TSHD Architects

What TSHD Architects does

TSHD Architects (legally Tanner, Stone, Holsinger, & Donges) is a full-service architecture firm headquartered in Portsmouth, Ohio, with continuous operating history traceable to DeVoss & Donaldson Architects founded in 1916. The firm is structured as a private partnership led by principal architects Kirk Donges (CEO), David Stone (CAO), and Mark Holsinger, supported by a small technical and administrative staff of approximately 11-50 employees. Its service portfolio spans architectural design, master planning, sustainable design, interior design, graphic design, and project management/construction oversight, with design work executed through standard CADD pipelines rather than proprietary technology platforms.

The firm operates a relationship-driven, project-based professional services model across multiple verticals. Its two primary verticals are K-12 education — through which it has designed more than $300 million in buildings via the Ohio School Facilities Commission program across more than two dozen school districts since 1998, including athletic facilities, stadiums, and learning environments — and healthcare, with multi-project engagements for King's Daughters Medical Center, Southern Ohio Medical Center, and Adena Health Center. Secondary verticals include financial institutions (Desco Federal Credit Union, Atomic Employees Credit Union), government/civic (Scioto County Job & Family Services, Portsmouth Fire Department), commercial/retail, and religious/community buildings.

Revenue is generated through quote-based project fees that vary by scope, complexity, and client requirements; pricing is not publicly disclosed. The firm is licensed in Ohio, Kentucky, and West Virginia, with project work concentrated within an approximate 100-mile radius of Portsmouth across the tri-state region. Customer acquisition relies on direct enterprise engagement, an active website and social media presence (Instagram, Facebook), community-event sponsorship including Building Doctor clinics with the Ohio Historic Preservation Office, and demonstration through an extensive multi-sector portfolio spanning civic, commercial, education, financial, healthcare, historical, housing, religious, and retail categories. TSHD is an active member of the U.S. Green Building Council.
