ASI Employer Solutions & All Staffing Inc. is your single-source solution for all your PEO and ASO needs ranging from payroll processing to human resources support.

ASI Employer Solutions and All Staffing, Inc.

One Company, Multiple Solutions. All Staffing, Inc. orginially began as a payroll processing company based out of Pennsylvania. Looking to expand our services, we remodeled as a Professional Employer Organization (PEO). With much success using this business model in the Northeast, we continued to expand to multiple states. In 2007, we opened an office in California and offer services as an Administrative Services Organization (ASO). Operating under the name ASI Employer Solutions, we can offer several levels of support for all your administrative needs.

Our Mission: To increase profitability for small businesses by consolidating human resources, payroll, workplace safety, benefits and unemployment compensation management into one single-source solution.

Established in 1991, All Staffing has quickly grown into a multi-faceted organization. Our staff manages several regional offices with clients in multiple states. ASI management is a diverse group of professionals including a certified public accountant, OSHA certified safety professionals, advanced degree human resource personnel, and a host of people with experience in handling business problems for our clients. This team not only has overseen the growth of All Staffing and ASI Employer Solutions, but has been at the forefront in the development of legislation and regulations proposed to allow business owners to take full advantage of what we have to offer.
