While working for Salmon Bay Glass in 1993 owned by Frank Englesby, Dehanna met fellow glass artist Jacqueline Mendelson and soon after they began working together. After a series of successful collaborative designs and the need of their own private studio they decided to build their own hot shop and open Totally Blown Glassworks, located in Georgetown, WA, in the summer of 1997.

Being a partner in a glass hot shop has allowed her the resources to undertake much larger projects while still making her individual original creations. In 2002 she was able to work with the Tacoma Glass Museum by blowing the 750 floating glass apples needed for the outdoor installation designed by Berkley, CA artist Mildred Howard titled ‘Blackbird in a Red Sky (aka Fall of the Blood House). In 2003, she was to cast blue colored glass 12’x12’x1’ textured tiles to construct a 4 story glass staircase for a private home in Seattle, WA.
