If Jerry is still available, by all means get in touch with him. I spent two days with him for lessons 20 years ago when I lived up there. If not, and you don't mind driving a couple of hours to LaCrosse, try Lenny Jaszewski (sp?) at Exclusively Billiards. I took my very first lesson from Lenny and I think he was mentored by Jerry. Lenny does have a website at www.exclusivelybilliards.com
Jerry is a great teacher that really relates well to players. He is still teaching in the area but is usually in AZ during the winters. I haven't talked to him in a little while but I heard he stayed in WI this winter. He is now giving his lessons at the Brass Ring.
Check out his website to contact him. Extremely nice guy that truly loves to teach.
