Pete Ryder, President

Pete Ryder (New Hampshire) got the walling bug in 2015 at a workshop at The Stone Trust. After 32 years in aerospace engineering, working with stone was a big change and tremendously gratifying. Dry Stone Walling has been a growing obsession ever since. In 2016 he founded Touched By Stone LLC to build dry stone walls and features in southern New Hampshire. Pete is a DSWA Level 2 certified waller, and serves on The Stone Trust Board of Directors.

Kim Coggin, Vice President

Kim has been building dry stone walls and structures since 2008. Kim’s journey in stone started shortly after relocating to Pennsylvania from the Southeast, when she became enamored with the numerous covered bridges, stone walls, furnaces, and other historical artifacts in Pennsylvania.

Kim currently holds a Level Two Certificate from the DSWA, and is also a Certified Instructor.  Kim is also an avid faux artist and muralist.  This training gives Kim a unique and profound perspective on the artistic aspects inherent in dry stone creations.

Judy Rand, Secretary

Judy Rand came to a workshop at The Stone Trust in 2014 looking to learn how to fix a wall on her property. Judy found a love for building stone walls and attended many workshops and became Level 1 Certified at The Stone Trust.

TJ Mora

After years of marginally fulfilling work in the world of sports retail, TJ allowed himself to follow his heart…and it led him to stone. He found that it gives him something beautiful and enduring to show for a hard day’s work.

TJ has done several workshops and his DSWA testing through the Stone Trust and decided to give back by taking a spot on the board. He has earned his Level II DSWA certification, and is a DSWA Certified Instructor and has plans to make time in the future to achieve his Level III.
