This review is from a person who hired this attorney.

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.

This was not posted by a client. This was posted by an opposing party who I went after for committing financial elder abuse over an elderly woman. I was successful in gaining control over the situation and ultimately ensuring that the family obtained the woman's home after she passed away rather than this criminal.

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.

Good attorney

I hired Mark for my Trust: Loi Lam Qualified Domestic Trust. Mark is not cheap but he does his job. Before Mark, I had two more attorneys. They did not know how to get things done. Mark is a knowledgeable attorney to handle any Trust/Probate case.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
