Kala was founded in 2005 by Mike Upton and they are one of the brands with a head office in California but most of the Ukuleles are made in China. When Mike Upton first started his own company he used the brand name Lahaina but decided that this was too close to Lankani, (his previous employer), so it was changed to Kala They no longer use Lahaina to brand Ukuleles but it is still the official company name.
This has nothing to do with the Japanese brand launched by Hosco in 2011 called Lahaina

The Chinese range is very large and covers all scales of Ukulele, including Minis, (they call Sopranino's), Long Necks and Bass Ukes, plus Resonators, Double G's, Lili'us and Taropatches with a lot of different solid and laminate wood finishes; and even Banjoleles. Kala have also added acoustic Guitars to their range and a Tenor Guitar is included amongst them. 

Other branding used by Kala includes a budget range called Makala and this range spans all sizes except Mini and includes the part plastic Dolphin and, (starting 2013 to counter all of the fake Dolphins that have been made), the Shark. In 2015 they added a range of fully plastic Ukuleles calling them Makala Waterman. They also have a very colourful range that started out being called Ukudelic by Kala and priced above the Makala range when it was launched in 2011, but for 2014 they added extra designs and reclassified this range as Makala Ukudelic. 

Kala are also the brand that started mass producing the Bass Uke, (invented by Road Toad with whom they work in conjunction), as U-Bass and have gone on to bring out a range of Solid Body Bass Ukuleles that they call S.U.B. (Solid U-Bass) in 2013 they added a cheaper U-Bass that used the thinner steel wound strings developed by Pyramid for Stevens Guitars and called this the U-Bass Rumbler.

In the mid 2010's they started selling U.S. made premium Ukuleles and Banjoleles to the brand some of which are made in a workshop/factory in California and some of which were supplied as piece work by U.S. luthiers
