We should be thankful that a few good British builders decided to come ashore in the USA! Along with Dave Moulton, Colin Laing also comes to mind.
A few Americans did cross the pond to learn how to do things properly before coming back to the US to wield a torch, including Matt Assenmacher of Michigan.
We are fortunate to have in Tucson, AZ a couple great custom frame builders: Andy Gilmour of Gilmour Bicycles and David Bohm who builds under the Bohemian name.
Andy will build to the latest specs/trends/materials, while Bohm is more the classic style builder, including very ornate handmade lugs.
Nice to still have a choice!
