About Guerrero Investigations
A licensed Texas PI firm built on law enforcement experience and clinical expertise — two qualifications most firms simply don't have.
Where Law Enforcement Meets Clinical Expertise
Guerrero Investigations was founded on a simple belief: the best investigations draw on more than surveillance skills. Our CEO, Billy Guerrero III, retired as a Master Peace Officer — the highest law enforcement certification in Texas — bringing decades of criminal investigation, interview technique, and courtroom experience to every case.
Our COO, Cherisse M. Guerrero, holds a Master's degree and is a Licensed Professional Counselor (LPC). Her clinical background is an extraordinary asset in mitigation work, mental health-related investigations, and cases where researching is as important as gathering evidence.
Together, they lead a team that serves individuals, businesses, and legal professionals across Texas with discretion, integrity, and results.
