Preparing for America's 250th

The nation’s 250th anniversary in 2026 is a rare opportunity to inspire the American Spirit and recognize the individual and collective contributions of Americans. As with any national commemoration, the 250th presents a rare opportunity for thought leaders and organizations to realize audience expansion, institutional advancement, and legacy impact for the common good! We would be pleased to lend our expertise, enthusiasm, and connections to support your aspirations for America’s 250th. The moment is now, time is short, and the path forward is promising!


Consider: What prospects does the nation’s semi-quincentennial hold for your organization and its constituencies? What existing programs or offerings would you like to launch, advance or refresh in concert with this commemorative season?


We are interested to share with you our experiences working with Federal, State, and NGO partners in Semiquincentennial Planning from 2018 to the present. Here are some ways we may help:



  1. Pro Bono Awareness
  • We are interested to share what we’ve learned with those interested to participate in the 250th
  • If there are others you believe would benefit from dialogue, feel free to connect us!


  1. Preliminary Program Analysis
  • Short-term consultation leveraging our team’s experience with Semiquincentennial planning
  • Assess Alignment of Mission/Vision/Values with broadly held “Semiquincentennial Aspirations”
  • Advance program offering, messaging, and alignment with potential known partners and funding channels


  1. More Robust Collaboration as Content Providers and Planners
  • Creative concept design and positioning
  • Content development for the Cultural realm
  • Connections through partnerships
  • Coordination and program management
  • Collaboration on fundraising, strategies, and outlook




We are an unaffiliated federation of subject matter experts and planners engaging in 250th planning since 2018. We believe our collective experience and connections in this regard are helpful to a range of culture-centered partners.
