Meet Our Instructors
Sharing knowledge is at the core of everything we do, and our instructors are central to that purpose. Each one brings their own experience, creativity, and enthusiasm for making, helping our community explore diverse skills and inspiring, project-driven learning. We celebrate instructors who share practical tool knowledge alongside unique and imaginative class topics that spark curiosity and empower hands-on confidence. By teaching here, they help members and first-time makers alike discover that they are capable of creating something meaningful with their own two hands. We’re proud of the talented teachers who contribute their passion, expertise, and support to keep the maker spirit thriving in Central Oregon.

Will Vaughn
Instructor - Woodworking
Will has been woodworking pretty much his whole life. He recently moved to Bend from Philadelphia, where he taught woodworking classes and worked with students one on one. These days he works as a cabinet maker, and when he's not at work he is usually building furniture or restoring old hand tools.
Will enjoys teaching and helping people get comfortable in the shop, whether it's their first project or their fiftieth.
John Sweet
Instructor - Glass
John is a kiln-formed glass artist whose personal work specializes in creating custom fused glass pieces inspired by kids’ drawings. His classes blend playful experimentation with clear, hands-on instruction in foundational fusing techniques. He loves celebrating the imperfect, imaginative spark that happens when ideas meet molten color.
Dennis Lorenzetti
Instructor - Woodworking
Dennis spent his career inspiring young makers as a high school woodshop teacher. In retirement, he’s carried that same love for teaching and craftsmanship into the woodworking community at DIYcave. With Mo—his loyal shop dog and supervisory sidekick—by his side, Dennis continues building creativity, confidence, and hands-on skills in every class.
Christy Tice
Instructor - Woodworking
Christy grew up repairing and restoring instruments with her dad in his stringed instrument business, which sparked what has turned into a lifelong passion for woodworking, repair, and learning new skills. Several years down the road, fueled by these passions, she started her own business, Handymandy, which offers “major help for minor jobs”. More info about Christy and her business can be found on her website.
Mani Pureheart
Instructor - Lapidary
Mani Pureheart will tell you, with his trademark big grin, that he is probably the youngest octogenarian you’re liable to run across.
He sold his first stone over 75 years ago, and has been cutting gems for over 60 years. A designing and manufacturing jeweler and lapidary for most of his life, he raised a family by selling handmade, high-quality jewelry from one of his three jewelry stores. He is trained at the Gemological Institute of America in both colored stones and diamonds, and for many years has been a rock and gem dealer at Pacific Northwest rock and gem shows. He had a gem laboratory and appraisal service, now closed, and has specialized in rare, unusual, and extraordinary rocks, whether it be turquoise, agate, or a fine gem garnet, tourmaline, emerald or sapphire, or any of the many other gem species.
Mani is widely regarded as an expert in his field and loves to teach. He says, “There is absolutely nothing as beautiful as a smile on the student’s face when they hold up their first polished gem and behold its beauty.”
Jesse Pemberton
Instructor - Welding & Machining
Artist through & through, Jesse discovered an affinity for metalwork while earning his Fine Arts degree at UC Santa Cruz. Known for his abstract work in sculpture and public art collaborations, he also teaches multi-process welding and machining techniques to beginning and advanced students.
Emily Gannon
Instructor - Jewelry
Emily started making jewelry in 2020 when she took the very classes she now teaches at the DIYcave. She fell in love with silversmithing and has been creating custom pieces ever since. Emily is a Central Oregon native and loves the outdoors and spending time with her two pups.
Kaitlyn Rich
Instructor - Sewing and Fiber Arts
Kaitlyn has been sewing for over 30 years—learning from her mom and breaking the sewing machine many times along the way. Sewing most of her own clothing, Kaitlyn has made waxed cotton jackets, many pairs of pants, & her own gear, like climbing chalk buckets from repurposed rice bags. She loves to support fellow makers in sewing whatever they dream up!
Jesica Carleton
Instructor - Mosaic, Fused Glass, Metal & Computer Design
Jesica is a multidisciplinary artist and instructor whose lifelong creative journey began at an early age, with an enduring passion for exploration across countless media. As a full-time artist, her current work includes mosaic, fused glass, metalwork, and computer-aided design, all shaped by her love of experimentation and willingness to embrace both left- and right-brained processes. As a dedicated teacher, she is committed to helping others tap into their own creativity, believing strongly in the accessibility and empowering nature of glass art.

Donna Yutzy
Instructor - Jewelry
When Donna discovered Metal Clay, a moldable metal, she found she really enjoyed the ability to get rich textures and patterns and the freedom of expression from this wonderful medium.
Metal clay is fired in a kiln where the binder is burnt away and when finished you are left with only the silver. In her jewelry she uses fine silver and sterling silver. To add color to her jewelry she uses natural and faceted gemstones in a variety of earth tone colors.
