REV. 2026 · SHO
For sixty-five years we have done one thing with singular devotion: listen to a family, draw in real time as they describe the life they imagine, and refine until the plan is exactly right.
Incorporated in Houston; becomes Harold H. Clothier & Associates in 1970 — behind homes in the city's most enduring neighborhoods.
A gifted designer who draws as clients speak. Made partner; the firm becomes Clothier/Sullivan and its reach spreads across the country.
Robert Henry (certified building designer, AIBD/NCBDC) and Bat Oggero (Texas A&M, Honor Society) join and shape the modern firm.
Trey Sullivan and Raina McChristian carry the practice forward — land planning, 3D visualization, the same devotion to the client's vision.
Tell us about the home you imagine. We'll draw it — the way we have for Houston since 1960.
