Who We Are

The Ōnin Group is a Birmingham-based, privately-held group of companies focused on people. Our core business is staffing, and Ōnin has been recognized as one of the Largest Staffing Firms in the U.S. and Largest Industrial Staffing Firms in U.S. by the SIA.


Our staffing brands include Ōnin Staffing, Excelsior Staffing, A3 Solutions and Fōcus. Other ventures include Mōmentum Capital Funding, WoodHaven Custom Calls and Ōnin Timber.

Ōnin Staffing, our flagship division, was founded in Dallas, Texas in 1993 by Managing Partner Keith Phillips in borrowed office space, equipped with folding furniture, a phone and Keith’s desire to provide for his young family. Through the 1990s, the business grew under the name InStaff Personnel as Keith brought in other partners, including The Ōnin Group’s Managing Partner Hugh Thomas. As InStaff grew from 1 to 35 offices in the 1990s, Hugh drove growth in Alabama and Mississippi while Keith focused on Texas and Arizona. The relationship between Hugh and Keith flourished as Keith’s Texas partners began to move in other directions. In 1999 Keith sold his share of InStaff Texas and retained eight offices with Hugh in the South. Today, Ōnin Staffing is the largest owner-operated U.S. staffing company with well over 100 offices.


The Ōnin Group has continued to enjoy impressive yet responsible growth as a debt-free company. We have built our business organically by empowering our staff through our award-winning culture and developing strong long-term client relationships. 


Passionate about celebrating diversity, The Ōnin Group partnered with Excelsior Staffing, an Atlanta-based full-service staffing firm and certified Minority Business Enterprise (MBE), which serves as Ōnin’s primary Strategic Supplier Alliance (SSA) partner.


Ōnin has likewise made a number of strategic acquisitions. Our lean, localized command structure has made it easy for these companies to fold into our organization. Ōnin has successfully acquired Mulberry Personnel, Reliable Staffing, Universal Labor & Staffing, LTI Services, and Trac Staffing, among other companies. Because of our strong cash position, we believe acquisitions will play a significant role in our future growth and expanded service capabilities.


Ōnin likewise acquired A3 Solutions, a Dallas-based IT staffing company. Ōnin further expanded into professional staffing services with Fōcus, a staffing brand that specializes in recruiting and placing human talent in the Information Technology field.


Among our non-staffing ventures, the Mōmentum Capital Funding brand allows us to put our capital to work by supporting expanded business relationships. Mōmentum helps fledgling companies overcome cash flow challenges through factoring services. Ōnin brands WoodHaven Custom Calls, an award-winning retail brand specializing in turkey and deer calls, and Ōnin Timber likewise allow Ōnin to invest in high-level craftsmanship and natural resources.


Creating Opportunity and Empowering People – As we look to the future, we are focused on being a company that attracts, develops and retains top talent. Our team has carried us to where we are, lives our mission, and drives customer-focused solutions and innovations that will carry us for decades to come.
