I read an article on the retirement of Jennifer Gelfand (see link under Boston Ballet thread), and found it interesting that she gave David Howard much of the credit for her training.
I know David Howard also contributed to the training of Gelsey Kirkland, and worked with Katherine Healy (dancer and also profiled in "A Young Skater") from a young age.
It seems that this training was provided in addition to, and outside of, the training received at the student's school or company.
Has this kind of training gone out of vogue? If so, is it because no great coaches are around to provide it? Or...??
