I would recommend to look for others at the same time as you're talking with Mark because for me he…read morerefused to proceed with a job when I asked if it's possible to get an addon of digging into nature of previous misdemeanors (some of which may or may not be juvenile) just before I was ready to sign a contract. 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.

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.
