Sara Adams

Sara has been making and selling her creations since age fourteen. After a career in nursing, and raising four children, she returned to her love of art. In 1980, she studied and taught painting and other crafts, opening an art studio in St. Augustine, FL in 1990. Eventually, her love of jewelry led  her to wire art. First, she studied privately under  Cherie Crist, and then she found William Holland. Sara has studied under Jessie Donnan, Betty Baxter, Ruth Ann More and Gene Sheridan, and has experienced wire sculpture under Irene Francis and Dianne Mason. She has been teaching at William Holland since 2003 and is dedicated to the School.



imageSteve Adams

Steve is a retired Air Force officer and former systems analyst. He began cabbing in 2005. He is also a rookie opal cutter. Steve learned cabbing so his wife Gloria could use his cabochons in her wire wrap jewelry. As he learned, his passion developed and he discovered it was both relaxing and fun. Steve is a member of the Alabama Mineral and Lapidary Society and is a juried member of the Alabama Designer Craftsmen.

His cabochons can be seen online at:

imageLance Andrus

Lance graduated from SUNY Potsdam with a degree in Geology and a Masters in Secondary Earth Science. He currently teaches eighth grade science in Fayetteville, NC. He and his wife Laura discovered the peace, tranquility and sense of family that William Holland offers in 2007. They have been members of the family ever since. Lance began faceting using Jeff Graham's instructional book and refined his craft by taking classes from David Corn at William Holland.


imageDavid Bergquist

Dave has always had an interest in minerals and fossils. After retirement, he joined the Rock Club in Fort Walton Beach, FL where he began to develop a variety of lapidary skills. He started taking classes at William Holland and Wild Acres in 2007. Although many lapidary skills were  enjoyable, cabochons quickly became his favorite. Soon he had a basement full of grinders, laps and polishers, and too many rocks to store neatly. He and his wife, Sandra, started a small lapidary and jewelry business selling out of their home, on the Internet and at art and craft shows. Wanting  to foster enthusiasm for his craft in others, he eventually started teaching lapidary at home and in his club. David treats each cab as an object of art, attempting to develop and present the unique patterns and colors of each stone to obtain the most interesting and pleasing result. Because his enthusiasm for lapidary is infections, David's classes are always entertaining and rewarding for beginners and old hands alike.


imageSandra Bergquit

Sandra's interest in lapidary and wire art began with a two­ hour class in wire wrapping in 2004. Fortunately,  her husband David, a long time rockhound, was pleased to encourage and support her new passion by providing customized cabochons. Unfortunately, limited opportunities for  learning   wire  wrapping   in  her   home  area  left    herfrustrated when she wanted to go beyond that initial course. Then, she was directed to William Holland. To repay what she has calls "The Gift of William Holland", she vowed that, if she ever became good enough, she would teach every chance she got. Consequently, Sandra (who started teaching in 2008) has taught for a number of organizations in a wide variety of settings. In addition to  teaching  Wire and Chain at William Holland, and to the members of her home rock and gem club, she is currently providing private lessons while also teaching workshops in her home area. Because her workshops include students of widely varying skill levels and interests, Sandra has become adept at managing multiple, concurrent projects for diverse groups.


imageBill Boggs

Bill began attending William Holland in 1993, and started teaching classes in 1997. He is experienced in lapidary, wirecraft jewelry and metalsmithing, but his first love has always been finding, cutting and polishing rocks for display or jewelry. For Bill, intarsia is a unique way to show off nature's rock and mineral creations, combining them into endless combinations of colors and patterns limited only by the imagination.


imageSteve Bostwick

Steve is a practicing Forensic Architect from Wyoming, OH who spends as much time as possible in his family jewelry studio, Cabochon Works, LLC. He began his history with rocks collecting pocketfuls of stone and arrowheads. After a pretty rock informed him that there should be more to rockhounding than just collecting, Steve taught himself to cab. An advertisement for William Holland in a rock magazine prompted him and his wife to take multiple  classes over the past seven or eight years, routinely  bringing along a couple of their four children. Steve's  classes at William Holland have included Cabochons, Opals, Silver, Faceting, Chain and multiple Casting classes. Steve is a faceting instructor, primary  cabbing  instructor and program director for the Cincinnati Lapidary and Faceting Society. At Cabochon Works, Steve provides faceting and cabbing lessons, rebuilds and sells used lapidary equipment and produces custom metalwork and jewelry for sale, as well as providing stone cutting and polishing services to private clients and well-known custom and art jewelers.

imageNancy Brickner

Nancy learned an appreciation for many forms of art from her parents. They both opened doors to art during her childhood that have remained opened throughout her adult years. Chaining, she learned from her father. He shared his joy of teaching with Nancy as he taught her which tools to use and how to use them, as well as how to read and adapt patterns to achieve even more difficult and original designs. Nancy has taken several classes in chaining, wire wrapping and smithing at William Holland and the Society of Midwest Metalsmiths' Masters of Metal. As a juried member of Best of Missouri Hands, she has displayed her art across the state, including many years as a demonstrating artist at Silver Dollar City's Fall Festival. Teaching was the next step in Nancy's jewelry career. Sharing her skills and seeing people learn and create beautiful pieces of art brings her much joy. She has taught for many years at different workshops, craft camps and venues such as the Bead and Button Show in Milwaukee, WI.


imageDiane Brooks

Retiring after thirty years in corporate information systems, Dianne needed an outlet for her artistic energy and, in 1999, discovered she loved making silver jewelry because it requires the skills of a technician and the eye of an artist. She also creates intarsia and fused dichroic glass to incorporate into her designs. Usually a stone will tell her what it wants to be and then guide the design. Dianne now works in various metals using fabrication, enamel, precious metal clay and wire techniques. She has been teaching Silver I and II, Cold Connections, Enameling, Polymer Clay, and Glass Fusing at the Visual Arts Center in Punta Gorda, FL since 2001. She has taught Cabochons at William Holland since 2006 and Enameling since 2011. Diane is a member of Florida Society of Goldsmiths and co-founder of the Jewelry Arts Group at the Visual Arts Center.

imageSandy Cline

Sandy is a self-taught sculptor who has been developing  his skills for over fifty years. He credits his successes to the insight gained from studying Malvina Hoffman's books on sculpture. He has taught carving in colleges, museums and schools across Canada and the United States. Sandy refuses to believe that carving requires any special talent. Rather, he prefers to trust that the urge to create is inherent in all of us, and that the teacher should promote  these values in those seeking that knowledge. His classes create a very congenial, cohesive atmosphere that has resulted in some excellent carvings from students who never believed they could carve. Sandy has been asked to create pieces for awards and presentations by various colleges and organizations such as Sir Sanford Fleming College, the Canadian Synchronized Swimming Team, the Cleveland Museum of Natural History, the Canadian Nurses Association, Sports Canada and the  Women's  World Hockey Championships. Examples of his work can be  found  at:  http://www.soapstonesculpture.com
