Ran by Mike Bender with his wife Jen. Very nice and very qualified people. My GF and I took their handgun one course a couple months back. I've been itching to get back but have been very busy traveling for work. The have courses all over WIbut the brunt of them are in Lodi. He does both Handgun and Carbine courses.
