Group Sixty was founded in 2010 by Darren Reinke to help clients compete in fast growing, chaotic markets by improving their ability to execute key growth initiatives and by enabling leaders and teams to play to their strengths and adapt to changing marketplace needs.

Darren Reinke, who has both worked and consulted for Accenture and other consultancies, launched Group Sixty as a lean, execution obsessed alternative to the big firms that propose bloated scopes and teams. The company blends leadership development with consulting given his experience in seeing projects struggle due to underdeveloped leaders and under-performing leadership and project teams.

Darren began his consulting career in 1997 at Accenture in San Francisco, CA. At Accenture, he engaged clients to define, develop, and implement business strategies, processes, and information systems. After his time at Accenture, Darren received an MBA from UC Berkeley at the Haas School of Business.  Since he received his MBA, Darren has worked in consulting and leadership development in addition to successfully launching start-ups focused on the outdoor sports vertical. When he is not advising clients, Darren spends time outdoors with his family in San Diego.
