Our Founder: Brian Thaler

"From selling disinfectants to leading the way in critical environment cleaning, Brian's career has been a journey of growth and expertise. His humble beginnings in the Northeastern United States, catering to hospitals and pharmaceutical companies, led him to expand his knowledge in biology and bacteria removal. With 14 years at Merck & Co., Inc. and 2 years at Bristol Myers Squibb, Brian honed his skills in managing sales reps and capital products. But it was his time at STERIS Corporation that truly solidified his expertise in infection control, sterilization, and automated washing equipment.

However, Brian's thirst for innovation and improvement led him to a new challenge in 2001. As a General Manager of a satellite office for specialized contract cleaning company, he single-handedly transformed the Bay Area branch from a small team of 12 to a thriving business with 71 employees and tenfold increase in revenue. With a keen eye for quality control and a deep understanding of contamination control, Brian propelled the company to new heights.

But It wasn't until March 2010 that Brian's vision truly came to life. With the launch of nanoCLEAN CE Critical Environments, Inc., he sent out to revolutionize the contract cleaning industry for critical environments. With unparalleled expertise and an unwavering commitment to solving problems, Brian's company has become the go-to source for all critical environments cleaning needs."
