The Big 550 KTRS Radiothon

Why Your Support Matters

Each summer, our partners at The Big 550 KTRS dedicate a full day of broadcasting to the St. Louis Men's Group Against Cancer. On Thursday, August 20, we take over the air from 6:00 a.m. to 6:00 p.m. Hosts share stories, take calls, and invite listeners to give throughout the day, alongside interviews and auction packages.

Here is what your gift does. STLMGAC raises the money. St. Louis organizations put it to work. Funds are awarded as grants to local organizations working in cancer research, prevention, and patient care, right here in our community.

How to Listen

Tune in on 550 AM, stream at KTRS.com, or download the free KTRS app on Google Play or Apple. Listen from anywhere and give from anywhere.

For questions, contact Anita Kraus at anita@mensgroupagainstcancer.org or 314.786.5950. All donations are greatly appreciated!
