The Chief of Staff network has been incredibly helpful for me, and I honestly started seeing immediate value on Day 1 of joining.
The network offers numerous opportunities to further growth, development, and camaraderie - I think it'd be challenging to navigate the CoS role alone without this group of people.

Chief of Staff Connect 2024
We’re bringing together 120+ select senior chiefs of staff from across industries and geographies for two days full of discussion, problem-solving, and fun.
With this year’s theme – “Company Blueprints & Chief of Staff Toolkits” – our aim is to give you actionable takeaways on strategy and tactics, not just rose-colored-glasses stories and impractical theories.
