The two statements are not contradictory. UTD did have its origins in the Florida cave diving community, but it does not have a significant presence there now.Interesting. From my (ignorant) perspective, I thought they'd grown out of the caving community!
I know by reputation they're quite strict with their standards of uniformity and they've adopted some odd manifold thing for sidemount.
This is my understanding:
Andrew Georgitsis was active in the WKPP and training director for GUE before being fired by GUE. He then was in charge of NAUI tech before being fired there. He then created UTD, with its base in California.
