STRATA
STRATA grew out of decades of expertise at Southwest Composite Works, where precision, durability, and innovation have been the hallmarks of every project. Founded by John Groth, a master toolmaker from Milwaukee, Wisconsin, the shop has spent over 30 years crafting high-performance fiberglass and carbon fiber parts for industries that demand excellence. John’s passion for climbing, however, takes that precision outdoors, transforming it into gear that meets the unique challenges of the indoor and outdoor climbing industry.
Over the years, rock climbing has been a pillar of life for John and his family, climbing in the beautiful New Mexican landscapes and spending extensive time in Yosemite Valley, Indian Creek, and destinations abroad. These experiences inspired the philosophy behind STRATA: gear should be durable, high-performing, built to support climbers, and made to respect the landscapes that inspire them.
Today, STRATA channels that family spirit and outdoor passion into every product.
WHO WE ARE
JOHN GROTH
Born in the Midwest, John discovered climbing at Devil’s Lake as a member of the DLFA, where his passion for the outdoors and craftsmanship began to take shape. He later moved to Albuquerque, New Mexico, where he founded Southwest Composite Works more than 30 years ago.
John came up in an era where craftsmanship, hands-on problem solving, and precision were at the heart of manufacturing. A master toolmaker and lifelong outdoor enthusiast, he has spent decades climbing around the world while building a career creating high-performance composite components for demanding industries.
SARAH GROTH
Sarah is a maker, climber, and artist.
Born and raised in New Mexico, Sarah grew up climbing at crags around the world and developed a deep connection to the landscapes, people, and creativity that define the climbing community. That passion has shaped her journey and inspired her to create products that reflect the values she cares about most: thoughtful design, sustainability, and performance.
As a lifelong climber and creative, Sarah brings together her background in art, communication, and outdoor culture to help bring STRATA to life. Alongside her father John, she is building a brand rooted in craftsmanship, innovation, and a belief that climbing gear should be durable, high-performing, and thoughtfully made.
HUNTER CORLISS
Hunter is a climber, skier, and lifelong tinkerer with a passion for the outdoors and building things. His connection to the outdoor world began during a NOLS course in high school, which inspired him to pursue outdoor leadership and mountain guiding in Moab throughout college.
After earning his Master’s degree in Business Administration with a focus on outdoor products, Hunter moved to Albuquerque with his wife, Jordan, and became part of the local climbing community. His passion for climbing, product development, and the outdoor industry led him to Southwest Composite Works, where he joined the team to help bring John and Sarah’s vision for STRATA to life.
Hunter brings a unique blend of outdoor experience, business insight, creative problem-solving, and a growing expertise in design and manufacturing. He is excited to help build durable, thoughtfully designed products that support climbers and the future of the sport.
