Ryo Nishiumi is very talented, meticulous, and truly knows his craft. I had a damaged 10 panel Asian calligraphy screen. He discussed the techniques and challenges of the restoration. When he completed the work, the craftsmanship was very excellent. With East Asian art, going to a conservationist whose focus is on western art is a mistake that can result in expensive damage to a piece. I was so pleased to find Ryo. This was a family heirloom and he did a great job.
