About

Please call first as we do not take drop in appointments at this address--it's where we get our mail. We are selective about what we take and because of case loads and other reasons, not every case is a good fit for us or the potential client. Investigations for law firms, businesses and select private clients. Focus is on surveillance, background checks, locating people, civil matters and criminal defense. We prefer to work through an attorney because attorneys often provide the best guidance about what evidence will help in court. We select each case and client on a case-by-case basis. We usually can't take cases in boyfriend/girlfriend matters or if there have even been restraining orders in a relationship. Our database terms dictate that we can only use databases for locating people in certain situations. We do not find old flames or former friends or classmates. Our team of surveillance operatives is experienced and gets the job done. We handle divorce and domestic, family law situations and insurance defense investigations. Surveillance in the Bay Area presents unique challenges but we often get results. We have great knowledge of public records laws and local courthouses. An advantage of being in business for so long is knowing where to look for information.

Established in 1996. I started the business after being a police and investigative reporter at daily newspapers in Virginia, Florida and California. I have a master's degree in journalism from UC-Berkeley, where my thesis earned a faculty honor. Prior to passing the state exam and earning my license, I worked under other investigators doing criminal defense, workers' comp and other types of cases. My experience as a journalist makes me a savvy interviewer and knowledgeable about public records. We also have an office in Walnut Creek, California. We are ethical, effective and smart. If we do not offer a service, we can put you in touch with a colleague who specializes in what you seek. A quality investigation takes time and resources. Thank you for your consideration.

I lost communication with my son for two years and was going to travel to see it

I lost communication with my son for two years and was going to travel to see it on his last known address. Looking for help on the web I found Spencer Legal Investigations. Contacting them was a blessing, I'm located on the East Coast and was going to travel to the West coast to look for him. Spencer Legal in about 30 min was able to find that he was no more on his last address and move to the East Coast. Today I was able to meet with him at the same place that Spencer gave me. Im still in shock....however very happy to see my son again.

Mike is really nice guy. He didn't take my case because there wasn't much he could do, but he took the time to talk to me anyway and gave great advice on what my next steps should be!

I recently had a situation with a fraud purchase at our dealership, and was having trouble locating the person. I contacted Spencer Investigations to discuss the situation, and see what they could offer to help. Mike was very professional while talking on the phone, and once hired, and placing a retainer he started working on the case immediately. Mike kept in close contact with findings, and provided updates regularly. Fortunate for us the person was arrested with in a couple of days of hiring Spencer Investigations. I contacted Mike to let him know, and was issued a refund of the retainer that was not used the next day. I can not recommend them enough. Very satisfied and will contact with any PI work we may need in the future!!!

I did not actually get service from Spencer however I did inquire. The fact that he got back to me right away and was honest in explaining why he wouldn't take my case was worth 5 stars to me. My case was a car theft and he couldn't do anything that I myself or the police could do and he didn't want to take my money. I really appreciated that! He did give me some great tips on things I could do myself. I have no doubt that if you have a real case he would be your guy!

PI Mike/Spencer Investigations is a reliable and sound Private Investigation Service. My family hired him to do some work investigated Rental Fraud and he was able to source some key information that helped us in court. Prior to knowing Mike professionally I knew him as a teammate and friend. I have nothing but respect and good things to say about him. If you are looking for someone to listen to your story and find the information or evidence you need, look no further than Spencer Investigations.

This is a review for my co - worker as she does not have a yelp account here are her thoughts on her experience : After months of researching I was trying to find my biological father and coming up with very little. I found Mike and within 48 hours he was able to answer all of my questions. His service was very fair priced and my siblings and I are able to find peace with the results. Thank you Mike,

Unfortunately, I was in need of a private investigator. I was trying to find someone that was incredibly hard to find and I emailed Mike with all the details. Mike called me back within the hour. Mike was upfront and direct with me, while he wasn't able to take on my case. He was able to help me and provide information about the person I was looking for which lead me to find them on the same day. I can't thank Mike enough for helping me. I was trying to play private investigator and trying to find the person myself, I was able to piece together bits and pieces of information with my own detective work (My Google-Fu is very strong too). But, Mike was able to provide me more information in 1 hour then I was able to gather in 2-3 days. Save your time, reach out to Mike to help out with your investigative work. If I ever need a PI again, Mike will be the first person I call.
