Reid Shigemura is based in a Music shop in Honolulu, Oahu. He learn luthiery from his father, a Violin maker, (who also apparently made some Ukuleles), and use to work in another musical instrument shop before starting his own in 2011. 

As a result of a successful kickstart campaign in 2015, he started production of a box like travel Ukulele with a detachable neck and internal tuners he calls Pahulele. These come as Soprano or Tenor with a few wood options though mainly birch ply a number of decoration options and an optional pickup.  I'm unsure how large the operation is? at one point he says he is on his own but I have seen pictures of a workshop setting with a number of people working.

These seem to be his main output now but he still includes Soprano standard figure 8 Ukuleles on his site and certainly in the past has made Soprano and Tenor scale Ukuleles plus Guitars under the Ho'okani brand.
