She represents clients in reviews, interviews and investigations by the SEC, the Department of Justice, state securities and insurance regulators, and self-regulatory bodies, and also represents them in any resulting disciplinary hearings, trials and appeals.

Employment Litigation

Sandy also has a robust single-plaintiff employment claims defense practice, and frequently investigates employee complaints of discrimination, harassment and retaliation as well as whistleblower complaints. She represents corporate clients in federal courts across the country and before the Equal Employment Opportunity Commission (EEOC) as well as before state divisions and commissions of human rights.
