Top Rated East Bay Private Investigator

We are the top investigator in the East Bay. Clients review us in two places on Yelp: Spencer Investigations of Oakland and Spencer Elrod Services in Walnut Creek. The reason for this is Spencer Investigations was the original business name and listing, founded in 1997. Out of a total of 26 reviews, 23 reviews are 5 stars. The only three negative reviews came from people we turned down and who never hired us. We refuse business when it’s not legal, ethical or a good fit.

Yelp filters reviews in strange ways. As a small business we appreciate customer loyalty. But, a few great reviews never appear. We helped a robbery victim when police did not investigate. We saved a man from prosecution in a child abuse case. Our detective work cleared the man and saved his job. We helped another client and his lawyers win a civil case.

We win cases. We commit to our clients. We do quality criminal defense, surveillance, personal injury, civil cases and more. We charge fair rates but are not cheap. We strive to give clients honest and accurate information.


-Mike did an outstanding and professional job for me. His swift, thorough, and professional investigation enabled me to avoid more severe damage to my reputation. I cannot begin to thank Mike enough for his dedication and integrity and willingness to dig in and quickly find the truth. I would be happy to have a conversation with anyone who would like more detail.


-I hired Mike Spencer after I was robbed at gunpoint in Oakland but the Oakland Police Department refused to investigate, even though the robbers had left a clear trail by using my credit cards shortly after the robbery. Mike quickly and efficiency obtained surveillance video of the robbers making a purchase at the drive-through window of a local fast-food restaurant, after which he tracked down the owner of the car they were driving, but incredibly the Oakland police refused to do anything further, saying they were overwhelmed with a backlog of several thousand armed robberies and mine was “at the bottom of the pile.” The police were pathetic, but Mike was marvelous. I recommend him very, very highly.


-I utilized the services of Spencer-Elrod recently. Mike Spencer was very professional and discreet. At the initial contact, he collected the necessary details and made recommendations that led to a well-thought-out plan. He also seamlessly worked with my legal counsel effectively forming a team to best achieve my goals. His experience and background allowed him to dismiss impractical or unwise ideas leading up to the plan. He executed the plan in a timely manner and was extremely thorough in its execution and documentation of activity.

As conditions became more challenging, he was quick to work with me and my counsel to formulate alternate plans, again and again. He was able to recruit additional personnel and resources in an ‘out-of-the-box’ fashion in order to get the job done.

Eventually, his work required write-up and submission to the courts to proceed legally. He worked well with my legal counsel on this.

It was clear that Mr Spencer treated my final objective as his objective rather than taking the position that he had fulfilled the services of the original plan regardless of whether my objective was achieved or not. And just as importantly, the additional work required of him was all performed within the original retainer. – there was no ‘nickeling and dime-ing’ even when I asked him on occasion to look into this or that or follow-up on a side lead.

I would definitely use the services of Mr Spencer again and recommend him to others.
