Who did Bill Dorrance influence most directly?

Bill Dorrance's most direct influences were felt primarily within the community of working ranch horsemen and vaquero tradition practitioners who sought him out over the decades of his active horsemanship, rather than through the broader clinic audience that Tom's influence reached through Ray Hunt. Leslie Desmond worked most closely with Bill in the documentation of his ideas that resulted in True Horsemanship Through Feel, and her collaboration with him represents the most sustained effort to capture his teaching in transmittable form. Bryan Neubert, a California horseman who worked in the vaquero tradition and who sought out both Dorrance brothers, carried significant influence from Bill into his own teaching and horsemanship work. Martin Black, whose stockmanship and working ranch horsemanship represents one of the most complete contemporary expressions of the vaquero-influenced natural horsemanship tradition, acknowledges Bill Dorrance's influence alongside that of other practitioners in this lineage. Buck Brannaman, though more directly in Tom Dorrance's lineage through Ray Hunt, also acknowledges Bill's influence and the importance of True Horsemanship Through Feel as a reference in the broader Dorrance tradition. The specific horsemen most influenced by Bill tended to be those working in the vaquero context — interested in the complete progression from snaffle through bridle horse and in the ranch horsemanship applications of the tradition — rather than the broader natural horsemanship clinic audience that was more directly shaped by Tom's influence through Hunt and Brannaman.
