With over 30 years of collective expertise in residential and commercial applications, the team continues to challenge each other to generate designs that delight. The principals, Devon Tobin and Miranda Cullen, have fine-tuned a unique and seamless process that assimilates their client’s inspirations, taste and style to create designs that are unique and equally functional.

Devon Tobin is a creative, multi-faceted entrepreneur and interior designer who has the capacity to take the fear out of change while providing her clients with the vision to imagine the possibilities. Many have said Devon’s personality is contagious with the unique ability to excite and inspire. She designs with function before form, understanding how spaces will be used prior to design. Even before professional training, Devon could create environments that attracted those around her. A fourth generation Colorado native, Devon graduated from both University of Colorado Boulder & Art Institute of Colorado and strives to be an advocate for the Tiny House Nation.

Miranda Cullen is a strategic entrepreneur with an eye for creativity and design perfection, who continuously excels in every aspect of interior design. From the onset of her career, Cullen took the model home industry by storm, mentoring and managing successful design teams through thoughtful leadership. With well over 800 homes in her portfolio, Miranda has been recognized by her peers with multiple awards and accolades. A strong personal following of clients from California to Colorado repeatedly seek out Cullen’s professional expertise. Miranda views every project as a unique puzzle, challenging her to create designs that surpass client’s expectations.

Duet’s expansive and diverse portfolio has not gone unnoticed by the press. Several projects have been featured in LUXE magazine, 5280 Home, Denver Life Home + Design, Houzz and nationally recognized by the Home Builders Association.
Fulfilling a lifetime dream of giving back, Cullen & Tobin recently launched a foundation extending their design services through charitable activities.
