About Njeri
Biography
Njeri London co-founded L and L Law Group, PLLC alongside Reggie London to deliver attentive criminal defense across North Texas. Her practice is rooted in disciplined preparation, meticulous discovery review, and consistent client communication, supported by a defined in-house trial team rather than outsourced contract attorneys — the components that turn a defense file into a defensible record.
Njeri represents clients in state matters across Collin, Denton, Dallas, and Tarrant counties, with select federal representation. She handles the full criminal docket from misdemeanor traffic-stop charges through felony indictments, drug offenses, family violence, theft, assault, sex offenses, and white-collar matters.
Her courtroom work emphasizes structured cross-examination, evidentiary motion practice under Texas Code of Criminal Procedure article 38.23 and Federal Rule of Evidence 702, and clear, calibrated jury argument. Outside of trial, she focuses on negotiating pretrial dispositions that protect clients’ employment, immigration status, and professional licensure.
Njeri is a dedicated criminal defense attorney serving Collin, Dallas, Denton, Tarrant, Rockwall, Kaufman, Ellis, Johnson, and Hunt Counties. She provides strategic, compassionate representation in criminal, DUI, traffic, juvenile, and assault cases.
