Raised in the Midwest and shaped by architecture of both past and present, Keenan earned a B.F.A. in Interior Architecture and Design from the Milwaukee Institute of Art & Design, with additional architecture study at the University of Wisconsin–Milwaukee. Before founding One Room Atelier in Denver, he spent over a decade designing luxury residential kitchens and baths throughout the Rocky Mountain West that adds up to thousands of client consultations and full-cycle project delivery.

Before interiors, Keenan spent years on the other side of the wall — co-founding and curating DOUBLESPACE, and working as a fine-art handler and installer for Visions West Contemporary and Terry Dowd Inc. That gallery training is still how he looks at a room: composition, scale, negative space, and what a single object is doing in a space, before a single finish gets chosen. It’s a background almost no residential designer shares, and it’s why One Room Atelier reads more like a curated collection than a decorated room.

Architecture, context, and program act as a north star — guiding decisions from reflected ceiling plans and switching diagrams to the provenance of an antique cabinet. That residential foundation shapes everything, and it’s why One Room Atelier approaches small hospitality and commercial projects with the same rigor and collaboration usually reserved for private homes.

Since 2014, Keenan’s portfolio has spanned luxury residential and small hospitality work nationwide, with a particular affinity for luxury residential, turn-of-the-century architecture, and independent cafés, restaurants, and boutique hotels. Clients receive a clear, collaborative process and a hands-off, turn-key result — whether the project is a primary bath, a private residence, a thirty-seat dining room, or intimate chef table.
