Gallery Boom started life as the first all local art gallery in Tumwater, WA. It started in 2014 as part of the Tumwater Chamber of Commerce Business Incubator Program. It was located in the former Tumwater Chamber of Commerce Building in the Fred Meyer parking lot for two years. The BOOM in Gallery Boom came from the Island of Harmony Boom, an art project from former owner and artist P. Calavara and Christine Malek. The gallery started as a way to promote the books, stuffed creatures and other products of Hamony Boom. It developed into a dynamic and innovative way to promote and support local artists. The Tumwater gallery hosted art classes, events and a Sunday Art Market every Sunday during the summer.
