The Firm

1989 – HAMILTONCLARK ORGANIZED IN HOUSTON, TX
HamiltonClark was founded in Houston with a clear mission: To provide personalized financial services to public and private companies that were often overlooked by larger Wall Street firms and regional investment banks. Our initial focus was on traditional oil and gas energy technologies.

1996 – ACQUIRED BY PRICE WATERHOUSE
In the summer of 1996 Price Waterhouse acquired the assets of our predecessor firm as PW sought to build a U.S. corporate finance practice. We became the Houston-based energy practice of PW Corporate Finance.

1999 – STARTED PWC’S CLEANTECH INVESTMENT BANKING GROUP
Price Waterhouse merged with Coopers & Lybrand to become PwC and we moved to Washington, DC.

2003 – RESTARTED HAMILTONCLARK
In 2003 we re-started HamiltonClark and re-acquired our original FINRA license. Our focus continued on cleantech and energy technologies.

2017 – HAMILTONCLARK EXPANDS
Our firm expanded to 17 Managing Directors in eight US cities. We continue to offer our clients the same commitment as we did when we began in 1989, stressing integrity, a “can do attitude” and professional Wall Street investment banking experience.

2022 – STARTED THE GOVERNMENT ADVISORY GROUP
Our Government Advisory Group was formed to advise companies that are seeking loan guarantees, government grants, and tax credits under various US government programs.

2025 – LAUNCHED GROWTH STRATEGY
We launched Growth Strategy as an opportunity to harness our firm’s expansive experience in advisory work and offer assistance to companies that are generally too early in their development to be able to afford a comprehensive investment banking engagement.
