A few people have asked. We have no gunsmiths just some armorers.

Tom is certified by Glock and S&W for the M&P.
Andy is Glock certified.
Aaron is Glock, SIG, Remington, M&P, has build a 1911 in a Larry Vickers course, Knight's, and the advance M4/M16/AR15 from SAW.
I'm Glock advanced, M&P, and advanced M4/M16/AR15 from SAW (Ken Elmore).
Two of our volunteers are M&P as is another part time employee.

I think I'm missing something though.

For actual gunsmith work we normally recommend Bret Evans at Northwest Armswerkes for bolt action and precision rifles, and Dave Neilsen at Southridge Arms and Refinishing for 1911s and any refinishing.
