Our Founder - Terry Hookstra
Terry Hookstra, from his humble beginnings, growing up above a bar in Omaha, serving his country in the Navy, and then starting his young career in the computer industry, Terry has always been a forward thinker. For his first entrepreneur journey, Terry created a small computer company. One of his clients was a PEO. After discovering the uniqueness of the PEO industry, he took the challenge of developing a client base for this PEO. After accomplishing this goal, Terry decided to use his entrepreneur skills again and created eEmployers Solutions, Inc. in 1998.

Our Mission Is
To Simplify The
Employment Challenges
of Your Business
At ESI, we specialize in providing comprehensive Human Resource solutions including Workers’ Compensation and Risk Management, Employee Benefits, Retirement Packages, Payroll Administration and more. We offer two ways to access our services: as a PEO (Professional Employer Organization) or as an Administrative Services Organization (ASO).
As a PEO, we enter into a detailed Customer Service Agreement and become a co-employer, taking on most employment liabilities and compliance issues, as well as providing full-service benefit, payroll, and tax management.
Alternatively, as an ASO, we offer a simple fee-based menu of options, from payroll processing to tax filing to benefits administration. However, with this method, your organization retains all liability and responsibility for Workmans’ Comp and other issues.
Our goal is to save you time and overhead, allowing your personnel to focus on growing your business. With headquarters in San Antonio, Texas, ESI has been providing Human Resource Management services since 1999 as a licensed PEO.
