To chime in,
I was interested in Dr Stubblefields work in Rehab Medicine while he was at Memorial Sloan Kettering in NYC, but he has since moved to Kessler Institute in NJ, so I never went to see him, although it’s only a short distance, but I don’t drive anymore. There are You-Tube videos to watch, plus has a few books $$
I did see last year, a speaking engagement he had with the Explorers Club, which he belongs, I believe about visiting the North Pole, which I would have liked to have attended but the date had just passed.
FYI
