What DPH Architecture, LLC does

DPH Architecture, LLC is a privately held, full-service architectural design firm headquartered in Canfield, Ohio. The firm was originally established in 1983 by Thomas Keller and was acquired and rebranded by David P. Harris Jr. in 2010. The firm operates as a traditional professional services practice with no proprietary technology platform, relying on industry-standard design tools, CAD drafting, and conventional architectural methodologies to deliver projects from preliminary design through construction administration. Its core offering is comprehensive architectural design services spanning eleven vertical categories: Corporate, Educational, Financial, Healthcare, Hospitality, Industrial, Municipal, Religious, Residential, Retail, and Accessibility.

The firm operates on a project-based professional services revenue model, with fees custom-quoted based on project scope, complexity, and requirements. It serves clients across multiple U.S. states — enabled by the principal architect's licensure in six states — with named engagements including First National Bank (multi-branch work across Ohio, Pennsylvania, Maryland, Virginia, North Carolina, and South Carolina), Home2 Suites by Hilton (Austintown and Canton), Farmers National Bank, Sharon Tube Company, Wheatland Tube, Mike Pruitt Honda, America Makes, BC3, and various healthcare, municipal, religious, and industrial clients. A specialty Accessibility Evaluations practice has evaluated over 300 properties and designed solutions for over 150. The principal personally oversees all projects from initial planning through building occupancy, providing single-point-of-responsibility accountability.

The firm is a tightly held owner-operated business led by Principal Architect/Owner David P. Harris Jr., supported by a team of approximately 8-9 staff including licensed architects, project managers, architectural designers, an intern architect, an office administrator, and seasonal interns. It maintains a strategic partnership with Steel Rooted Custom Designs for custom furniture offerings. Distribution is entirely direct via principal-led client engagement and repeat business; there are no intermediaries, resellers, or external investors. Marketing is limited to a portfolio-style website and a Facebook page, with growth primarily driven by project portfolio visibility and professional network referrals.
