Info on KunTao & Arthur Sikes

Has anyone here attended a seminar or class with GM Arthur Sikes, Master Carl Spitali, Master Joe Salamone?

If so can you provide any information on Kun Tao, upcomming seminars, resources ect.

A friend told me about GM Sikes a few years ago and I cannot find any info on him, his students, or his teacher Williem Reeders (Liu Seong) except for a book I have by Master Joe Salamone, on Indonesian Tai Chi.
