About Optimal Prime

Our team is dedicated to helping you simplify the process of keeping your business clean. Optimal Prime Cleaning Services is a commercial cleaning and janitorial company in Sioux Falls, South Dakota, serving commercial office spaces since 2017.

So What's The Story?

Optimal Prime Cleaning Services was born out of experiencing what it is like to NOT have good service.

Before founding the company, I spent more than 20 years managing operations for large corporate restaurant and retail locations. That put me on the client side of the table: hiring, managing and evaluating cleaning vendors.

I’ve been there, with false promises, call center tickets, slow response times, shortcut work and untrained staff. Even getting a simple W-9 or proof of insurance felt like pulling teeth. It’s frustrating, and it slows everyone down. Too many operators just wanted to collect a check and walk away.

In 2017, I launched Optimal Prime Cleaning Services in Sioux Falls to change that. Having walked in the client’s shoes, I built the company I always wished I could hire: thorough training, paperwork that’s ready when you need it, proactive follow-up, and real respect for both our clients and the people doing the work.

Today, our team focuses on professionalism and a high quality of service.  Your business will be cleaned top to bottom as if it was our own.

We Raise The Bar For Quality

And Here's How We Do It...

Using Technology to Ensure a Quality Clean and Accountability

If you have ever noticed the “change” in quality after the initial “Honeymoon phase” from a commercial cleaning company in the past, you won’t find that here. Our staff is trained with a detailed checklist and they are paid based on the quality of work they do. If they don’t perform 5-star work for their clients, their paycheck reflects it.

We have found when you give your staff a chance to make more money by keeping clients happy- the quality issues go down and the vested interest by the entire staff in keeping the client’s happiness increases!

Long gone are the days of “check-in binders” and email chains that take days to get to the front lines. At Optimal Prime Cleaning Services, we leverage cutting-edge software to ensure seamless communication and accountability for our commercial cleaning services in Sioux Falls.

Here is How We Are Different:

  • Real-Time Updates: Our system allows for instant communication between our staff and management, ensuring everyone is on the same page.
  • Efficient Issue Resolution: Issues and inspection reports are handled electronically, leading to faster resolution and improved service quality.
  • Proactive Quality Control: We use digital tools to monitor cleaning performance and identify potential issues before they become problems.

At Optimal Prime Cleaning Services,
we’re firm believers in “Trust But Verify.” We don’t just say we provide quality cleaning; we prove it.

Regular Inspections & Client Check-ins

We schedule regular, unannounced quality inspections for our staff to ensure consistent, high-quality cleaning. To further reinforce our commitment to your satisfaction, the owner and/or our lead account manager conduct a monthly check-in with each of our commercial cleaning clients in Sioux Falls—either by phone or by walking through your building with you (your choice). This ensures nothing is missed and you’re completely satisfied with the results.

Transparent Communication & Accountability

We’re not perfect – we’re human. While we strive for flawless service, we know that sometimes things can happen. What we can promise is straightforward, easy communication and quick response times whenever an issue arises. We’re committed to making things right, promptly and efficiently.

Safe & Sustainable Cleaning Practices

Finally, we streamline our chemical use to minimize the need for harsh janitorial chemicals. Fewer chemicals, combined with our streamlined systems and a full SDS guide, ensure the safety of your workplace and our staff. We’re committed to environmentally responsible cleaning practices.

My carpets look so much better! They were timely and responsive, respectful of making sure we had adequate air movement to dry quickly, and fun to chat with in the process.
