Sullivan Henry Oggero & Associates

What Sullivan Henry Oggero & Associates does

Sullivan, Henry, Oggero & Associates, Inc. is a privately held, founder/partner-owned residential design firm incorporated in Houston, Texas in 1960 (originally as Dwayne J. Meyer and Associates). The firm provides custom home design services spanning preliminary sketches through complete construction documents, including site planning, floor plans, elevations, engineering coordination, and permit packages, with complementary 3D animation and rendering for visualization. Design projects range across homes priced from $350,000 to $20 million, serving high-net-worth individuals (including professional athletes, political figures, entertainers, and Fortune 500 leaders), general custom home buyers in the greater Houston area and across multiple U.S. states, and home builders/developers requiring multi-unit or single-family design packages.

The firm's underlying technology is Computer-Aided Drafting (CAD) combined with 3D modeling and animation, used to support a collaborative, real-time design process in which partners work with clients during consultations to sketch and iterate designs. The team of over 25 professionals is led by four named partners (Robert Henry as COO, Bat Oggero as President, Trey Sullivan as VP Operations, and John Sullivan as founder), plus a junior partner, with credentials spanning TIBD, AIBD, NCBDC certifications and Texas A&M Architectural Honor Society membership.

Revenue is generated through two primary streams: (1) professional services fees for custom residential design, billed on a tailored, project-by-project basis with options for design-package-only or full-service engagement through construction documents, and (2) construction license fees from selling building plans and licensing rights, required by copyright law for repeat builds from the same design. The go-to-market is sales-led and almost exclusively referral-driven, with no external marketing investment beyond a portfolio website and participation in showcase events (Street of Dreams, Parade of Homes, ASID Home Shows). The firm has no disclosed external equity, no funding rounds, no parent company, and no subsidiaries.
