In 2007, they founded Two Tone Studios in the West Seattle neighborhood of Seattle, WA. They chose to establish their studio in the Pacific Northwest to be a part of the rich glass community that exists in the region. Their studio name refers to the use of color as well as the two voices behind the work. Each piece is designed and hand made by Sugiki and Zerkowitz, from sketch to finished piece. They are well known throughout the glass community and have been invited to many prestigious institutions to lecture and demonstrate in this country and abroad.

In addition to the Two Tone Studios line, Sugiki and Zerkowitz also make one-of-a-kind pieces that you can see on their individual websites:
