2024 Board Members

CoMA is run by a volunteer board. We are all metalsmiths of varying stripes and believe that connecting artists is the key to building and maintaining our vibrant metal arts community in Colorado. Board members are elected at the Annual All Members meeting for two year terms even if they are appointed when positions become vacant before our Annual Meeting. If you are interested in joining the board or volunteering in another capacity (we can always use help!), contact our President, Kim Harrell, at

For 2023, the board will meet from 12:30 - 2 PM on the third Sunday of the month in February, March, April, May, June, September, October, and November. Traditionally, we hold a board retreat in January, and an annual members' meeting during our conference in July. Please note that dates and times are subject to change at short notice, but we will communicate such changes to our CoMA members.

She studied at the London Metropolitan University, Sir John Cass School of Art, Architecture and Design where she obtained a B.A. in Silversmithing, Jewellery and Allied Crafts. Kim is a Denver native and currently resides in Aurora, CO where she runs a private design studio, and teaches at The Art Students League of Denver. Her work can be found at Forsythe Fine Jewelry in Buena Vista; Mountain Home in Evergreen, and Aurum Jewelry in Denver. Kim's work is in several private collections in the USA and Europe. The Kirkland Museum of Fine & Decorative Art, now under the Denver Art Museum, in Denver, acquired a set of her sculptural spoons for their permanent collection.

Kim has 18 years of board experience and is a graduate of the Colorado Business Committee's Leadership Art training program, and of Leadership Aurora. She was appointed by two successive Governors to serve on the Colorado Creative Industries Commission and has sat on numerous public art selection committees for the city of Aurora and the State of Colorado. Kim was a co-founder of what is now known as the Aurora Cultural Arts District and continues to be an active member in the Denver-metro area arts community as an educator, board member, donor, collector, and art business woman.

"I volunteer with CoMA because I love being part of a group of 'metalheads'! It is such an important aspect of sustaining connection with colleagues, learning new things, sharing our knowledge and giving a hand up to the next generation."

I am multi-skilled with a diverse educational background and a distinguished career in the technology industry, as well as a passionate pursuit of the arts. With a relentless drive for learning and innovation, I have made contributions in both the corporate world and the world of fine craftsmanship.
My educational journey is a testament to my thirst for knowledge and versatility. I hold a degree in Art, reflecting a deep appreciation for the aesthetic aspects of life. This foundation in creativity and aesthetics would later intertwine with my other pursuits. I earned a Bachelor's degree in Business, equipping me with the skills necessary for strategic thinking and entrepreneurship. My academic journey didn't stop there. I also hold a degree in Computer Science, which served as a bridge between the worlds of technology and art. The blend of technical expertise and artistic sensibility became a defining characteristic of my career. I capped off my educational live with a master’s degree in engineering. I dedicated 38 years to a career at IBM, one of the world's leading technology companies. During this extensive tenure, I undertook various roles, showcasing my adaptability and versatility. From software development to project management, my expertise spanned a wide spectrum of responsibilities. My understanding of both technology and business allowed me to contribute significantly to IBM's technology mission.
Outside of the corporate realm, my interests are equally compelling. They are the Vice President of the Colorado Metalsmithing Association, where my artistic background finds an outlet in crafting exquisite jewelry. This role demonstrates my commitment to fostering a thriving artistic community and nurturing the talents of others. My skills as a jeweler serve as a harmonious fusion of my diverse educational background and my artistic inclinations. My jewelry creations reflect a perfect blend of engineering precision, artistic flair, and business acumen.

I’m a  metalsmith working in silver, gold, and luscious stones. I love the process – give me fire and red-hot metal any day.  I also have to keep making jewelry to support my stone-buying obsession.

I love contributing to COMA because I have received so much from them it is time to give back!

Lori Baer
Education Chair

Hello!  My name is Lori Baer.  I am a retired Cartographer from the USGS/Mapping Division at the Denver Federal Center.  I have been a member of CoMA since its first conference, and I have a passion for the knowledge of how things are made!  I started making jewelry and beading with my older sister when I was quite young, and it is still my ‘go to’ hobby, among playing mandolin, quilting, gardening, and mosaicking.  I was Co-Chair of CoMA in 2011-12, and I served on the board three years prior.  I enjoy the jewelry community, artists, and ‘makers’, and I would be happy to participate on the board again as Education Coordinator.  I'm open to all ideas and suggestions as to what we can do to ‘spark’ CoMA's mission in our state and communities.  Truly, the networking aspect of this organization is exceptional, and communication is key, so I would love to create and support events that encourage students and others to participate in this incredibly special nonprofit organization!

I love using different materials in my work to help file through thoughts and arrive at the final concept. I am trained in blacksmithing, metalsmithing, hot glass, and ceramics. I am currently engaged in combining those disciplines into sculptural canvases and forms. Following the completion of my undergraduate degree, I worked as a blacksmith for Geoffrey Newton Metalworks and then as a bench jeweler for Todd Reed in Boulder. I completed my MFA in Metals at Cranbrook Academy of Art and then I moved into a hot glass residency in North Carolina. I grew up in Denver but I now live in Strasburg which is about thirty minutes to the East where a small piece of land affords me a home studio and a micro farm.


I have been a CoMA member off and on since undergrad and I think the Conference draws a spectacular lineup of metalsmiths from around the country. I am volunteering on the CoMA Board because a few years ago I was just moving back to Colorado and I started getting invitations to join different shows through CoMA and it really helped me feel connected to the art scene here again. I hope that as Exhibitions Chair I am able to seek out new opportunities and keep that exciting momentum going within CoMA and for us as members.

Helene Arendt
  • Facebook

Helene is the Artisan behind CSBmetalsmith – The Mountain Metalsmith. Her first mentor, her Opa, a master cabinetmaker from Austria instilled in her to always be inspired by nature and to value precision. Growing up in his Werkstätte, she learned early in life the importance of being meticulous and to always strive to create unique pieces of high quality. She understands the significance of having pride in putting her Mark on her pieces, just as Opa did on his.

Despite working full time in IT, she devotes the remainder of her time to continuing to hone her craft in her own Werkstätte. She is a board member of several nonprofit organizations, however she values her role as Secretary of CoMA most, because she feels strongly about giving back to this community that has inspired her over the years. She enjoys interacting closely with her colleagues which enhances her creative world.

Helene first achieved Roycroft Artisan status in June of 2020, an honor she is proud to have maintained. To remain a Roycroft Artisan in good standing she must continue to follow the rigorous standards of: excellent hand craftsmanship, outstanding design, ongoing artistic development, uniqueness of expression and professional acknowledgement. Doing so allows her to continue to use the Roycroft Mark on her pieces.  She maintains this status by applying each year to be juried by Master Roycroft Artisans and is striving to become a Master Roycroft Artisan herself, which requires at least 5 years of Roycroft Artisan status.

Helene began her self-directed metalsmithing career in 2006 and has participated in classes and studio sessions with Harry Burdette, Travis Ogden, Bill Fretz, Micheal Good, Allison Antelman, Juan Carlos Caballero-Perez and Melissa Muir.

She exhibits her current work at The Kaleidoscope Gallery in Nederland Colorado, The Schoolhouse Gallery in East Aurora NY and The Roycroft Copper Shop Gallery in East Aurora NY.
