Your problems are our next inventions 

The challenges most people pass up, we see as opportunities to create unheard of innovations in the refrigeration industry. R.E. Lewis is proud of that reputation of providing remarkable service under what others see as ridiculous timelines.

Our team of project managers, engineers, and safety specialists work closely with each client to provide creative solutions to keep shutdown time and change orders to a minimum. Doing things correctly, safely, and effectively is the standard around here. In fact, we’re one of the few contractors with an on-staff safety specialist.

Family run.
Corporate savvy.

In 1957, in the rural town of Creston, Iowa, Robert Lewis and his son Earl, began R.E. Lewis Refrigeration. For more than 30 years, the family-owned business thrived by providing innovative industrial refrigeration to a wide range of clients. Specializing in ammonia refrigeration and mechanical piping, R.E. Lewis established a reputation of being harder working problem-solvers. Clients trusted them because they always honored their commitments to do the job right. On time, every time.

In the fall of 1991, Wayne Hanson purchased the corporation from Earl Lewis who had decided to retire. Recognizing R.E. Lewis’s solid reputation in the industry, Wayne decided to keep the name. Today, R.E. Lewis has expanded its corporate space and added an additional office in Dubuque, Iowa. Wayne continues to lead with the same principles of family values and hard work that transform new clients into long-lasting partners.

Meet Our Team

Wayne Hanson

CEO

Wayne is still crying over the Chiefs winning the Super Bowl. We can’t tell if they are tears of joy or from the cost of his ticket to the game. One thing that does get him emotional is his passion for ponies. The man has tons of high-end studs. Speaking of studs, did you know he has nine children? 

Janelle Buxton

Business Performance Integrator

As our Business Performance Integrator, Janelle has a knack for keeping people, projects, and priorities moving in the same direction. A proud sixth-generation farm kid and outdoor adventurer, she’s just as comfortable exploring riverbeds and remote trails as she is navigating KPIs and company strategy. When the leadership team starts heading in too many directions at once, Janelle is usually the one bringing everyone back into formation. Her favorite refrigerated item? A cold craft beer—which she considers an essential tool for post-project analysis.

Michelle Burnett

President | Business Development

Michelle is an underwater overachiever. This President | Business Development and SCUBA stud loves to take a deep dive into every opportunity and can handle serious pressure without coming up for air. Although a certified health coach, she’s completely crazy about ice cream. Whether above or below sea level, she always keeps her PSI in check — which, in her case, usually stands for Pints per Square Inch.

Trey Seward

Project Development Manager

With more than 30 years in industrial refrigeration, Trey has seen just about everything the industry can throw at him—and probably fixed most of it. After building and operating two ammonia refrigeration service companies, he now helps customers find practical solutions backed by decades of hands-on experience. When he’s not talking refrigeration, you’ll likely find him farming, entertaining his grandkids as the resident “monster,” or giving his wife one more reason to ask, “Really, Trey?”

Josh Lee

Project Development Manager

Don’t let Josh’s friendly demeanor fool you—he’s a full-blown refrigeration nerd, and he’s proud of it. As a RETA Authorized Instructor, CIRO-certified professional, and Project Development Manager, Josh has spent his career helping people understand and improve industrial refrigeration systems. If you ever wonder how serious he is about refrigeration, just know he has a Frick 9×9 compressor sitting in his front yard. Some people decorate with flowers; Josh decorates with compressors.

Holly De Hamer

CFO

Don’t let the petite, cute exterior fool you. Holly is a thrill-seeking daredevil. In her spare time, you might find her jumping out of a plane or screaming down the highway on her badass motorcycle. In the office, she gets her thrills by doing financial reports and spreadsheets in permanent marker.

Alishia Tucker

Senior Accounting Assistant

Alishia is in a tough spot. She loves the outdoors, but as a red head she fries easier than an egg in a skillet. Speaking of breakfast, her favorite food in the morning is leftover pizza. What? Not delicious bacon or buttery pancakes. Oh well. As long as she keeps collecting money for us the way she has been, she can eat whatever she wants. 

Stacey Buxton

HR/Safety Manager

Before joining R.E. Lewis, Stacey worked at a candy factory. She wasn’t Willy Wonka, but she made sure all of her Oompa Loompas were paid on time. And on her watch, nobody ever fell into the chocolate river. These days she has a sweet gig as our office manager and head of human resources. In her spare time, she enjoys golfing and baking delicious rhubarb pies that’ll put you in a world of pure imagination. 

