Our philosophy is simple: to build a better way. And that means using better methods. Our Whole Systems Approach to construction reduces our impact on the environment while helping homeowners minimize their energy consumption.

We like to think of it as building a better way of life for homeowners—building long-lasting and healthy homes that require less energy and resources to operate.

It also means that our processes are centered on building strong, collaborative relationships. We know that our success depends on good communication, honesty, and high-caliber customer service.

And building a better way means clearing the path for change in the construction industry.

Our goal is to promote sustainable building practices and help educate the public about the importance of green construction.

Sustainability is important to us because it is critical to the health of our planet and the quality of your project.

But above all, we build green because it’s the right thing to do, just like ensuring quality customer service, promoting collaboration, or improving communication and transparency. It’s about building a better way.

So from your first interactions with us to the final moments of your project, we hope to deliver a distinctly positive experience—one that matches the quality and the longevity of your home.

Ethan Collier PRESIDENT | CEO
view bio

Since starting Collier Construction in 2001, Ethan has set the highest priority on customer needs and building a unique and quality product that both he and the customer love.

“For us, it’s not about building a product as much as it is about customer service. I think that’s unusual in construction, but for us it’s about looking at how we can meet the need of each client. Our commitment to customer service really sets us apart.”

Ethan has a very hands-on approach to beginning any project his company takes on. He is the first person to speak with each potential customer, and it’s his desire to make sure that Collier Construction is a good fit for all potential projects. Then he works side-by-side with his staff to ensure they have what they need in order to get the job done correctly.

While Collier Construction puts its focus on customer service, the company remains dedicated to the highest quality of construction techniques and getting the job done right. In 2009 Collier received the President’s Award from the Home Builders Association of Southeast Tennessee and in 2010 the President’s Award from the Home Builders Association of Greater Chattanooga. Collier was named 2011 Small Business of the Year by the Chattanooga Area Chamber of Commerce and also received the Torch Award from the Better Business Bureau in 2013.

Ethan is a LEED® accredited professional builder and is licensed to build in Tennessee and Georgia. He has previously been recognized as Entrepreneur of the Year by the Young Professional Association of Chattanooga and actively engages issues of economic development and environmental stewardship in our community. He currently serves on the board of directors for the Home Builders Association of Southeast Tennessee and Habitat for Humanity of Greater Chattanooga. He is a member of the Construction Management Advisory Committee for ITT Technical Institute and also serves on the United States Green Building Council.

Rick Roberts CFO

Rick’s list of qualifications is as long as it is impressive. On top of spending years in the construction industry getting his hands dirty with framing and roofing, he most recently served a ten-year stint as the CFO for Habitat for Humanity. Rick decided to join the Collier Construction team based on Ethan’s reputation of integrity and leadership.

“I know enough about Ethan to know that he is not in this for the dollar. It’s the minutia. Ethan is constantly looking ahead in the consumer’s life. Way down the line they will be glad they went with a Collier home. He’s made a company centered around anticipating the needs of the customer 10 years from now.”

Experience in the field and knowing the language of the industry are only part of Rick’s success as a financial officer. Being a father of 8, has allowed him to bring an invaluable trait of flexibility to Collier Construction.

“You got be flexible with a family like mine… I am accustomed to different people from all different parts of an organization needing things from me simultaneously. I’ve got to be able to able to shift gears at any moment to deal with a staff issue, POS systems, construction departments, you name it. It’s about understanding and meeting the needs of your team (or family).”

Looking forward, Rick’s major goal is to bring Collier’s concept of “thoughtful living” to the realm of accounting. If Collier Construction’s building endeavors are a delicate balance between awareness of present needs and a responsible understanding of the future, then Rick plans to operate their finances in a similarly thoughtful method.

Daniel Rakes Warranty Manager
view bio

Daniel has always known he would work in construction. Back home in Delaware, Daniel got his start cleaning up construction job sites while still in high school. It wasn’t long before he was working with framing crews and picking up the trade as fast as his foreman could task him. Fast forward to university and he’s studying architectural engineering and construction management. In a fortunate turn for Collier Construction, Daniel eventually decided to move south to be near his siblings living in Nashville.

As a warranty manager, Daniel has expanded his knowledge and skill set. You are likely to find him speaking with and listening to Collier home owners:

”One thing about me is I am not necessarily a huge talker. I am a good listener. People feel heard around me. I want to hear everything a person has to say… Sure, my hands-on experience from the field helps me understand exactly what a homeowner needs, but it’s listening carefully that makes me good at what I do.”

Daniel and his work ethic represent Collier Construction’s ongoing commitment to lasting relationships with homeowners. When Daniel is not addressing client needs or scheduling subcontractors he’s spending time with his lovely wife, Gianna. Daniel and Gianna spend their weekends giving back to the community via their church’s youth program.

Ernie Freistat Project Superintendent
view bio

Ernie Freistat got his introduction to construction early in life as a day laborer on construction sites in his teens. At the time, he worked his way up the ranks before making a switch away from his family's Florida-based construction company to try his hand in sales and marketing.

