Meet

The Founders

Before founding Duet Design Group, Miranda and Devon were both making names for themselves in the Denver design community. Miranda owned her own design company and had been recognized by a number of builder's associations with awards for exceptional interior design. Meanwhile, Devon, a LEED Green associate and professional member of ASID, was working with a local architectural design firm.

The two crossed paths in 2011 in the carriage house behind Devon's childhood home. The rest is history. With a handful of personal connections and a passion for design, the duo teamed up and set out to create an interior design company that fulfilled the needs and wants of their clients, while simultaneously surpassing their expectations at every turn. Today, Devon and Miranda have a combined 30+ years of design experience and lead the dedicated, passionate and talented team of Duet. Their work has been recognized and featured in Luxe Magazine, Colorado Homes and Lifestyles, Reign Magazine, 5280 Home and Denver Life Magazine, among others.

Like most Colorado transplants, this mother of two left California nine years ago and never looked back. While admitting to missing the sand, her waterskis and In and Out Burger, Miranda couldn't think of a soccer field she'd rather be on than the ones in and around Denver. Winning the height battle by a long shot in our office, and by far the most experienced designer, Miranda is the go-to gal in our office for fashion inspiration and, most importantly, a complete recap of what happened that week on The Bachelor and The Bachelorette.

Mornings at Duet always begin with a Devon story, whether it be about her toddler, her family or an article she read in a business journal. Armed with a contagious sense of energy, passion and a Little Black Book that is anything but little (Devon knows EVERYONE in Denver), this mother of two keeps us on our toes. She found her love for design in the art studios of the University of Colorado and will admit to dreaming of one day returning to school....business school, that is. Multiple degrees run in the family.

Kate's claim to fame that she can outdrive most guys on the golf course is a definite plus for our offices' bragging rights. The lone "Cornhusker' of the group...yes, Kate hails from the beautiful state of Nebraska, this even-tempered and detail-oriented design associate worked for a high-end residential interior design firm in Aspen before heading down the mountain to Denver. She admits to being obsessed with wallcoverings, the color black and Kelly Wearstler. She craves mac & cheese, loves to Zumba and draws her inspiration from the pages of Vogue magazine.

Short, sweet, and southern, Sarah, Duet's Design Associate, packed her life into a Honda Civic and drove across country to pursue her passion for design. Inspired by the natural beauty of the Colorado landscape, (who isn't?) Sarah is ecstatic to have escaped Florida's heat and humidity. Sarah spends most of her free time acclimating herself to the altitude by pursuing adventure and exploring the great outdoors. (Say goodbye to sweat, Sarah!) Her spunk, desire to learn, and proclivity to risk taking make her a great addition to the Duet Team. And oh yeah, we love her tattoos.

Our first Illinois native to join the team, Karleen already had 14 years of design experience under her belt before joining us. She has both a business degree from CU Boulder and a degree in Interior Design from Harrington College of Design. She's our resident athlete being a certified yoga instructor and having completed a full Ironman distance triathlon. Her motivation for being so active is being able to eat all of the foods and drink all of the wine - two things that make her a natural fit at Duet. She has a fur baby with her husband and is always accessorized from head to toe - we're always looking forward to see which pair of shoes she has on next.

When we met Sarah Beth, we knew she would be a natural addition to the Duet team. A recent graduate from CSU, where she studied Interior Design with a minor in Sustainability, Sarah Beth is another team member from the South. She might be from Alabama, but she is a natural here in Colorado, spending her free time on a patio during happy hour, skiing, camping or getting down in the yogi lotus position. If she's not in Colorado, there's a safe bet she'll be soaking up the sun in her favorite place - Byron Bay, Australia.

With over 30 years of experience running a high-profile medical practice and years volunteering in the Denver community, Lezlie manages the finances, human resources and Foundation effortlessly. A mother of four with six grandchildren, Lezlie spends every spare moment with her family and friends, and never misses her weekly Canasta games and monthly mother-daughter book club.

There isn't a project we design that doesn't pass through the hands of Kimberly. With a degree in Business Administration and experience in construction management, Kimberly brings our designs to life, ensuring that every detail is ordered, delivered, inspected and installed. Armed with a quick smile and a "buck stops here" attitude, we owe much of Duet's success to her! A mother of two girls, this California native will tell you that she is a true Broncos fan, Pinterest obsessed, loves the game of golf and a self-proclaimed foodie and wine-lover (who isn't?)

Sarah is the first smile you see when you visit our office and the cheery voice you hear when you call. She is the scheduler, the gatekeeper, the record keeper and the gal who makes sure we are nourished throughout the day. A Colorado native, she recently got her degree at CSU and spends any of her extra time either finding her next favorite hike or spending time with her family. If it's football season, we know exactly where we'll find her - rooting for her Broncos!

Haleigh is our second member of the team to come all the way from Florida. She has a degree in interior design from Georgia Southern University and has worked in several different positions to give her the unique edge that helps her thrive as our Creative Coordinator. When she's not at work you can find her dreaming of the ocean, reading, doing yoga or making friends with every dog she meets.

Now, at age 11, Kiva spends his days sleeping on his dog bed, going for walks in the neighborhood and being the official greeter for all who visit our office. Whenever there are snacks around, Kiva is first in line and has been known to eat the goodies for client presentations prior to their arrival.
