Most practicing permaculturists I've bumped into tend to eschew the woo, as it were, but you may want to validate that before signing up to any particular course. (These branches of study can attract certain types of people.)
I did a PDC here in Sydney AU about 15 years ago, and like GP I found it a hugely interesting and engaging process. (The one I went to was run by a lass who had studied under Bill Mollison, which was kind of funky, but as a rule the material covered is much more practical, rational, etc - than deferential / by association to the two guys that kicked it off.)
I took Permaculture New York PDC class (https://www.permaculturenewyork.com/). It was all online but many are in person.
If you reach out to me via LinkedIn (found if you go to link in my profile) we can exchange contact info. I'd prefer not to place it here.
