The 5 best nonprofit recruitment firms for executive search in 2026

A nonprofit recruitment firm finds your next executive director or CEO. It works out what the job needs, tracks down people already doing that job elsewhere, and gives your committee a short list to interview. You are paying for the search itself, so the fee is owed even if you hire nobody from that list.

Two things make this different from hiring at a company. The money comes out of your program budget, so the board questions every dollar. And a volunteer committee makes the decision, not one manager, and it meets once a month.

So the right firm depends on your size. Big institutions want a big name. A mid-sized nonprofit wants a fixed fee it can budget, someone who keeps a volunteer committee moving, and support for the new leader once they start.

We compare five firms below on the eight questions your board should ask before it signs. Figures are what each firm published as of August 2026.

What to look for in a nonprofit recruitment firm

All five of these firms will bring your board a shortlist. What separates them is how the search is run, what it does to your budget, and what the firm is still responsible for once your new leader starts. These eight questions will tell you most of what you need to know about any firm on this list.

• How the search connects to your talent plan. A search can be a single transaction or one step in a plan that also assesses, develops, and keeps the person. A search-only firm hands your board a hire and closes the file. A connected firm still has a stake in how that leader is doing in month nine. Decide which one you are buying, because it decides who owns the outcome after the offer is signed.
• How results are measured. Ask what the firm can show you: a client satisfaction score, how often clients come back, how many placed leaders are still in the seat two years later. A firm with numbers has been counting. A firm without them is asking you to treat references as evidence.
• Fee structure and total cost. Most retained search is priced as a percentage of the hire’s first-year total compensation, typically 25 to 33 percent. That does two things to a nonprofit. The fee climbs with the salary you are negotiating, and you cannot put a firm number in the budget before the search starts. A flat fee agreed up front removes both problems. Ask which model you are being quoted, before the first proposal.
• Who runs the search day to day. Firms sell the search with a senior consultant and sometimes hand the calling and screening to a research team. Ask who reads the market and speaks to candidates, by name, and how often your committee will hear from them. A volunteer board that gets an update once a month loses momentum, and momentum is most of what keeps a good candidate in a process that runs for five months.
• Experience with boards and search committees. A corporate search answers to one person. Yours answers to a group of volunteers who hold different views of what the organization needs, several of whom will meet the candidates once. A consultant who has sat on a nonprofit board knows how that room works: how to build a scorecard the committee agrees to before it sees anyone, and how to keep a dissenting trustee inside the process.
• Mission and sector fluency. Running a $30 million nonprofit is a different job from running a $30 million company. Your executive director has to raise the money before they can spend it. They answer to a board of volunteers rather than to one boss, they meet the conditions attached to every grant, and they hold on to staff who could earn more elsewhere. A firm that mostly recruits for companies will judge candidates on how well they run a business, which is not the same thing. Ask how many searches the firm has run in your sector in the last two years, and for two references from them.
• Diverse slate track record. Most firms state a commitment. Fewer publish what came of it. Ask for two numbers: the share of placements in the last three years who were people of color or women, and the share of candidates presented on slates. The gap between those answers tells you whether the commitment operates at the sourcing stage or only in the proposal.
• What happens after placement. One in three nonprofit leaders say they are likely to leave their current position within two years, according to the Chronicle of Philanthropy’s survey of nonprofit chief executives. Your risk does not end when someone signs. A firm that onboards and coaches the new executive is protecting its own placement. A firm that stops at the offer letter leaves that risk with the board, which is the group that pays for the next search.

On three of these eight questions, the same firms come out on top every time. Isaacson, Miller publishes satisfaction and repeat-client numbers nobody else here can match. Koya Partners publishes a diversity figure nobody else can match. And on sector knowledge, Isaacson, Miller has run more than 10,000 civic-sector searches and WittKieffer has worked in healthcare and education since 1969. A smaller firm has not seen that many versions of your search.

