Our headquarters is based in a row house in the Adams Morgan neighborhood of Washington, D.C. We also keep offices in Northern Virginia and in Montgomery County, Maryland. Most private investigations can be initiated over the phone or via email, but we are generally willing to meet with new law firm clients at their locations. While walk-ins are discouraged, we can usually meet clients in our D.C. office on the same day and in the other locations within 24 hours. Please contact us about hiring our firm for an investigation.

Dinolt (U.K.) Ltd., our sister firm in London, can be reached through our D.C. office.
