In early 2024, Alan co-founded SECTOR, a subscription legal service for public charities, private foundations and impact organizations, offering a flat-rate, fractional General Counsel model with seasoned nonprofit attorneys. Before co-founding SECTOR, Alan founded Frosh Philanthropy Partners, a multi-service advisory firm focused on creating philanthropic legacy and maximizing impact for families and small businesses, and served as the Denver Market Director for Notley Ventures, a family office catalyzing social innovation through the marriage of impact and profit.  Previously, Alan led the acquisition of Tattered Cover Book Store, Denver’s iconic independent bookstore and one of the city’s most prominent small businesses, and served as Program Associate and Senior Fellow at El Pomar Foundation, where he directed several programs and managed the foundation’s grantmaking in Colorado’s High Country Region.   

Alan is a proud three-time alumnus of the University of Denver, maintaining connection to his hometown.   While earning a Bachelor’s Degree and as a member of the Pioneer Leadership Program, Alan continued his service to the city’s nonprofit sector, working in fundraising at Young Americans Center for Financial Education, one of the country’s most innovative and unique nonprofit organizations.  Alan graduated from the University’s Sturm College of Law, with an emphasis on corporate and commercial law, and later returned to the University to join the Daniels College of Business’ inaugural MBA@Denver cohort, graduating with a concentration in Finance.

Alan commits his time, talent and treasure to his community beyond his professional work, serving on many nonprofit boards and advocating for causes close to his heart.  Most recently, Alan served on the Finance Committee for Denver Mayor Mike Johnston’s campaign and on the Mayor’s transition team.  In 2018, the Anti-Defamation League awarded Alan its Daniel R. Ginsberg Leadership Award, “in recognition of exemplary leadership” as a young professional, and in 2021, Colorado Governor Jared Polis selected Alan to serve as a Colorado Governor’s Fellow, one of the state’s most prominent leadership programs.  In 2014, Alan celebrated his 30th birthday with the “Charity Thirty” campaign, raising money for six Denver-area nonprofit organizations.
