This is our story. Where a mission to create healthy and safe indoor environments started with a team of 2 working from a Louisville, Kentucky basement. With $30,000, passion, grit, and hard work, Kyle Hoylman and Jeff Sims established Protect Environmental.
A lot has changed in the 15 years of Protect Environmental. We have grown since 2005 to a $35 million company with more than 200 employees now providing our professional radon testing and mitigation services in all 50 states and 2 U.S. territories. In honor of wrapping up our 15th year providing expert service from trusted professionals, this is our story of how we got here. And to quote The Grateful Dead in their song Truckin “What a long, strange trip it’s been.”
Where It All Began
Kyle Hoylman was working in the real estate business having started a data mining company specializing in real estate listings operating from 1991-2003(?). Hoylman had never heard of radon before a seemingly random conversation over dinner with a science professor. Intrigued, Hoylman went to work researching radon gas.
In testing his childhood home, he was shocked to find radon gas levels of 83 pCi/L on the main level. This result was way above the EPA action level of 4.0 pCi/L. Within months after this discovery, Hoylman’s father was diagnosed with stage 4 lung cancer as a healthy and active never-smoker. Hoylman was also diagnosed with cancer within a couple months of his father’s diagnosis.
The radon mitigation business model was always more than just a way to make money, it was a way to save lives. With the tragic loss of his father in 2009 and his own battle with cancer, the fight against radon became personal.

Jeff Sims came from a background in car sales and had years of experience in customer service, management, and business. Sims had also never heard of radon gas before he was approached by Hoylman to take on this business venture together.
The company was founded in 2005 by Jeff Sims and Kyle Hoylman where the two worked out of Sims’s basement in Louisville, Kentucky. “We were unfamiliar with the radon industry and decided to take a leap of faith to start a radon mitigation company and expand as we learned.” said Sims.
Uncharted Territory
Originally, Protect Environmental started as a home inspection company before pivoting to become one of the first companies to specialize in radon mitigation in the Louisville, Kentucky market.
The radon industry in 2005 was still new and widely unknown. Therefore, there was not a lot of research or information out there to guide them. Sims and Hoylman decided to roll up their sleeves and try their hand in this open and evolving industry, to be key players in shaping it from Kentucky and beyond.
Breaking Ground
The first job Protect Environmental completed in 2005 took place at a residential home in Louisville, Kentucky. In those early years, Kyle and Jeff completed the installations themselves, and continued to do so until the first crew was hired.
The team of two eventually grew to add Sims’s sister and Hoylman’s partner, Jennifer Sims, as the receptionist and office manager. Today, Jennifer leads the company’s consulting department as the Director of Consulting. The original mitigation team was a three-man crew. Two of the three crew members, Doug Webster and Greg Turner, are still with the company today.
"Protect Environmental is truly a family and it is overwhelming to think how much we have grown as a team and learned about this industry over the years.”
- Doug Webster, Residential Project Manager
After working in Sims’ basement for about 6 months, the team moved to their first office located on Shepherdsville Road – a family-owned property that Hoylman and Sims were allowed to use until they got on their feet.
The company remained at this office for about 8 years until they relocated to their current headquarters on Bluegrass Parkway in Louisville, Kentucky. Business was booming after just three years of building the company name and spreading awareness in the Louisville and Lexington, Kentucky markets. The crew grew from three men to about 15 in just a few short years.

It has grown into a strong and successful company, made up of great, hard-working people. To be a part of Team Green is to be a part of a family.
