Our Story
Built on decades of real business experience
STS Services Group LLC was founded on a simple idea: businesses deserve a services partner who understands operations from the inside out. Our CEO, Jemma Sarkissyan, has been working in this field since the early 2000s.
The journey
From the early 2000s to today
What started as hands-on work in business operations and client service grew into a mission: give companies across the country a reliable partner for the work that keeps them moving.
We do not chase trends. We focus on the fundamentals — clear communication, smart processes, dependable people, and results you can measure.
Early 2000s
Where it began
Jemma Sarkissyan began working in business operations and client service, learning firsthand what growing companies need: reliable people, clear processes, and a partner who actually follows through.
2000s–2010s
Years of hands-on experience
Across two decades, she supported businesses in staffing, administration, operations, and management — building the practical expertise that now shapes every STS engagement.
Today

That experience became STS Services Group LLC: a nationwide business services firm helping companies operate better through consulting, operations support, staffing, and administrative services.

Built to adapt
From one-time projects to ongoing partnerships, we adjust our services to fit your business instead of forcing your business into a template.

Why STS
Real experience. Real accountability. Real results.
Many firms offer business services. Few are led by someone who has spent decades doing the actual work. At STS Services Group LLC, that hands-on background shapes everything we recommend and every service we deliver.
We do not disappear after a meeting. We stay engaged, communicate clearly, and measure our success by the progress our clients make.
Looking ahead
