Interesting, the juniors are much more varied. The last 5 have all been from Texas, but so far about half of all junior winners train somewhere other than Texas.
Just as interesting, imo, is the fact that winning juniors in the last 15 years doesn't mean anything as far as senior success. Of the 10 junior winners from 2010 to 2023 (O'Keefe won twice), 8 of them never made a world or olympic team--and DiCello only barely counts since she was sent to the weird 2021 worlds and was an alternate for 2021 olympics and 2023 worlds. Heck, if not for the record number of injuries at Trials last year, Rivera wouldn't have made Paris. Of late, junior success is not assurance of senior success--which was not the case from 2000-2009.
