What Our Clients Say

4.8 out of 5 from 36 Google reviews

  • Several weeks ago I called multiple PIs in the area to inquire about PI services to support a potential lawsuit. Only one of the PIs I tried to reach actually answered the phone and the only one who did was Charlie, who personally answered my call. During the conversation, Charlie thoughtfully listened to the circumstances I described and gave me solid advice regarding how best to proceed. He was never in a hurry to hang up and move on to a more important case. I will most definitely reach out to Shawver & Associates should I require PI services again. In the meantime, Thank You Charlie for being a good human being who cares!

  • We recently had the pleasure of working with Shawver & Associates, specifically Charlie Downey, and were thoroughly impressed by the experience. Charlie assisted us with an urgent matter and demonstrated an exceptional level of responsiveness and professionalism throughout the process. Charlie’s expertise and talent are evident in his approach, and it’s clear he’s a true master of his craft. His credibility and dedication to providing top-notch service set him apart from others we’ve worked with in the past. This was, without a doubt, the best experience we’ve had with any professional service. We highly recommend Shawver & Associates, and especially Charlie Downey, to anyone seeking reliable and expert assistance.

  • Had nothing but a good experience with these PIs. I was emotional, given the circumstances of my case and he was completely patient and kind with me the entire time. His professionalism and thoroughness shined through, throughout the whole ordeal. I am absolutely thrilled with the results, that took no longer than 20 minutes for him to get for me. I 100% recommend them. They were not hard to get a hold of, and like I said...were very patient and kind which honestly made the whole negative situation into a positive experience for me. I felt like I was heard and like my situatuon mattered. Thank you so much again for your help. And if anyone on here is looking to get a PI, dont hesitate to use these guys you will not regret it.

  • Spoke to Charlie himself he was very helpful. I figured i would speak to a receptionist who would take my number but no it was him. Charlie is very nice and understanding. He actually listened to me without making me feel rushed. I could tell right away he was not in it for the money. He wanted to put a face to Shawver&Associates by having a meeting with me to talk about my situation in finding the dead beat sperm donor. That meant a lot to me. He found the guy the first day. I could not believe it. First time using a P.I. If i needed another i wouldn't go with anyone else.

Investigative Services in Houston and Harris County


Houston sits in Harris County, the most populous county in Texas, and its courts carry a correspondingly heavy civil caseload. Matters here rarely stay inside one county line: a claimant lives in Fort Bend, works in Harris and is treated in Montgomery. Shawver & Associates handles surveillance, background, insurance and family investigations across the Greater Houston area, and documents each file so it survives the scrutiny a busy docket invites.

Our diverse experience and backgrounds have enabled us to satisfy hundreds of clients who have saved money, avoided legal action, exposed injustice or reunited with long-lost loved ones.

Call Us

Counties We Cover from Houston


Assignments in the Houston market routinely cross into Harris, Fort Bend, Montgomery, Brazoria, Galveston, Waller, Liberty and Chambers counties. We plan fieldwork around that reality rather than treating a metro as a single point on a map, because a subject's home, workplace and medical appointments frequently sit in three different jurisdictions. Where a matter is heading for litigation, knowing which county it will be filed in shapes how the evidence needs to be recorded.

Insurance, Injury and Claims Work in Harris County


Houston's concentration of industrial, maritime and commercial activity produces a steady volume of injury and insurance claims. We conduct surveillance, claimant and witness location, background checks and recorded interviews for insurers, defence counsel and self-insured employers. Reports are written on the assumption they will be disclosed, so they record what was observed and when, without characterisation.
