About LaSalle

LaSalle Network is a staffing, recruiting and culture firm.

LaSalle Network was founded in 1998 under the belief that if we hired great people, trained and developed them, the end result would be outstanding service to our candidates and clients. After two decades of service and countless culture and industry awards, we’ve realized one thing to be true: a great culture results in stellar delivery. We are proud to be one of the country’s best staffing agencies. As our business has grown, we’ve expanded to new markets and new service offerings. We continue to change and improve so we can help our clients achieve their goals and vision.


At LaSalle, we value our people so we can care about yours.

Our mission is to build relationships to help organizations hire faster and connect qualified talent with opportunities.
