Clare Hefferren, Founder and President of Callosum, puts 30 years of marketing experience to work at Callosum. She began her career in graphic design and rose quickly to the position of creative director, working for marketing communications and dot-com companies in Chicago, Vail, Colorado and San Francisco. In the late 1990s she relocated to Venice Beach, California to become creative director of where her responsibilities included brand consistency following the acquisition of Drawn to L.A.’s apparel industry, Clare shifted her creative insights to fashion. As a senior brand manager at Putnam Sourcing Group in 2004, she guided 17 national accessory accounts. In 2005 Clare became design director for CellKeeper™ where she established the product in domestic and international markets.

The culmination of these interests and skills inspired Clare to develop and launch Callosum in 2005, a purpose-driven brand strategy firm for the outdoor industry.
Equally comfortable in the backcountry and boardroom, she’s committed to doing business for good – people, planet, profit.

Clare holds a bachelor’s degree in sociology from Wittenberg University and a Professional Designate AA in merchandise product development from the Fashion Institute of Design and Merchandising. Her scholarly recognitions include membership in the Phi Theta Kappa Honor Society, a 2003 Product Development Award and valedictorian honors. Clare has been featured on television and in publications around the country. While based in Vail, Colorado since 2010, she travels nationally for client projects and public speaking engagements. Away from the desk, you’re likely to find her on the trails as she’s a sophisticated tomboy.
