Heard of Torishimaru Aiki Jutsu?

I am currently reading a book "Teachings of a Grand Master" by Richard Behrens, Grandmaster of Torishimaru Aiki Jutsu. I have searched for more information on Richard Behrens, and Torishimaru Aiki Jutsu on the internet, and can't seem to find very much at all. This is extremely surprising for a guy who is considered to be one of the foremost martial arts masters in the world, maybe that's self professed. Is he for real, does anybody have any info on him or his style?
