Our History
Founded by Mark Sanor, who brings 30 years of experience in single family offices, law, banking, and building 361Firm, we aim to amplify the "magic" of family offices as global change makers while reducing dysfunction. Our community gathers to share insights and learn collaboratively.

Why 361Firm?
Our name, 360 One Firm, reflects our roots and vision:
- 360: Inspired by alumni roundtables started by Mark Sanor in 2005, 360 represents our inclusive, multi-perspective approach to vetting and supporting investments.
- One Firm: Drawing from Arthur Andersen’s global collaborative culture, where Mark was a Partner, we foster cross-border collaboration to understand holistic investment landscapes.
