What Kontogiannis & Associates does

Kontogiannis & Associates is a private, for-profit architecture, planning, and design firm headquartered at 400 South 5th Street, Suite 400, Columbus, Ohio. Founded in 1966, the firm employs 101-250 people and is licensed in 7 states with NCARB certification, supporting projects across the United States. The firm operates across three primary service sectors: Residential (including multi-family housing, mixed-use developments, custom homes, condominiums, and government-assisted and senior housing), Commercial (office and retail buildings), and Institutional (health care facilities including independent living, rehabilitation, nursing, and memory care units, plus religious architecture). Its differentiated offering is specialized healthcare architecture, particularly facilities serving seniors and Alzheimer's patients.

The firm's core technology is professional architectural services delivered across the full project lifecycle — schematic design, design development, building permit documentation, contractor bidding and negotiation, and construction administration — supported by in-house field representatives that inspect more than $30 million of new construction annually. The firm leverages productive working relationships with structural, mechanical, and civil engineering partners to deliver integrated architecture and engineering outcomes, and handles construction types ranging from wood frame to high-rise steel and pre-cast concrete structures.

The business model is project-based professional services: revenue is generated through quote-based fees for architectural and planning engagements, with no publicly disclosed pricing. Go-to-market is sales-led, driven by direct engagement with developers and project owners rather than channel partners. Customer segments span residential developers, healthcare operators, mixed-use developers, and commercial/institutional clients. Marketing is primarily website-driven (kontogiannis.com) supplemented by Facebook and X (Twitter) profiles. The firm has no disclosed parent company, subsidiaries, funding rounds, M&A activity, or leadership transitions.
