Attorney Grossman is an excellent counsel and advisor, knowledgeable about Family Law, Divorce and spousal domestic abuse. He listens to your psychosocial history and engages you in the laws and in the California state regulations, as well as the various legal strategies to your family problem. In my case, he explained the complexity of filing a civil suit for female on male domestic physical injury/abuse, while also filing a divorce claim in sequence or concurrently. Attorney Grossman is kind and sensitive and acted not just as competent legal counsel, but also like a rabbi/pastor and health coach. I will be back to see him next,soon, for a Family Trust contract, if I am blessed enough to avoid divorce first. FIVE STARS FOR ATTORNEY MARC GROSSMAN!

I was referred to Mark Grossman from a family member. Mark took his time to understand my case and giving me some options. Generously took the time on the call. He even took my call when I had additional questions the following day. I would recommend Mark for any of your legal needs.

I consulted Atty Grossman on an issue. I described it on the phone and he suggested a f/u meeting after he reviewed my case. At the meeting, he gave his opinion, straightforward and honest, and the various scenarios of next steps. This was very helpful to someone like me trying to navigate the legal system. Kudos to Atty Grossman

Marc was wonderful to work with, very professional and straightforward. His attention to our family and our situation made us feel at ease and protected. He was incredibly knowledgeable and experienced. I strongly recommend his legal services to anyone in need of a solid attorney firm. You won't be disappointed.

No star, Marc Grossman doesn't deserve not one at all, but it wont post without at least one star. The mismanagement of my divorce case cost me thousands of dollars. Mr. Grossman handed my case to his law clerk and my case was rejected twice due to in house office mistakes. I paid the initial agreed amount, paid an additional amount to correct the first rejection (missing forms). When I emailed Mr. Grossman whom had no contact with me during this whole time, he responded with such aggression and unethical behavior. Three and a half years later, paid him thousands and I am not divorced. I filed and went to child support court by myself,. I'm unable to recover back owed child support or unpaid debt. So disappointed by Marc Grossman, I would never ever tell anyone to use his services. Don't use him, because you need an attorney who is looking out for you, not one who's only interest is his own monetary gain from you.!!!
