About the President
Experienced Leadership and Quality Service
Dan Ellis — President, SEMCO Management, Inc.
Some businesses are built. Others are inherited with purpose. For Dan Ellis, leading SEMCO Management, Inc. is both.
Dan Ellis has served as President of SEMCO Management, Inc. since 2018. He brings more than 25 years of experience in HR, payroll services, accounting, and office administration to the role. But his connection to SEMCO runs far deeper than his title.
A Legacy Built Over Generations
SEMCO Management, Inc. was founded in 1970 by Dan’s grandfather, Leonard Ellis. What began as a forward-thinking workforce management concept grew into a trusted resource for businesses across California and Arizona.
In 1994, Dan’s father, David Ellis, took the helm — continuing the family’s commitment to serving business owners and their employees with integrity and care.
When Dan Ellis stepped into the presidency in 2018, he carried that legacy forward. Three generations. One mission. Helping businesses grow by taking the complexity of workforce management off their plate.
Experience That Goes Beyond the Title
Dan Ellis did not simply inherit a company. He built his expertise from the ground up.
With over 25 years in the industry, Dan brings hands-on knowledge of accounting, HR operations, and office administration to every client relationship. That experience shapes how SEMCO serves its subscribers — with precision, transparency, and a genuine understanding of what business owners face every day.
Under Dan’s leadership, SEMCO continues to deliver the enterprise-level HR and payroll services that small and mid-sized businesses need to compete and grow.
