Mike Da Silva started Da Silva Ukuleles in Berkeley, California in 2005. In that time he's become one of the most respected luthiers around and has built up a very impressive client list that includes John King, James Hill, Pops Bayless and even Warren Buffett. You can take a look at his ukes here but the highlight has to be his painstaking reproductions of the Santo ukuleles.
As well as luthiering, he also hosts workshops, gigs and get togethers which you can find on his website.
