Light The Houses Radiothon

Tune in to help keep families together.

Our 2023 Light the Houses Radiothon is a wrap! Thanks to your generosity, this year’s event raised an impressive $253,987 for families staying at Ronald McDonald House Denver. This beloved event on KOSI 101.1 has become one of our largest fundraisers. Stay tuned for details on the 2024 Radiothon — we hope you’ll consider aligning your company with us by becoming a sponsor and showcasing your commitment to community giving next holiday season.

Each year, we partner with KOSI 101.1 for our Light The Houses Radiothon fundraiser. Tune in on December 5th this year to learn how you can be a Ray of Hope for our families.
