Doubt Signal by Capt. Jerry Hasselbach
Captain Jerry Hasselbach, Lead NSAP® Assessor and Instructor at MITAGS, has had the ability over the last several years to witness and assess over 1000 NSAP® sessions. During these sessions, Captain Hasselbach has gained more knowledge and lessons learned than he could have originally imagined, leading to what has developed into a presentation on the Doubt Signal.
