Oppenheimer Investigations Group LLP launched in 2021, as a new partnership growing out of the Law Offices of Amy Oppenheimer, which opened 25 years before. Partners Amy Oppenheimer, Vida Thomas, Christina (Tina) Ro-Connolly, Zaneta Seidel, and Alezah Trigueros, joined by all the attorneys and staff at the Law Offices of Amy Oppenheimer, came together to lead the new firm with an eye toward the future of this growing industry.

As of August 2024, the firm has 22 attorney investigators.

We operate as virtual firm throughout California. Our attorneys and staff are spread across the state, in areas including the San Francisco Bay Area, Los Angeles, Santa Barbara, San Diego and Sacramento.
