We have served Oakland and Bay Area attorneys for nearly 30 years. Moreover, we handle criminal defense cases, personal injury matters including wrongful death, and family law investigations. We are where experience and enthusiasm come together. It’s all about helping lawyers and their clients win!

Oakland is a unique, diverse city. Private investigator Mike Spencer and assistant investigator Angela Rowen know the city well. We work in the neighborhoods and institutions. Therefore, we are the private investigators for Oakland attorneys.

Witnesses make cases in criminal defense and other legal matters. We know how to get witnesses on your side. We are ethical. If it’s in court, you need private investigators who take the high road to testify. Not all private investigators are capable of building rapport. Spencer and Rowen are both former newspaper reporters. Positive results matter to us.

We work well with law offices, whether solos or larger firms. Therefore, communication is the key. We come up with a game plan. We execute the plan. We consider the budget for each case. You can expect updates every two to three weeks, a quality necessary as a private investigator for Oakland attorneys.

Spencer has handled hundreds of court-appointed criminal defense cases in Alameda, San Francisco, and Contra Costa counties. Additionally, Spencer works on federal cases and appeals. Responsiveness and integrity are the qualities you want in a private investigator for Oakland attorneys.

Spencer and Rowen update their training. They attend a variety of seminars on criminal defense and civil investigations. They do social media sweeps. They scour courts for relevant records.
