Is the only allergen concern peanut and tree nut? If so I'd skip the indie bakers obsessed with gluten free as a lifestyle health promotion. Coming from someone who has kids one PA and the other ana to wheat, barley, usually the two are mutually exclusive. The only ones I know of that really get it as in an honest to goodness bakery is Franz and that's because I talked to them leaving no stone unturned and they answered in a clear way signifying they "got" it. Like we do.
