Scott Bradford is an expert in casting, rapid-prototyping and CAD design, as well as general bench, fabrication and repair practices. In his time working with rapid prototyping machines, he's been able to complete extensive research in successfully casting with 3D-printed resins. Since joining Rio's Jewelry Tech Team, he's enjoyed being able to work with such a diverse community of jewelers. Gregg Burgard has received multiple awards for his jewelry designs and holds four patents. After earning degrees in Mechanical Engineering and Art, he eventually worked his way up to Director of Product Development for a high-volume manufacturer for Avon, QVC, JCPenny, Walmart, HSN and more. Gregg enjoys using his vast expertise in wax carving, model/mold making, 3D printing, casting and product development to offer options jewelers hadn't considered in the past.

Darla spent the first two years of her career in jewelry sales, earning her Applied Jewelry Professional™ diploma, but was quickly drawn into the world of jewelry creation. After completing the Graduate Jeweler program, she worked in a trade shop for two years before being recruited by a custom design jewelry studio. She spent the next seven years absorbing everything there is to know about being a custom jeweler, learning all phases of repair, casting, fabrication, setting, and especially CAD/CAM. Manuel’s passion for creating jewelry started in his youth, when he apprenticed at a manufacturing company that produced hand-crafted tennis bracelets. At the age of 16, he started working for a firm that specialized in CNC-machined wedding bands. He then worked in retail shops as a bench jeweler and retail sales.
