This philosophy, along with our commitment to design-build excellence, has evolved into a process that is clear, direct, and practical.

We’ve turned hundreds of dreams into the reality of new living spaces. Let us show you how fun, affordable, and rewarding the design-build process can be.

Josh McDermott


After graduating from the University of Missouri-Columbia, College of Business, Josh worked for a time in pharmaceutical sales. But construction has always been a part of who he is. Even before he knew what remodeling was, he could often be found accompanying his dad for truck rides to jobsites and lumberyards. At 15, his father introduced him to the remodeling “business,” and since that time Josh has enjoyed watching how transforming someone’s home or business also helps transform their lives.

In the fall of 2015, his father handed over the reins of the company to his son. For Josh, it’s always been about relationships. As J.T. McDermott’s 2nd generation owner, he believes nothing matters more than the enduring friendships that are built with the homeowners he serves. “If I can help both our clients grow and the team grow, everything else will take care of itself.”

Besides his university degree, Josh is also a Certified Graduate Remodeler. A deep belief in giving back runs through Josh’s personal and business life. He serves as a business mentor to community high school students, and supports a number of philanthropic causes including animal welfare, arts and culture, domestic violence, economic empowerment, education, environment, and health.

When he isn’t involved in running the business, Josh loves to spend a lot of time with family and friends cooking. He also enjoys traveling, boating and sailing on Lake of the Ozarks, and running on the weekends with his wife, Victoria – they both do a few half-marathons a year. But today, nothing brings more joy to Josh and his wife’s life than the time they get to spend with their young daughter, Lyla.

Diane Mueller

Accounting and Finance Manager

When Diane isn’t swimming in paperwork as our accounting and finance manager, she’s training at an O’Fallon, IL pool for the June 2017 Senior Olympics. Diane took up swimming in 2013 and, in her first ever competition in 2016, qualified for eight races, including the 100-meter freestyle, backstroke, breast-stroke and butterfly; three 50 meter events; and the 100-meter individual medley.

A CPA, Diane joined McDermott Remodeling in 2015. She finds analyzing financial statements, what she calls the heartbeat of the company, as the most interesting part of her job. She is a Magna cum laude graduate of McKendree College and has worked for Anheuser-Busch/Inbev, Grossman Iron and Steel, and Ralcorp. She and her husband, Mike, have three grown children.

Ron Mifflin


Ron laughs whenever he says his job is to be the bearer of the cold hard facts for remodeling projects. Ron is the resident numbers cruncher, helping clients meet their budget and get the remodel they’ve dreamed of. He considers himself the “man behind the curtain” who’s always looking out for the best interests of the client.

Both his father and grandfather were carpenters and Ron worked for his dad during high school summer breaks. His career includes graduating from the Carpenters Apprenticeship Program and working on several high profile construction projects in the St. Louis area. Ron and his wife, Kary, have four children. He enjoys golf, fishing, hunting, and attending concerts.

Megan Gerdes

Interior Designer

Megan’s interest in interior design was sparked at a young age. As a four-year old, she loved going to restaurants with her parents and looking at how the restrooms were decorated. The interest blossomed and after high school she went on to study interior design at Chicago’s Illinois Institute of Art. Her passion for design extends beyond her workplace. In her free time, Megan enjoys all types of crafts, including knitting, crocheting, and rehabbing/reupholstering furniture.

For Megan, the most interesting aspect of her job is space planning. For her, an empty basement or a soon-to-be-remodeled kitchen is a blank canvas, just waiting for her to fill it with beauty and functionality.

Brittany Allen

Interior Designer

Brittany’s fascination with interior design was sparked by DIY television programs. “That would be fun to do,” she remembers thinking. When she learned that people were actually paid for such work, her career choice was decided. Brittany received her interior design degree in 2010 and recently earned her kitchen and bathroom certifications. She sees her job as much more than just picking out pretty colors and materials – it also involves exact measurements, plenty of planning, and determining how to have a space accurately reflect the lifestyle of its occupants.

Brittany and her husband, David, welcomed a son in 2016 and tending to his needs leaves her little free time. Avid foodies, when the couple does go out on their own, they love exploring new area restaurants.

Dave Dermody

Lead Craftsman

Dave Dermody knew at an early age that he wanted to be carpenter. Inspired by his father who was a millwright, he took on his first major project when he was 16 years old by building a shed for his aunt that still stands today.

Dave joined Foppe-McDermott Remodeling-- the precursor to today’s company-- 29 years ago at a time when he was working as a maintenance man at an apartment complex. Those skills have come full circle as, in addition to his carpentry work, Dave heads “Service by McDermott,” which provides routine house maintenance for a host of clients.

Dave is thankful that the skills he has acquired from this position have afforded him the ability to give back to his community. Some of his favorite projects include building dugouts at the Wolf Branch Middle School softball fields and volunteering at the construction of Swansea Kingdom playground. He loves to help friends and family with remodeling projects, and he has enjoyed coaching numerous youth sports teams, such as soccer, softball, and basketball.

Dave and his wife Robin have three daughters. Lauren will be attending University of Missouri- St. Louis to earn her doctorate in optometry, Amanda will be attending Gulf Coast College to play competitive softball, and Allison will begin high school at Belleville East.

Rob Ledee

Production Manager

Except for a four-year stint in the U.S. Marine Corps, Rob’s been a carpenter since high school graduation. His high school shop teacher, whose father owned Gossert Construction in Millstadt, noticed Rob’s knack for the trade and recruited Rob for a job with the company. For a time, Rob worked with an area realtor to help prepare houses to be flipped, often gutting a home and putting it back together before it went back on the market. Rob’s exceptional talent is in trim work, a meticulous process that gives a room its “wow factor.” It’s a beautiful finishing detail that Rob says cannot be rushed.

Kenny Jamison

Lead Carpenter

It’s no small feat to become one of our lead carpenters in a little over a month. Kenny takes pride in the work we do at McDermott Remodeling, and it shows. Kenny loves it when a home improvement project comes together more than Hannibal Smith enjoys concocting daring escape plans. Kenny’s solutions are also a bit more practical, which is why he’s an essential part of our A-Team. He enjoys making our customers happy with their homes and feels a profound sense of accomplishment when it’s finished. After all, the house didn’t remodel itself! In his personal life, Kenny prioritizes spending time with his fiance, kids, and the rest of his family. It would be a little weird if he didn’t.

Barbara Smith

Client Services Coordinator

Barbara joined our team as a Client Services Coordinator in the middle of August. McDermott Remodeling is a family-focused design and build company. We improve the lives of our customers with the work that we do, which is what Barbara helps coordinate. Barbara does her part to make our team even more friendly and helpful by adding her own super friendly and super helpful character to the mix. As part of her job, Barbara helps put customers at ease and makes sure they know their home is in good hands. Taking her great personality with her outside of work, Barbara loves spending time with her family and friends, especially while camping, playing board games, visiting wineries, and checking out new places. She bolsters the sense of caring that imbues our company and helps our customers feel like they’re also part of the McDermott Remodeling family.

The best is expensive. I got the best service and quality of work. Always remember that the best does not cost, it pays.
David B.
