With all the challenges and political polarization we face, it is easy to forget there are still good things happening in the world. And in NH, that includes many companies, nonprofits and institutions celebrating milestone anniversaries.

We scoured the internet, press releases, magazine surveys for our top business lists and more to find out who else was marking a special anniversary in 2025. (If we missed you, we apologize). We chose one organization from each milestone era to profile, though running alongside them you will find listings and brief descriptions of others also marking a big anniversary.

These organizations have proven their staying power, and each are finding a way to influence their industry, their communities and/or the state. We applaud the many organizations that celebrated big anniversaries in 2025. 

If you are celebrating a milestone anniversary in 2026, contact Executive Editor Matt Mowry at mmowry@granitemediagroup.com to make sure you are included in next year’s milestone anniversary section.
