What DMHA does
DMHA is a full-service architecture and interior design firm headquartered in Santa Barbara, California, founded by Michael Holliday circa 1989 (originally as Holliday & Associates) and reorganized as a four-principal partnership in 2012 with the addition of Ed deVicente and Ryan Mills, followed by a fourth principal in 2017. The firm operates with a small core team that has expanded by approximately 300% over the past decade and serves clients across California's Central Coast, including Santa Barbara, Montecito, Goleta, Carpinteria, Buellton, Los Olivos, Isla Vista, and Ventura. Service offerings span programming and predesign, site master planning, building and feasibility analyses, architectural design, interior design, construction administration, and sustainability/LEED consulting, organized around four primary verticals: residential, commercial, mixed-use/multifamily, and hospitality, with a community-focused placemaking practice layered on top.
DMHA's core technical capabilities center on sustainable and resilient design, including Passive House consulting (Ed deVicente is a Certified Passive House Consultant since 2010), LEED advisory with over 25 years of sustainable design practice, net-zero energy design, biophilic design, and fire-resilient/wildfire-resistant architecture. The firm has conducted applied research with Lawrence Berkeley Labs and Southern California Edison on phase change drywall and energy monitoring dashboards, deployed in The Loop student housing project. Notable projects include the 155,000 SF Direct Relief Headquarters (a multi-award-winning sustainable facility), Mattei's Tavern Resort (67-key Auberge property in Los Olivos), The Goodland Hotel (158-room Kimpton renovation), The Loop UCSB student housing, the Santa Barbara Humane campus, and numerous high-end residential estates and multifamily developments.
The business model is professional services-based, with revenue earned through project-based architecture and interior design fees quoted per engagement based on scope, complexity, and square footage. Multi-year contracts run from programming through construction administration. Go-to-market is principal-led and relationship-driven, supported by community involvement, AIA participation, awards-based visibility, and a portfolio website rather than paid marketing. DMHA is privately held, has no external investors or parent company, and does not publicly disclose revenue or financial statements. Over its history, the firm has managed more than $500 million in architectural projects and accumulated an extensive awards portfolio from AIA, USGBC, the California Governor's Office, and regional industry bodies.
