I'm really grateful for Google reviews. I had been referred to a lawyer in San Diego (Not San Diego Business Law Firm) for my LLC formation needs and after reading their Google reviews, I think I dodged a bullet. So I looked up other lawyers in town and found The San Diego Business Law Firm with extremely high reviews. They certainly lived up to their reputation. I called them up and every single interaction and step of the way was first class service. Additionally, we all know lawyers are expensive and I was pleasantly surprised that for the level of service they were providing the fees were very on par with others I called. Thank you Marwan for the excellent service and communication. You will be my preferred legal servce provider from now on!Posted on Jess LindgrenTrustindex verifies that the original source of the review is Google. Marwan and his team are the best!

I cannot thank Attorney Marwan and his team enough for how they handled my case especially considering I had very little time and was under immense stress. From the first moment, he didn’t just follow a standard plan,he anticipated what could go wrong, remained two steps ahead, and crafted a strategy that gave me hope. Within just ten days of signing with them, the entire lawsuit was dismissed. He took control when I felt completely out of options and treated my situation with the urgency and compassion I desperately needed. He didn’t just do his job,he made me feel safe, seen, and confident through each step. If you are looking for someone who truly fights for you, stays ahead of the curve, and brings results when time is tight, look no further. I highly recommend him and his amazing team.Posted on Bayanne MihtarTrustindex verifies that the original source of the review is Google. I recently needed assistance starting a 501C 3 for a nonprofit. I was referred to Mr. Sanoufi by a friend. Even though 501c3 is not Marwan’s specialty he was gracious enough to walk me through the process pro bono. He was so thorough that I was able to complete the entire process following his instructions. His kindness saved our nonprofit thousands of dollars. I would highly recommend The San Diego Law Firm!Posted on Wasim KamalTrustindex verifies that the original source of the review is Google. Marwan is a very professional and trustworthy attorney.
