Damon Tso is a Navajo potter. I haven't seen anything new of his in a while but I know he's still working: he earned a nice ribbon at the 2019 Santa Fe Indian Market. He's also on the schedule to do a pottery making demonstration at the Grand Canyon in February 2020. But I haven't found much else.
Damon uses the same Black Mesa clay as the Williams family. He sometimes likes to add a much larger biyo' than they use and he sometimes carves designs that flow around his pieces. Like the Manygoats family he also sometimes adds larger designs in repousse.
From the above I would guess that he's from relatively close to Black Mesa. Most of the Navajo potters in that area benefit from the nearby Shonto Trading Post and its owner: I've heard he's constantly encouraging and supporting them to do more and better. He also provides them with a well-known nearby marketplace.
