He's a great instructor, coach and mentor. Clients love his wisdom and openness to share his knowledge. He receives great evaluations on his teaching. Hal was also a mentor for our new instructors. He would work with them one-on-one to get them up to speed, give them pointers about teaching our classes, and co-teach with them until they were ready to solo. He knows his stuff, and has a good heart.”
