Bryan Sillery

Bryan Sillery is a Colorado native who grew up in the mountains west of Denver. He was fortunate enough to spend his 20’s in New Orleans and Atlanta, where he took to the friendly skies as a flight attendant before taking the plunge and trading his wings for an architectural scale. Bryan graduated Summa Cum Laude from Rocky Mountain College of Art + Design in August 2018. His passion for design started early, where the love of architecture and interiors drove his parents bonkers every time he rearranged the furniture growing up. Travel has been a major inspiration, and Bryan’s fun and unique style is a great match for Comstock Design.


Siera Stevens

Siera Stevens graduated Summa Cum Laude in 2018 with her BFA in Sustainable Interior Design from Rocky Mountain College of Art and Design (RMCAD).  She also has a BA in public relations.  After her first graduation, she was captured by the spirit of wanderlust and decided that the next step was to travel.  She left the country to teach English in China and spent the next three years traveling Asia.  After returning home, she knew that her passion for design was meant to be her career path and returned to school.  During her time at RMCAD she co-founded the student chapter of American Society of Interior Designers (ASID) and served as the student chapter president in 2017.  She was then appointed to the Colorado ASID professional board as the Student Representative to the Board for 2018.  Siera joined the Comstock Design family in July of 2018.
