ZRG acquires Sterling Martin Associates to expand nonprofit search practice

What's the deal? ZRG, a global talent advisory firm, has acquired Sterling Martin Associates, a Washington, DC-based executive search firm that specialises in professional associations, trade organisations, and mission-driven nonprofits. The deal expands ZRG's Education, Nonprofit & Social Impact (ENSI) practice.

Sterling Martin was founded by David Martin in 2006 and has advised organisations including the National PTADealroom has a profile for this one.

Martin will join ZRG as managing director, along with a team spread across Washington, DC, Chicago, and Denver.

Why now? ZRG has been on a disciplined acquisition streak, and the nonprofit and association sector presents a growing need for specialised leadership advisory. Associations and mission-driven organisations face unique governance challenges — balancing industry influence with organisational stewardship — that demand deep sector expertise.

"Sterling Martin brings earned credibility in sectors where leadership decisions carry lasting consequences," said Larry Hartmann, chief executive officer of ZRG.

What could go wrong? Sterling Martin is known for a highly personalised, high-touch approach. Integrating that boutique model into a larger global platform risks diluting the relationships and trust that made the firm valuable in the first place. Client continuity will be the key test.

The signal: ZRG, classified as a late-growth-stage firm on Dealroom, is using acquisitions to deepen vertical expertise rather than simply expand geographic footprint — a playbook increasingly common among scaled talent advisory platforms. The nonprofit and association niche, where clients like the National PTA (the largest volunteer child advocacy association in the US) set the tone, rewards long-tenured relationships over transactional reach, making bolt-on acquisitions of trusted boutiques one of the few viable paths to credibility.
