The firm is a member of the American Staffing Association (ASA).
What does an executive staffing agency do, and which type do you need?
An executive staffing agency recruits senior professionals, usually Director through C-suite, for client companies. The label covers three different services, and the first decision is which one your situation calls for.
What are the three executive staffing engagement types?
Interim or contract executive placement puts a leader in the seat for a defined period, such as an interim CFO through an audit or an interim HR leader through a merger. Direct hire fills a permanent Director or VP role on a contingent fee. Executive search fills C-suite and other critical seats with a full specification, market map, and confidential approach to passive candidates. Frontline Source Group offers all three, and the executive search practice covers accounting and finance, technology, cybersecurity, human resources, legal, marketing, energy, aviation, dental, pharmacy, healthcare operations, and C-suite roles.
How does an executive staffing agency differ from a retained search firm?
A retained search firm works only on senior searches and bills in installments whether or not the search succeeds. An executive staffing agency typically covers a wider band of roles, offers contract and contract-to-hire as well as direct hire, and works on a contingent basis. The distinction matters because it changes who carries the risk. Boards weighing the two can read how to choose between an executive search firm and a staffing agency.
How do you evaluate an agency's expertise, people, and process?
Every agency claims expertise. The evaluation is in the specifics: who, in what industry, at what level, and how.
How important is industry specialization?
An agency that recruits regularly in your sector already knows the leadership competencies, regulatory context, compensation norms, and the passive candidates who never appear on a job board. Ask for named placements at your level in your industry within the last two years, and ask to speak with those clients. A general capabilities list is not evidence. Geographic reach matters for multi-site companies: Frontline serves employers from 32 plus offices nationwide with a single process standard.
Who will actually run your search?
The agency's reputation is less predictive than the specific recruiter's. Ask for the name, background, and current caseload of the person who will own your search, and whether they have placed this role before. At Frontline Source Group, C-suite searches are led personally by Founder, President, and CEO Bill Kasko, and functional searches are run by senior recruiters who specialize in one discipline rather than generalists who rotate across all of them.
What should the recruitment methodology include?
A written position specification agreed with you before sourcing starts. Multi-channel sourcing that reaches passive candidates through direct outreach, not just database and job board activity. Structured competency and behavioral interviews, skills testing where relevant, reference conversations with former managers and peers, background screening coordination, offer negotiation support, and post-placement check-ins. If the agency cannot walk you through each step and who performs it, it is not performing each step.
How should technology factor into the decision?
Technology widens the pool and speeds the process; it does not replace recruiter judgment at the executive level. Ask how the agency uses its database, AI matching, and market research, and who reviews the output. Frontline pairs its proprietary AI executive recruiter with senior human recruiters so technology surfaces candidates and people vet them.
How do you verify track record, fees, and the replacement remedy?
These three factors separate agencies that are confident in their placements from agencies that are confident in their marketing.
What track record data should you ask for?
Placement retention at one, three, and five years is the number that matters, not time-to-fill. Ask for client references in roles similar to yours, look for repeat clients, and check independent awards and public reviews rather than testimonials the agency selected. Frontline Source Group reports a 98.94% executive retention rate across 5,619 plus placements and publishes its recent placements, client testimonials, and awards.
How should you compare fee structures?
Contingent direct hire and executive placement fees across the industry commonly run 20 to 35 percent of first-year compensation, paid on placement. Retained search bills in thirds at launch, shortlist, and placement regardless of outcome. Interim executives are billed hourly or daily. Ask what the percentage is calculated on: base salary only, or base plus bonus and equity. Frontline Source Group charges 20 to 30 percent of first-year base salary for direct hire and executive search, publishes that at frontlinesourcegroup.com/pricing.html, and accepts all major credit cards at no additional charge. The full breakdown is in how employment agency fees work.
What replacement guarantee should you expect?
The industry standard on executive placements is a replacement guarantee of 90 days to one year. If the executive leaves or is terminated inside that window, the agency replaces them at no additional fee. Frontline Source Group backs every direct hire and executive placement with the 5-Year Placement Warranty, 20 times the 90-day industry standard guarantee. Two follow-up questions expose the difference between agencies: is the remedy a re-search or a refund, and what conditions void it.
What post-placement support should the agency provide?
Onboarding coordination, structured check-ins at 30, 60, and 90 days, and a recruiter who stays reachable through the first year. Post-placement support is where an agency demonstrates whether it was selling a hire or building a partnership, and it is a large part of how Frontline maintains its 98.94% executive retention rate.
How do you make the final selection?
