Dave took up the whaler's art of scrimshaw while aboard ship during the Viet Nam War. He has a degree in wildlife ecology and worked over 25 years in the U.S. Fish and Wildlife Service as a wildlife law enforcement officer and wildlife refuge manager of some of the largest refuges in the United States. While Dave doesn't scrimshaw much these days due to a neck problem, he does incorporate bone and antler into many of his fiber art tools.

After his retirement in 2002, Dave was introduced to tatting shuttles by a customer at an art show he and Jo were doing on the Oregon coast. It wasn't long before he became well known on Ebay for not only his handcrafted tatting shuttles, but also his lace making tools, crochet hooks and spindles. Dave now sells his fiber art tools exclusively on Etsy.com and has satisfied customers all over the world.

Jo has been married to Dave for 38 years. While a musician by training, she enjoys working with earthenware clay, pine needles and ancient ivory. Jo previously sold her ceramic jewelry on Etsy under the name of "Good Dirt Jewelry". Jo also does all of the photography for Grizzly Mountain Arts.

Jo and Dave work together to create all of the fiber art tools and other items sold in their Etsy shop.
