Established on Experience. Driven by Truth.

Klein Investigations was founded in November 1992 with a clear purpose: to provide reliable, professional investigative services rooted in integrity, accuracy, and discretion. From the beginning, the firm has served clients facing complex and sensitive matters—where experience, judgment, and trust are essential.
 
As a family-owned firm, Klein Investigations has remained committed to high professional standards while adapting to the evolving demands of investigative, security, and legal work. Over more than three decades, our team has supported government agencies, law firms, and private clients across Texas and beyond.
 
Our work spans investigative services, personal protection, and legal support, with each assignment approached methodically and without unnecessary attention. We believe that the strength of our firm lies not in volume, but in consistency—handling each matter with the same level of care, confidentiality, and professionalism that has defined Klein Investigations since its founding.
