Hamilton Clark was originally organized in Houston, Texas as McKenna & Company in 1989. Throughout the early and mid-1990s we assisted numerous Southwest-based public and private companies that were overlooked by large Wall Street firms and by regional investment banking firms that had merged into larger financial institutions. Typically, our financing transactions are sourced from institutional private equity, venture capital or strategic corporate investors who were looking to extend their R&D and project activities by investing in promising new projects or technologies. We also assist private companies in selling their businesses, we help large companies divest of non-core operations and we have made principal investments in very early-stage companies. Based on the prior corporate and investment banking experience of our Managing Directors, we are sought out by companies that want Wall Street experience but without the cost or complexity of a Wall Street investment banking engagement.

In the summer of 1996 Price Waterhouse acquired the assets of McKenna & Company as PW sought to build a U.S. corporate finance practice. We became the Houston-based energy practice of PW Corporate Finance, and John McKenna became the head of PW's energy corporate finance practice in the U.S. During this period, our NASD member-firm, McKenna Securities Company, was acquired by Dominion Financial Partners, that focused its efforts on early stage, technology-based, venture capital investing.

In 2003 we organized Hamilton Clark and re-acquired the broker/dealer business from Dominion Financial Partners.

Today, our investment banking is focused exclusively on middle market public and private companies. We continue to offer our clients the same commitment as we did when we began in 1989, stressing integrity and professional Wall Street investment banking experience.


“Two American heroes, two great challenges, 200 years ago”

On July 11, 1804 America witnessed the death of its first Secretary of the Treasury. Considered America’s first investment banker, Alexander Hamilton convinced investors to finance the ultimate transaction, the birth of an infant country. Its value proposition was freedom and democracy for all. As a co-author of the Federalist Papers he died “believing he must meet his challenge on the field of honor.”

Less than two months earlier, another great American embarked on the ultimate due diligence assignment, “to reach the western ocean” and figure out what America actually bought in the Louisiana Purchase, its first big acquisition. Together with Meriwether Lewis, William Clark commanded “one of the most momentous journeys in American history.”

Challenging assignments ...experience counts.
