Sounds to me like when Ross Perot (you can tell my age) was describing how Texas deals with snakes. "In Texas, when you find a snake you kill it, you don't form a committee on snakes". I would react in exactly same way. Anyone can just do a job, Masters are all about the passion, experience and finesse in that order.
There are few Masters in the business across the country IMHO, and I have been privileged to have my car worked on by two of them, and received the advice of several more. Hope that you get an answer, the Masters know one another, and should you need a couple to ask, let me know. I do know that there is one in Brookfield WI, not sure at what level. It appears that there are enough of you up there to get some good first hand opinions I am sure. Just happened to see your post.
Best,
