Many thanks

The legal process is a long and tedious ordeal, but Mark was an excellent attorney. He listened to my concerns and worked with me for a positive outcome. Mark was always ready to answer my questions, which there were many. Mark did find an additional $22,600 fee that was improperly used by the T...rustee and it was returned to the Trust.

Excellent Trust Litigation Attorney

I hired Mark Ross to help me with a corrupt trustee who we eventually were able to get rid of despite her spending nearly all trust assets defending herself using the most expensive law firm in Orange County. Throughout the 5 years of struggle, Mark's billings were clear and reasonable. He did an e...xcellent job of keeping me informed of everything that was happening, was open and considerate to my input, and responsive to my concerns. Mark kept up with all critical dates and timelines despite having several other cases. Mark's judgment was good in that he advised when to fight and when to accept and settle. His focus was on my welfare, not just generating fee income. We didn't win every battle, but we won the war.

Favorable Settlement

Atty Ross negotiated a very favorable settlement with opposing counsel on a complicated Trust/Probate matter worth hundreds of thousands of dollars to me. He always did what he said he would do. Communication was excellent and he returned phone calls and emails promptly. His advice was well worth th...e expense of his representation.

Highly Recommend Mark Ross.

I hired attorneys from two different law firms to handle a real estate matter stemming from my divorce case and I was very unhappy with their services. Thankfully, a good friend of mine referred me to Mark Ross. When I called Mr. Ross to set an appointment for an urgent matter, he made the extra ef...fort to see me the next day. Mr. Ross is a highly respected, skilled, and very knowledgeable attorney. I would highly recommend him and will use him for any future legal matters. He stayed on top of my case at all times. He handled the case with so much professional integrity. He was honest and transparent about the time he billed me for. My case was resolved much faster than I ever expected, with greater results than I was expecting in the end. Thank you very much Mr. Ross!

RELIABLE, TRUSTWORTHY, KNOWLEDGEABLE ATTORNEY

I highly recommend Mark Ross and his staff at the Ross Law Group. Mr. Ross has represented me for over 6 years in several lawsuits as well as transactional matters such as negotiations and contract drafting for real estate and business transactions and continues to represent. Mr. Ross obtained an ...over $100,000 trial judgment for me, several settlements totaling several hundreds of thousands of dollars and a default judgment worth over $2 million. My business requires me to travel overseas frequently and my trust in Mr. Ross is so great that I have given him power of attorney to handle many of my business affairs when I am unavailable, which he does in an effective and efficient manner. On at least two occasions, Mr. Ross has taken time out his vacation to respond to business problems that required immediate legal response. Mr. Ross' staff is equally professional and responsive. I have worked with many attorneys from both large and small firms in the past and I have never received the attention or results that I have received with Mr. Ross and his staff.
