Tracking down the authors of “Bach for Banjo” (Hal Leonard Pub.)

I’m really enjoying this booklet, I spent $10 or something for 20 Bach pieces included, all well arranged, and have spent many many hours learning them. I would like to reach out to the authors for specific questions but not sure if they are actually banjoists. Does anyone know if they are on the hangout?
