HCO, Inc. was established by Henry C. Onochie, AIA, NCARB, in 1989 in Indianapolis, originally as a single-man firm operating out of a private residence. The firm was incorporated by 1990.

At its startup, Mr. Onochie discovered that most lending institutions were unwilling to lend money to a minority company with such a short period of establishment. This and other adversities did not deter Mr. Onochie from persevering. Rather, it fueled his desire for determination and success.

HCO, Inc.’s work began with small-scale, private, and government projects, and has since evolved into a broad spectrum of private and public projects, ranging in size from $2 million, to over $55 million dollars in project cost.

Today, the firm is comprised of over twenty-five professionals who reflect HCO’s commitment to excellence in quality design and client service. Each of these individuals contributes a vital knowledge of architecture, design, and engineering, and through spirited collaboration, delivers persistent attention to quality and detail to each project.