"But I always enjoyed the challenge of it," he says of construction work. "It's rewarding to put a job together and watch it grow."

Ernie eventually found his way to Chattanooga (and back into the construction field) through what was supposed to be a temporary visit to the Scenic City. Now, years later, he proudly calls it home.

"I was only ever going to stay for a year," he laughs. "I was just looking for something different to do with my life."

And in Chattanooga, Ernie found it, both in terms of a successful career in an industry he loves and a woman to share it with: the love of his life, Noelle.

"What sticks out to me at Collier is that we are all team players. It's such a great atmosphere to be in and be a part of."


Harrison Bostwick Project Superintendent
view bio

Harrison Bostwick is first and foremost a problem solver.

As a project superintendent, he brings his extensive background knowledge from residential and commercial construction to the table. But even before that, he was always a builder at heart; he and his father built the house he grew up in.

"I just always liked building," he says. "I remember I was on a flight to Florida years ago in college, talking to someone about how I didn't know what I wanted to do when I realized it."

After making the jump from architecture to business, then finance and marketing, Harrison rediscovered the passion he'd always had for building and problem-solving. Since then, he's never looked back.

Now, when he's not overseeing the progress of Collier projects, you can find him working on his fiance Taylor's family farm or restoring old cars with his dad.

"If I'm not with my fiance and our dogs, you can find me in the shop my dad and I have," he says. "It's another outlet for building and problem-solving."


Jon Arnold Project Superintendent
view bio

New to Chattanooga, Jon Arnold is originally from Whidbey Island, Washington. He has quickly fallen in love with Chattanooga’s accessible outdoors scene but more so loves the copious family-friendly activities. On weekends you are likely to find Jon, his wife, daughter, and son exploring the city.

Like many of Collier Construction’s employees, Jons relationship with building came at a very young age. Growing up, his dad was a general contractor, and Jon started working on construction sites from age 12. He learned straight from his father how to build a house from the ground up, everything from framing to finishing. He would later expand his practical knowledge of building by studying business management with focus on supply chain management at Central Washington University.
After a years as a mechanical contractor on large commercial projects Jon finds the dynamism of Collier Construction very appealing. Rather than being pigeon-holed into a single facet of a project, Jon now oversees the entire scope of a build. It’s his high degree of organization and attention to detail that make him uniquely qualified to manage community projects like Collier’s Reside North.
Working at Collier is great because you get to know everything in more detail. You get to know everyone in the company individually, but at the same time you get to see a project all the way through. You get to leave your fingerprint on every part. It’s awesome to see huge projects come together quickly and efficiently.


Nate Holland On-Site Support
view bio

When Nate Holland was a kid, he was convinced he wanted to be a stuntman — or a crocodile hunter like the late Steve Irwin.

And while he opted for a life surrounded by people in Chattanooga instead of wild animals in the Australian outback, Nathan loves what he does.

He began his experience at Collier as a laborer and quickly moved up the ranks to manager since he moved to town from Lawrenceburg, Tennessee a couple of years ago.

When he's not hiring and scheduling laborers or anticipating any other needs at construction sites, Nathan is most often at his church, Calvary Chapel, volunteering or fellowshipping with others.

"What I love most is the people," he says. "I'm a people person and that makes it really easy to come to work and do my best every day."



Patrick Dugan Project Superintendent
view bio

Patrick Dugan discovered his love of real estate from a young age. But before his penchant for learning how to renovate his North Shore home led him to construction and a career at Collier, Patrick previously worked as a home inspector, house flipper, and a wine rep.

"I've always been into real estate," he says. "From a young age, I was fixing houses up. ... Once it's in your blood it's hard to get out."

Once the Chattanooga native made the leap from the Nashville-based wine company to construction books on how to fix the crown moulding in his home himself, he never looked back. Now, with close to 20 years of experience, Patrick prides himself on being well rounded and versatile — both in the industry and in his personal life.

When he's not managing projects and ensuring operations are running smoothly, you can find Patrick playing mandolin for his bluegrass band, Broke Down Hounds, or cheering on his daughter in her varsity soccer matches.

"She's really good — and I'm not just saying that because I'm her dad!"

“I just wanted to take the opportunity to thank you personally for the SMMHS press box that Collier built/donated. As an announcer, the security provided allows us to safely store necessary PA equipment making each week's setup incredibly easier and more efficient. And it allows us to concentrate on the tasks at hand before, during and after the game as well as at halftime. Of course, it affords us a considerable amount of comfort as well with the outlets (fans/heater), lights and escape from the elements. The fact that you were able to do it "green" AND donated the time and materials is simply amazing. Thank you again for what Collier continues to do for our community!”
Dave Wagner
“Our offices look just great and I am very thankful to your team for getting the project done on time for our meetings today. All of the subs kept clean spaces, were friendly, and quiet – so it worked out just awesome. ”