Jason Sanders

VP of Service

Jason brings 15 years of expertise and a relentless drive to exceed customer expectations. A two-time Iraq veteran and former NASCAR tire changer, Jason thrives under pressure, ensuring every service call is as efficient and precise as a pit stop. Focused, goal-oriented, and fueled by a passion for service, Jason is dedicated to keeping customers cool—no matter the challenge.

Matt Schultz

Director of Engineering & Design

Matt has been working in the construction industry for so long you’ll find his initials on the base of the Great Pyramid of Giza. These days, he’s making his mark constructing industrial refrigeration systems for some of our biggest clients. He’s still getting used to signing contracts without a chisel.

Lyn C. Mangrich

Engineering Consultant

Lyn, our engineering consultant, has had a pretty cool career. Literally, with 35 years in the refrigeration industry a lot of his life has been dealing with ice. He loves to chill so much he even builds curling sheets, ice sculptures, ice fishing, you name it – if it freezes it pleases him. He even dressed up as Elsa the Snow Queen for Halloween. For some reason, he just can’t let it go, let it go.

Roberta Cantu

Project Engineer

Roberta may be an engineer by title, but she’s also a bilingual Houston Astros superfan who can just as easily optimize a process as she can spot a hidden gem at a thrift store. When she’s not traveling, running, or watching movies, she’s probably dreaming about her favorite refrigerated combo: an ice-cold lemonade and a ballpark hot dog.

Nick Walsh

Project Engineer

Nick brings a practical, get-it-done approach to every project. Before joining the refrigeration industry, he served as a Captain in the U.S. Army Field Artillery, where precision, leadership, and operating equipment that goes boom were all part of the job. These days, when he’s not solving project challenges, you’ll likely find him farming, working on his truck, or building another chicken coop for his wife. His favorite refrigerated item is a Dairy Queen Dilly Bar—because even Army captains know some problems are best solved with ice cream.

David Marroquin

BIM/CAD Manager

Meet David Marroquin, our BIM/CAD Manager who’s climbed the ammonia refrigeration ladder with flair! With over seven years of experience, he’s gone from project assistant to modeling and coordination expert. A proud Spanish speaker, David enjoys bicycle riding and 3D printing in his spare time. And when it comes to chilled treats, nothing beats ice cream! Need a precise model or a scoop of fun? David’s your guy!

Seth Hanson

Estimation Manager

Seth is a die-hard Chiefs fan and woodworker. In fact, he brought his own hand-carved tomahawk to game to partake in Arrowhead’s famous tomahawk chop chant. After being deemed a security risk, a brief tussle ensued and he was politely escorted out.

John Gravlin

Construction Manager

With 10 years at R.E. Lewis and a background in agriculture, John brings solid experience and a steady hand to every project. He’s also a hot air balloon event director, woodworking enthusiast, and proud dad of two — proving he’s comfortable managing both high-pressure systems and high-energy toddlers. His favorite way to cool down? A tall peach tea, a scoop of ice cream, and a little fresh air.

Gage Skarda

Project Manager

Gage joins R.E. Lewis Refrigeration with 2.5 years of ammonia refrigeration experience and a lifetime of hard work on his family farm raising Angus cattle. When he’s not helping projects run smoothly, you can find him cruising on his motorcycle, hunting, or keeping the world stocked with his favorite refrigerated items: bacon and beer.

Dan McNamer

Project Manager

Dan has been in the piping trades for nearly 20 years, and for the past 8 years, he’s been chilling with us. As our project manager, Dan takes charge of everything, including prepping materials, labor costs, bidding, scheduling, and keeping everything on schedule. He enjoys time with his family, coaching, and teaching. When he’s not wrestling with timelines and budgets, he’s often grappling opponents into submission in Brazilian Jujitsu.

Juanita McCarthy

Operations Coordinator

Juanita McCarthy, our HR/construction whiz! She’s the orchestrator of our industrial refrigeration symphony, having mastered the art of inventory at a candy factory for a sweet 25 years. Off-duty, Juanita’s a thrift store ninja and camping aficionado. You’ll often catch her chilling on her revamped patio, sipping cold drinks with her two Labradors by her side. Whether she’s crunching numbers or chilling out, Juanita brings a frosty freshness to our team at R.E. Lewis. Cheers to that!
