I have used Thomas Martin’s services for many years and have found his work to be of the highest standards. He gets the job done quickly, efficiently and reliably.

Successful people know that to be the best, you model the best. I cannot recommend Martin PI any higher! In a five minute conversation with experienced people you can save thousands by bypassing sales types. They do this by cutting directly to the heart based on years and years of passionate pursuit of best practices and adding massive value to their clients. They are an invaluable part of my team and Tom is my most valued mentor!
I truly cannot thank Tom Martin from Martin Investigative Services enough! I have been searching for over ten YEARS for my biological paternal grandfather and kept coming up short because A.) he was a drifter before the age of social media and B.) both my father and grandmother had passed and took all knowledge of his existence with them to the grave. I had no knowledge of his real name, birth date, address, et cetera.
I finally had enough and scheduled a meeting with Tom Martin. I told him how desperate I was to find my grandfather and gave him what very little information I had. Martin Investigative Services found my grandfather within HOURS of our meeting. It turns out my grandfather also lives in California and I was able to meet him two days later. Not only did he have my grandfather’s address, but he had spoken with his sister and his mother. It turns out I had a great-grandmother and great-aunt that were excited to speak to me!
The resemblance between him, my father and myself is uncanny. If not for Tom and his team, I would never had been able to fill the hole in my heart and finally solve the mystery my father was never able to in life. They provided my with family I never knew I had and I’ve finally (!) been able to fill my family tree. Thank you, thank you, thank you M.I.S.!
It has been my pleasure to work with Martin Investigative Services over the past 30 plus years on many investigations as well as other security related matters. When I need answers and I need them fast I know that a simple call will get me answers that are succinct, current and coming from a supremely knowledgeable source.
Absolutely THE BEST! Engaged Martin Investigations to locate my son who decided to disappear from my life. It had been over 10 years since we last saw each other. Where others had failed miserably Tom Martin took on the task and was able to locate my son within hours. Tom provided me with my son’s current address, phone number and even my son’s E-mail address. Fair pricing, upfront explanation of what I could expect and quick service, this was money well spent. If I could give Martin Investigations a 10 star review I would gladly do so. Thank you Tom!
Wow! What great service! I requested the information I needed to find a family member that I had never met. I have been looking for this person for over a year.
Within 1 hour all the contact info was e-mailed to me about this family member. I waited until the next day to try to contact them. The first phone number I called the person I was looking for answered my call! The first thing the family member said was how did you get this number? I had tried all those online services that claim they have special information but all I ever got were more old number and dead ends. What I needed was the personal service of Martin Investigations. I talked with him on his personal cell phone and he was ready to answer my questions. I was able to have dinner with this family member that night and they brought family photos of my biological Father whom I had never met that had since passed away. I am in the process of building a relationship with this family member that I had never met and I am confident I have made a new friend!
Thanks Thomas Martin!
I am proud to state that I have exclusively used the professional services of Tom Martin and his firm for more than 20 years. Whenever the need arises for a private investigator, the only name that I consider for my clients is Tom. In my 40 year career as a family lawyer, I recognized the importance of professional investigators. Unfortunately, many of the investigators that I have encountered have not satisfied the professional standard that I expect. I have utilized the firm in some very delicate and discrete investigations and situations requiring a strong security presence. In every engagement, both my clients and myself have been completely satisfied. I have I have no reservations in endorsing Tom and his firm for any investigative assignments.
I have worked with Martin Investigative Services for our company investigations for close to 20 years. Tom and the team are always professional, skilled and get right to the heart of any assignment I have for them. I would highly recommend Martin Investigative Services for any workplace investigation.
My partner and I have utilized the services of Martin Investigative Services for in excess of 15 years. The services provided have ranged from simple background checks to covert surveillance and investigations into corporate malfeasance/conversion/theft of assets.
I have found Martin’s investigators conscientious, qualified, and most important of all, very credible to triers of fact when their testimony was necessary. Critical to any busy trial attorney is time. I have also found that upon turning an assignment over to Martin Investigative Services, I do not have to micromanage the assignment. It is done promptly and efficiently, with an eye toward the financial resources and capabilities of the client.
Tom Martin is thorough, knowledgeable and trustworthy. We have used Tom and his team to great success and will continue to do so.
