Re-Thinking Safety

Traditional safety programs often try to control worker behavior, assuming work is predictable. In tree work, it never is.

Crews climb with chainsaws, operate near live power lines, and adapt to changing conditions every second. Every tree brings new challenges. 

Lewis takes a different approach. We learn from everyday work.

Safety lives in the routine: the miles traveled, the trees removed, and the countless Jobs Done Right®. That is where insight and improvement thrive.

With more than 20 years of experience in safety, human performance, and process improvement, our VP of Safety and Human Performance, Alaina Zieglar, champions a culture where one empowered voice can change everything.

Committed To Safety

Keeping the Power On—Safely and Reliably

Every day, Lewis helps keep the power on for millions of people across the country. With more than 4,000 employees working in 30 states, we support utilities of all sizes that serve over half of the U.S. population—powering homes, businesses, hospitals, schools, and communities that depend on reliable electricity.

In today’s connected world, electricity is essential. It fuels how we live, work, communicate, and care for one another. That’s why our customers trust Lewis to deliver critical infrastructure services with precision, accountability, and an unwavering commitment to safety.

Safety is not a slogan at Lewis—it’s how we operate. It's also our commitment to finish each day injury and incident free. Achieving that requires a best-in-class safety culture backed by continuous training, innovation, and investment.

At Lewis, we combine proven safety programs, advanced technology, and well-maintained equipment with a strong Environment, Health, and Safety (EHS) framework and human performance principles. This proactive approach helps us reduce risk, protect our people, and deliver consistent, high-quality results for our customers.

As demand for reliable power continues to grow, Lewis remains focused on what matters most to our customers: safe execution, dependable performance, and the confidence that their infrastructure is in capable hands.
