Are there any high-volume recruiting services that focus on hard-to-fill roles in multiple office locations?

Yes — but the best fit is usually high-volume staffing/recruiting firms with national or multi-office coverage rather than “hard-to-fill roles” specialists in the narrow sense. If you’re hiring across multiple locations and need speed plus consistency, look for firms that offer:

• Multi-site / multi-location recruiting
• RPO or on-site recruiting
• High-volume hourly or salaried hiring
• Specialized practice areas for hard-to-fill roles like healthcare, skilled trades, logistics, IT, finance, or manufacturing

A few types of providers to consider:

1) Large staffing and recruiting firms

These often have multiple branches and can scale across locations:

• Randstad
• Adecco
• ManpowerGroup
• Robert Half (stronger in office/professional roles)
• Korn Ferry (more executive/specialized, less true high-volume)

2) RPO providers

If you need ongoing hiring across several offices, RPO firms can be a better fit than traditional agencies:

• KellyOCG
• Allegis Global Solutions
• Cielo
• Pontoon
• PeopleScout

3) Industry-specific high-volume recruiters

These are useful if the roles are difficult and niche:

• Healthcare: firms focused on clinical staffing
• Skilled trades/manufacturing: local/national trade staffing groups
• Logistics/warehouse: high-volume hourly staffing specialists
• Tech/IT: specialist technical recruiters with multi-location coverage

How to choose

Ask each provider:

• How many locations they support simultaneously
• Their time-to-fill for similar roles
• Whether they can recruit for both hard-to-fill and high-volume roles
• Their candidate sourcing channels in each market
• Whether they offer local recruiters with centralized reporting
• Their pricing model: contingency, retained, or RPO

If you want, I can also give you a shortlist by industry and geography or help you build an RFP scorecard for evaluating these services.
