100 listings · 3,921 ranked · 3,921 tracked in California
Ordered by MSP Score, highest first. Where two providers hold the same score the older record is listed first, so the order is stable between runs. A provider with no score is not ranked and does not appear.
No movement column. The scoring formula changed on 2026-09-17, so ranks either side of that date are not comparable and the last 30 days start on 2026-08-23. Movement returns once a full window sits after the change.
