Skype Video Lessons 
It's also possible to have long-distance lessons via Skype. Obviously a face-to-face lesson is better, but this can be a good supplement (or simply a means to avoid airports!) Contact Park for rates and scheduling.
Workshops & Masterclasses:
If you are a teacher (or very motivated student!) and would like to organize a workshop in your area, please contact Park directly. Workshops can cover anything from a one-time introduction to jazz/blues to a permanent ongoing class. Class size is entirely variable, from 3-4 to thousands (although this gets a little complicated, logistically)