The other five questions are the ones that decide a mid-sized search: what the fee does to a budget your board approved months ago, who actually works the search week to week, whether the firm can hold a volunteer committee together for five months, whether the search connects to anything that happens after it, and who is still accountable when the new executive reaches month nine.

1. LAK Group

LAK Group is a US human capital firm that works across the whole talent lifecycle: assessment, hiring, leadership development, coaching, succession, and outplacement. Its nonprofit executive search practice sits inside that, which is both the argument for hiring them and the reason they are the odd name on this list. Every other firm here is a search firm and nothing else.

What LAK Group does well

The fee is flat and it is set before the search starts. LAK quotes a retained flat fee based on the complexity of the assignment, not a percentage of what the hire ends up being paid. The cost does not climb with the salary you negotiate, and nobody advising on that compensation conversation has an interest in the number going up.

The people running the search have sat on the other side of the table. LAK’s nonprofit consultants are trained in board governance and serve as board directors themselves, so they know how a search committee behaves: which trustee goes quiet, and how to hold a decision together across the month between meetings.

Every search gets a dedicated research associate, working to a plan your committee agrees in the first few weeks. Finding candidates is that person’s whole job on your search, not something fitted in between other assignments. That is what puts strong people who were not job hunting in front of your committee, instead of only the people who saw the posting and applied.

The process is built to end in a decision, not a shortlist. A scorecard goes to the interview panel that benchmarks the competencies the board agreed on at the start, so volunteers who disagree about a candidate disagree against a shared standard. That is what stops a search stalling between two finalists.

The work continues after the hire. Transition discussions are part of the search, and the same firm can add executive coaching, assessment, and leadership development for the new executive and the team under them. Your board gets one point of accountability instead of a search firm, a coach, and a consultant pointing at each other.

Where LAK Group falls short

Nothing is measured in public. LAK publishes no client satisfaction score, no repeat-client rate, and no retention figures for the executives it has placed. Isaacson, Miller publishes the first two, so if your board wants to compare firms on published numbers, that is a real difference between them. Ask LAK for retention data on recent placements in the first meeting.

The diverse slate commitment does not come with a number. LAK commits to presenting a diverse slate in every search, and Koya Partners publishes that 85 percent of its 2021 and 2022 placements identified as women and/or people of color. If a published track record is what your board needs to see, Koya has one and LAK does not.

Best for

A mid-sized nonprofit hiring an executive director or a chief officer, that wants a fixed fee it can budget, a firm that can run a volunteer search committee, and coaching and development for the new leader in the same relationship.

2. Isaacson, Miller

Isaacson, Miller was founded in 1982 and works only in what it calls the civic sector: universities, academic medical centers, foundations, arts organizations, PreK-12 education, conservation groups, human service agencies, and advocacy organizations. It is a 100 percent employee-owned corporation with more than 250 professionals and over 10,000 searches behind it.

What Isaacson, Miller does well

The firm publishes numbers, and the numbers are strong: a 99 percent client satisfaction score and an 83 percent client return rate. No other firm on this list publishes both, and a repeat rate that high is hard evidence, because it means boards that have been through the process hire them again.

The sector coverage is unusually complete. Eleven market practices span most of what the independent sector contains, and board searches and chief diversity officer searches are named practices rather than favors attached to a bigger assignment.

Employee ownership changes the incentives. The consultants own the firm rather than working to a parent company’s quarterly number, which is part of why taking an extra two months to get a president search right is a decision the team is free to make.

Where Isaacson, Miller falls short

The engagement is a search and it ends at the placement. No onboarding, coaching, or leadership development is advertised as part of the offering as of August 2026, so anything your new executive needs after the start date is a separate purchase from a different firm.

Fees and guarantee terms are not published, so a board cannot approve a search budget before it has committed to the search.

Most of the published work sits at large institutions, so a $10 million agency is a smaller assignment inside a firm built around bigger ones. Ask who would staff your search and what else is on their desk.

