It’s hard to believe 2016 was 10 years ago! 🕰️

So much has changed in the last decade and yet, so much has stayed the same. Ten years ago, we were celebrating a major milestone: 75 years of serving Peterborough & County. We were raising funds through fun community events, supporting ongoing initiatives like Backpacks for Success, hitting big team milestones, and making headlines alongside media partners who continue to uplift our work.

Now, as we celebrate 85 years, the most important thing remains the same, we’re still here building community and changing lives for people across the City of Peterborough. 💙

Did you know❓
The third Monday in January is widely known as Blue Monday, the saddest day of the year.

The holiday season has passed us by, daylight is fleeting, nights are cold, and the weather is chilly. It’s no wonder some of us are feeling low, but it’s important to know you are not alone 🤍

United Way Peterborough & District is proud to partner with 211 to offer support when times get tough