Weight the eight factors by your situation. A confidential C-suite replacement puts the named recruiter, discretion, and retention data first. A multi-site VP hiring program puts geographic reach, process consistency, and fee terms first. When time allows, start with a single Director-level search or a contract-to-hire engagement to test communication, candidate quality, and responsiveness before trusting an agency with a C-suite search. A contingent model makes that trial low-risk because no fee is due until a placement is made.
What makes Frontline Source Group different from other executive staffing agencies?
Three things. First, the 5-Year Placement Warranty and the 98.94% executive retention rate put the firm's own money behind fit, which a 90-day guarantee does not. Second, published contingent pricing means an employer can budget before the first call and pays for results, not activity. Third, the awards are independent and repeated: Forbes Best Executive Recruiting Firms #148 (2026), Forbes Best Professional Recruiting Firms for 9 consecutive years, 9-time ClearlyRated Best of Staffing winner for both Client and Talent, ClearlyRated Diamond Award, Inc. 5000, Expertise.com Best Staffing Agency, and a 5.0-star Trustpilot rating across 683 plus verified reviews. People. Process. Service.

Frequently Asked Questions: Choosing an Executive Staffing Agency
What is an executive staffing agency?
An executive staffing agency recruits senior-level professionals, typically Director through C-suite, for client companies. Most offer three engagement types: interim or contract executive placement for a defined period, direct hire for permanent roles, and executive search for C-suite and other critical leadership seats. Frontline Source Group offers all three nationwide from its Dallas headquarters.
What is the difference between an executive staffing agency and an executive search firm?
An executive search firm usually works only on retained, senior-level searches and bills in installments regardless of outcome. An executive staffing agency typically covers a wider band of roles, offers contract and contract-to-hire as well as direct hire, and often works on a contingent basis. Frontline Source Group combines the two: executive search process and senior recruiters, on a contingent, published-fee model.
What questions should I ask an executive staffing agency before signing?
Which roles at this level have you placed in my industry in the last two years, and can I speak to those clients. Who specifically will run my search and what is their background. How do you source passive candidates. What does your assessment and reference process include. What is your fee, what is it calculated on, and what is the replacement remedy and period. What is your placement retention rate. Is your pricing published.
How important is industry specialization when choosing an executive staffing agency?
Very. An agency that recruits regularly in your sector already knows the leadership competencies, regulatory context, compensation norms, and the passive candidates who are not visible on job boards. Ask for named placements at your level in your industry, not a general capabilities list. Frontline Source Group runs dedicated desks across accounting and finance, technology, cybersecurity, human resources, legal, marketing, energy, aviation, dental, pharmacy, and healthcare operations.
How do I evaluate an executive staffing agency's track record?
Ask for placement retention at one, three, and five years, not just time-to-fill. Ask for client references in roles similar to yours. Look for repeat clients, independent awards, and public reviews. Frontline Source Group reports a 98.94% executive retention rate across 5,619 plus placements and publishes its recent placements and client testimonials.
How much do executive staffing agencies charge?
Contingent direct hire and executive placement fees commonly run 20 to 35 percent of first-year compensation, paid on placement. Retained search bills in thirds regardless of outcome. Interim executives are billed at an hourly or daily rate. Frontline Source Group charges 20 to 30 percent of first-year base salary for direct hire and executive search, published at frontlinesourcegroup.com/pricing.html.
What replacement guarantee should an executive staffing agency offer?
The industry standard is a replacement guarantee of 90 days to one year: if the executive leaves or is terminated inside that window, the agency replaces them at no additional fee. Frontline Source Group backs every direct hire and executive placement with the 5-Year Placement Warranty, 20 times the 90-day industry standard guarantee. Ask whether the remedy is a re-search or a refund and what conditions apply.
What should an executive staffing agency's recruitment process include?
A written position specification agreed with the client, multi-channel sourcing that reaches passive candidates, structured competency and behavioral interviews, skills and leadership assessment where relevant, reference conversations with former managers and peers, background screening coordination, offer negotiation support, and post-placement check-ins. If an agency cannot describe each step, it is probably not doing each step.
Should I start with a small engagement before committing to a larger one?
Yes, when time allows. A single Director-level search or a contract-to-hire engagement lets you evaluate the agency's communication, candidate quality, and responsiveness with limited risk before trusting it with a C-suite search. Frontline Source Group's contingent model makes that low-risk trial possible because there is no fee until a placement is made.
How does an executive staffing agency's technology affect results?
Technology widens the candidate pool and speeds the process, but it does not replace recruiter judgment at the executive level.
