Driehaus Capital Management LLC is committed to aggressive growth investing. We consistently focus on companies that we believe have strong growth prospects, and seek to take maximum advantage of opportunities that arise in a dynamic market environment. Although our process involves much discipline, we believe it is, by design, flexible enough to react to changing market conditions. We do not mimic any external index or benchmark, nor are we restricted by strict price/earnings multiple constraints. We do, however, believe that things in motion tend to stay in motion , so we place our primary focus on the growth and quality of earnings.
