What Isaacson, Miller does
Isaacson, Miller is a privately held executive search firm founded in 1982 by John Isaacson and headquartered in Boston, Massachusetts, specializing exclusively in leadership recruitment for mission-driven organizations across the civic sector. The firm operates through a six-phase search process — definition, candidate discovery, screening, assessment, selection, and transition support — and conducts approximately 500 searches per year across 12 vertical practices including Higher Education, Healthcare and Academic Medicine, Arts and Culture, Environment and Conservation, Philanthropy, PreK-12 Education, Social Justice and Advocacy, and International engagements. It leverages a proprietary database of more than 760,000 individuals and the Hogan Assessment methodology for leadership evaluation, with 250+ specialized professionals delivering engagements across all 50 U.S. states, the District of Columbia, and 26 countries.
The firm's revenue is generated entirely through professional services fees tied to retained executive search engagements, with quote-based pricing tailored per assignment; pricing is not publicly disclosed. Its go-to-market is relationship-based, enterprise field sales driven by repeat institutional clients — 83% of 2025 searches were for returning organizations, with 92% retention in higher education and 87% in healthcare. Beyond core search, Isaacson, Miller operates a complementary advisory offering, Academic Strategic Advisors, co-developed with strategy consultancy Ad Verum Partners and former provosts of Duke and Yale, providing strategic priority alignment, organizational restructuring, budget model analysis, and executive coaching to academic leadership clients.
Isaacson, Miller reports 99% client referral satisfaction and claims that 45% of executive leaders at top academic medical centers are firm placements. The firm remains founder-influenced: John Isaacson serves as Chair, Ericka Miller as President and CEO, with multiple Managing Partners and Practice Leaders heading sector-specific practices. It is privately held with no parent company, no external investment, and no public listing, and it has not disclosed revenue or pursued funding events.
