The executives will report to Sundance Institute executive director Keri Putnam and will be situated in Park City, Utah.
Hopkins and Pearce will share duties as internal and external leaders of the organization with their distinct areas of responsibility.
Brooke McAffee has been promoted to chief financial officer of Sundance Institute.
The internal promotions take effect on Jan 1 in light of Jill Miller’s imminent departure as MD after more than 20 years with the Institute.
“During their tenures at Sundance Institute, Sarah and Laurie have played critical roles in the success, growth and stability of the organisation,” said Putnam. “We look forward to the deep experience, professionalism, leadership, and continued commitment to the Sundance mission they will bring to their new roles at the Institute.
“As we say goodbye to Jill Miller and recognise her many valuable contributions to Sundance, we are grateful that she has developed and mentored such strong successors.”