Best for

A university, academic medical center, or large foundation that wants a firm devoted entirely to the civic sector, with published evidence that its clients come back.

3. Koya Partners

Koya Partners is the nonprofit and social impact practice of Diversified Search Group, which acquired it in 2019 and now brands it DSG | Koya. It works across nine mission-driven sectors including foundations and philanthropy, arts and culture, social justice and advocacy, and social services, and it recruits executive directors, CEOs, senior functional leaders, and board members.

What Koya Partners does well

The diversity record is published, and it is the strongest on this list. 85 percent of the practice’s placements in 2021 and 2022 identified as women and/or people of color. This is a genuine strength. On the question of whether a stated commitment actually changes who ends up in the role, Koya Partners answers it better than anyone else here, LAK Group included.

Mission-driven work is the whole business, not a practice inside a commercial firm. The consultants spend all of their time in philanthropy and social impact, so the people they can call for an honest reference have run the same kind of organization you are hiring for.

Koya also sits inside a larger group. Being part of Diversified Search Group means a search can draw on a wider research bench than a standalone boutique of the same size could offer.

Where Koya Partners falls short

Nothing after the placement is published. The offering is search. Onboarding, coaching, and development for the new executive are not advertised as part of it as of August 2026, so the first year in the seat is your board’s problem again.

There is no satisfaction score, retention figure, or fee schedule. The published evidence is a list of more than 400 placed leaders, which shows range but does not tell your board how many of them are still in the role.

The sector list is narrower than it first looks, leaning toward philanthropy, advocacy, and social impact. If you are a membership association, a healthcare nonprofit, or a faith-based agency, confirm you are in the core market before you sign.

Best for

A mission-driven organization for which a published, verifiable diversity track record is the first requirement, particularly in philanthropy, advocacy, or social impact.

4. WittKieffer

WittKieffer has been in executive search since 1969 and works in what it calls the quality of life ecosystem: healthcare, education, and life sciences. It has more than 300 team members from Los Angeles to London, and it sells executive search, interim leadership, and leadership advisory.

What WittKieffer does well

Inside healthcare and higher education the sector knowledge is very hard to match. The firm began in nonprofit healthcare search more than fifty years ago, so a health system or university board is hiring a team that has run this exact search many times.

WittKieffer sells more than the search. Interim leadership means a board facing an eight-month vacancy can put an experienced executive in the seat rather than asking a deputy to absorb it, and leadership advisory means the permanent hire can be assessed and supported afterward. No other firm in this comparison offers an interim option.

The firm describes its model as boutique attention at global scale, and for a mid-sized health or education nonprofit that is closer to what you need than a global generalist.

Where WittKieffer falls short

Outside healthcare, education, and life sciences, WittKieffer is a poor fit. An arts organization, a conservation group, or a human services agency is not in the ecosystem the firm has built itself around, and you would be buying its process rather than its network.

Leadership advisory is a separate engagement. It exists, which most search firms cannot say, but it is invoiced separately rather than covered by the search fee.

No fees, satisfaction scores, placement counts, or diversity figures are published, so a comparison against the firms that do publish comes down to references.

Best for

A health system, academic medical center, university, or life sciences nonprofit that wants deep sector expertise, and the option of an interim leader while the search runs.

5. Russell Reynolds Associates

Russell Reynolds Associates is a global leadership advisory firm with an estimated $500 million-plus in revenue, more than 1,900 staff, and offices in over 45 cities. Its social impact practice serves philanthropic, arts and culture, advocacy, membership, and educational institutions globally.

What Russell Reynolds does well

Reach is the product. If your board wants a candidate who currently runs a comparable institution on another continent, this is the firm on the list that can find and approach them without handing the work to an affiliate.

The search is only part of what Russell Reynolds sells. Leadership assessment, board advisory, and CEO transition support sit alongside it, so a foundation that needs its board reshaped as well as its chief executive replaced can buy both from one firm.

