SF & Bay Area Investigations provided exactly the level of professionalism, compassion, and…read moreexpertise I needed during an extremely distressing time. I recently discovered a financial statement showing the purchase of tracking equipment--while a criminal restraining order was in place against my ex. After everything I've been through, it was alarming and overwhelming, and I found myself constantly looking over my shoulder and feeling unsafe in my own daily routine. I worked directly with the owner--we'll refer to him as "D" for the sake of privacy--and from the very first conversation, he created a safe space for me to explain everything in detail. He didn't rush me, didn't minimize anything, and offered knowledgeable, grounded guidance that extended far beyond the standard vehicle sweep I initially called about. His professionalism was matched with genuine compassion, which made a huge difference given the circumstances. When it came time for the vehicle sweep, D was incredibly thorough. His process was meticulous, transparent, and clearly rooted in extensive field experience. What stood out most was how present he was--tentative, patient, and highly focused on ensuring every inch of the vehicle was checked. Even after the sweep, he continued to support me by answering follow-up questions and helping me process lingering concerns. If you're considering PI services--especially if you're dealing with something sensitive, frightening, or emotionally heavy--I cannot recommend this company enough. D listens, understands, and takes your safety seriously. His combination of expertise and empathy provided me with peace of mind at a time I desperately needed it. SF & Bay Area Investigations is absolutely a top-tier PI service, and I'm incredibly grateful for the care and professionalism I received.

Even when I said lets move on without add-on he refused. He also didn't like that I didn't have a lawyer and didn't know exact format needed for a court. Investigation I needed was time sensitive so it by the time I could even find someone else evidence was gone. It seems he's a nice person, but if you have something urgent and high stakes talk with many simultaneously.

Jason DeWitt helped me tremendously throughout a lengthy process dealing with a violent stalker…read more Jason helped me set up a camera on my property, helped aid me with how to connect with the police and how/when to make police reports. He helped me serve papers to my stalker safely by hiring additional security, and accompanied me to the following lengthy court proceedings. Dewitt helped me connect with a key, hard to find witness (a bystander who had made a 911 call on my behalf) and talked to them when I was too busy with work. This witness ended up being critical to my DVRO hearings, where I ultimately succeeded in getting a DVRO in large part thanks to DeWitt Detective Agency! When my stalked later violated the DVRO Jason consulted with me on how to proceed. Jason is a really nice guy, and made the whole incredibly difficult process a lot easier and more comfortable. He checked in often, and was available to answer questions whenever I needed. Recommend highly!!

All of our efforts to reach her failed and we began to fear the worst. Trying to find a good detective who will act as a partner is a difficult enough task when you have all of your wits about you. But when you are upset, worried and emotional, you can't think clearly. Jason was a breath of fresh air. He helped us locate our friend and get her the help that she needed to get back on her feet. I definitely recommend him.
