partnership model, FMG differs from most peer firms.
