Principal

Devon Tobin

Duet founder and principal Devon Tobin is an award-winning interior designer whose innate talents and distinctive eye for design have made her a highly sought-after design professional for more than 15 years. (Her warm spirit and hilarious sense of humor are a bonus.) A third-generation Coloradan, Devon has grown up alongside Denver, as it’s become a vibrant cultural city with a keener-than-ever taste for high style, and Devon and her team at Duet have helped expand Denverites’ palates with handsome luxury homes, vibrant commercial spaces, and distinctive multifamily residences.

Devon began dabbling in interior design as a child — fixing up her spaces so they felt good. She earned a bachelor of fine arts in painting from CU Boulder (Go Buffs!) and a bachelor of arts in interior design from the Art Institutes. She’ll tell you that creating holistic, gorgeous interiors is art mixed with a bit of science, a dose of alchemy, a whole lot of listening to clients, a good sprinkling of laughter, and some creative problem-solving. It’s a recipe for success: Devon’s work has been featured in Luxe, Design et al, 5280 Home, Colorado Homes & Lifestyles, and other notable publications.

Devon is a LEED Green Associate and an NCIDQ-licensed interior designer. She’s also a mom to two boys and wife to one amazing husband, and together they love to spend time skiing, hiking, and camping.

Sydney McManness - Interior Designer Open bio

Sydney McManness

Sydney has known since she was a child that she wanted to be an interior designer. She began her career at a design/build firm and then happily landed at Duet Design Group in 2019. (She went to an event at which principal Devon Tobin was speaking and asked for an interview!) Sydney loves every aspect of her work because Duet’s unique process enables the team to create a collaborative environment that makes the most of each member’s best skills. In her free time, Sydney loves to organize. (Yes, really.)

Sophia Shanley - Interior Designer Open bio

Sophia Shanley

Sophia has always satisfied her creative impulses with artistic work such as painting and drawing, but she got the urge to make a career switch during the pandemic, when she left her corporate sales job to pursue an interior design degree. She loves that the Duet team’s creativity and passion help shape clients’ everyday experience — of the design process and of the final product, their home. A Colorado native who relishes time outdoors, Sophia is also the oldest of four girls, and she loves being part of a big family.

Tracey Ranta - Creative Director Open bio

Tracey Ranta

A lifelong creative, Tracey’s love of studio art began at boarding school on the East Coast and led to a BFA in graphic design from the University of Denver. For more than 20 years, she’s worked in advertising, where her favorite projects involved developing residential design brands, so her job at Duet is a dream come true. Here, Tracey indulges her obsession with interior design, art, and architecture to promote a luxury brand that’s fueled by a team of passionate, organized, authentic women. Tracey loves a good live-music show, and she finds inspiration in nature and time with her daughter and two Sussex Spaniels.

Abbie Jahn - Project Coordinator Open bio

Abbie Jahn

With an undergraduate degree in chemistry and an MBA, Abbie worked for 25 years in the pharmaceutical and nutrition industry — which required her to move often. (She has lived in France, Thailand, China, Russia, and Japan!) She became a pro at transforming a new house into her own home and developed a love of interior design, which inspired her to go back to school, earn an interior design degree, and switch careers. Today, Abbie loves combining her business experience with her passion for beautiful interiors at Duet Design Group.

Melissa Thopsey - Staff Assistant - Duet Design Group Open bio

Melissa Thopsey

Melissa has long been drawn to beautiful things: She was an art history major in college and studied art restoration during a semester abroad in Florence. After graduation, she began an interior design program but didn’t finish, instead moving into an office management role at a consulting group on the East Coast, which she did for 15 years. Her role at Duet marries her administrative prowess with her fondness for working with creative women in a beautiful, thoughtful environment. When you meet Melissa at the Duet offices, ask her about her motorcycle license!

OFFICE MANAGER

Donna Wintzen Open bio

Donna Wintzen

Donna has 20 years’ experience in architectural, structural, civil, electrical, and interior design, in both residential and commercial environments. While she spent a nine-year stint in civil and electrical engineering, her first love is architecture and interior design. The thrill of taking initial ideas, carrying them through construction, and seeing the end results come to life never gets old. Nor does this tale from Donna’s childhood: When she was about 10 years old, Time magazine photographed her for being part of one of the youngest ballroom dancing couples in Denver. Alas, she never saw the photos—but she had a ball!
