CSGI DISINFECTS YOUR FACILITIES WITH OUR UV-C ROBOTS.

Clean Sweep Group, Inc. (CSGI) is a company built from decades of hands-on experience inside hospitals, working shoulder-to-shoulder with clinicians, infection prevention teams, EVS staff, and supply chain leaders to solve real operational challenges.

Founded in 2011 by healthcare veterans Leo Williams and Mark House, CSGI was born from a simple but powerful belief: that advanced disinfection and disciplined process execution could meaningfully reduce infection risk. What sets CSGI apart is not just its technology, but the depth of lived experience behind it. Together, the leadership team brings more than 50 years of direct hospital support experience, having operated within some of the most demanding clinical environments in the country.

CSGI’s work is grounded in clinical validation and real-world results. The company has participated in multiple peer-reviewed clinical trials demonstrating significant reductions in hospital-acquired infections (HAIs), including one study where a partner hospital realized over $1.2 million in avoided HAI-related costs. These outcomes are the result of executing proven protocols within the complex realities of active healthcare environments.

Over the past decade, CSGI has successfully deployed its programs across a wide spectrum of settings—acute care hospitals, surgical centers, nursing facilities, and large-scale commercial environments—earning the trust of organizations such as Providence Holy Cross Medical Center, Nicklaus Children’s Hospital, and major health systems across California and the U.S. During the COVID-19 pandemic, CSGI was on the front lines, supporting hospital partners and rapidly expanding its capabilities to meet urgent disinfection demands at scale.

Today, CSGI integrates autonomous UV-C technology with operational expertise, delivering consistent, high-efficacy disinfection while embedding seamlessly into hospital workflows. But beyond infection prevention, the company has evolved into a broader operational partner—helping healthcare systems reduce waste streams, improve sustainability metrics, and unlock measurable cost savings that
directly impact operating margins.

At its core, CSGI understands that hospitals need solutions that work within their environment, align with their teams, and produce quantifiable results. That is where CSGI excels: translating deep clinical and operational experience into programs that deliver safer environments, stronger sustainability performance, and meaningful financial returns.
