Looks like his contact info is on the link provided. *If* you run into a disconnected # or anything like that, I’ve seen Jack Bart giving lessons at PG Skeet & Trap - if you call there (301-577-7178) either Morgan or Chen should be able to tell you how to get in contact with him. (Back in early 2000’s Jack fitted my wife’s primary shotgun to her and her skeet scores went from 13-14 to low 20’s IMMEDIATELY!)
