Chicago, Illinois
Chicago's judo scene is mid-sized but deep, with strong USJA and USA Judo presence and several Eastern European-lineage clubs adding flavor to the traditional Kodokan core. The market spans the city, the suburbs, and university programs at Northwestern and University of Chicago. Winter is the operational reality — six months of cold weather drive a strong indoor training culture.
The local picture
Why it works for Chicago
OLM's AI Monitor separates weather-driven attendance dips (multi-member, time-bound) from individual at-risk patterns. USJF and USA Judo paperwork lives in waiver and member-note fields with auto-renewal expiry, so federation memberships don't lapse without warning. Family memberships use the guardian / dependent model — one billing relationship covering 3-4 family members with separate kyu ranks and journals.
In every Judo gym, anywhere
Kyu and Dan tracking with promoter lineage
Every grading recorded with the issuing sensei, date, and context. If a student moves to another dojo that also runs OLM, their Dan rank lineage travels with them.
Attendance against grading minimums
Set mat-hour requirements per rank. OLM tells you who meets the threshold for their next grading and who's short.
Shiai & event registration
Stripe-powered sign-ups for tournaments and events. Members pay from the app, you get a clean registration list with waiver status.
Multi-discipline aware
A judoka who also trains BJJ keeps separate ranks per art. Cross-training students are first-class in the system.