The firm is fast for its size, stating that its search process can identify C-suite candidates in as little as 14 weeks. That is the only time-to-fill figure any firm here publishes.

Where Russell Reynolds falls short

The fees are high enough to be prohibitive for smaller nonprofits. The firm is built around large mandates, and a smaller search can sit behind a marquee one, so ask where your role ranks in that team’s current workload before you sign.

Nonprofit work is one practice inside a commercial firm. Social impact is a real practice rather than a brochure, but the firm’s economics are set by corporate search, and your volunteer committee will be working with a team whose week also contains a public-company CEO hire.

Onboarding and activation are sold separately. They exist, which is more than most, but they are a second engagement and a second invoice.

Best for

A large foundation, national institution, or global nonprofit running a high-profile search that needs international reach and board advisory in the same engagement.

Which nonprofit recruitment firm is right for you?

If your board wants published evidence before it signs anything, Isaacson, Miller is the firm with numbers: a 99 percent satisfaction score and an 83 percent client return rate, behind more than 10,000 searches in the civic sector.

If a verifiable diversity track record is the first requirement, Koya Partners publishes 85 percent for 2021 and 2022, and nobody else here publishes anything comparable.

A health system, academic medical center, or university will find WittKieffer’s sector depth hard to beat, and the interim leadership option matters when the seat cannot sit empty for eight months.

Russell Reynolds Associates suits a national or global institution that needs reach and board advisory in one engagement, and can carry the fee that comes with them.

And if you are a mid-sized nonprofit, finding a good candidate is the easy half. What decides whether this hire works is whether the fee fits a budget your board approved months ago, whether someone can hold a volunteer committee together for five months, and who is still accountable when the new executive reaches month nine. That is what LAK Group is built for. If your board is preparing to open an executive search, book a conversation with LAK Group to talk through the process and what the fee would look like.

FAQs

How much do nonprofit recruitment firms charge?

Most retained search is priced as a percentage of the hire’s first-year total compensation, typically 25 to 33 percent. On a $150,000 executive director role that is roughly $37,000 to $50,000, and it rises if the salary does. Some firms, including LAK Group, quote a flat fee instead, set at the start on the complexity of the search, which lets a board approve a fixed number before the work begins. None of the other four firms here publish a fee schedule.

How long does a nonprofit executive search take?

None of the five publish an average. Russell Reynolds Associates is the only one to state a target, saying its process can identify C-suite candidates in as little as 14 weeks. What moves your date most is not the firm, it is your committee’s calendar, because a group that meets monthly adds weeks between every decision point. Ask each firm for the elapsed time on their last three searches in your sector.

What is the difference between a retained search firm and a contingency recruiter?

Retained means you pay across the engagement whether or not a hire is made, and the firm works the role exclusively. Contingency means you pay only when someone starts, and several agencies may be working the same job at once. Every firm on this list is retained. An executive director search is confidential, runs for months, and involves people who are not applying for anything, which is not what a pay-on-placement model funds.

How does a search firm work with a volunteer board or search committee?

The good ones start by interviewing the board and the senior staff separately, because the two groups usually disagree about what the role needs and it is cheaper to find that out before anyone is approached. During the search the firm manages the committee’s calendar, prepares the interviews, and hands the group a scorecard that benchmarks the competencies everyone signed off on, so the finalist conversation is about evidence rather than about who liked whom.

Which nonprofit recruitment firm is best for a mid-sized organization?

The national specialists and the global firms are built around large institutions, so a mid-sized nonprofit often pays for reach it will not use and waits behind bigger assignments. LAK Group is built for the middle: a flat fee a board can budget, consultants who have served on nonprofit boards themselves, and coaching and development available for the leader after they start. If your real worry is not finding a good candidate but keeping one, weight what happens after the placement more heavily than the size of the firm’s network.
