Honest, Trustworthy, Respectful, Caring, Hard worker

Mark is an amazing person and he goes out of his way to make you feel like family. He also stands up for you more then you could imagine. He will fight for you and never give up. He is extremely loving and kind but don't forget that he is a lawyer and has that side of him fighting for you at all tim...es. Mark is the very best at what he does. He has been in my life for a long time and it is hard to think about not having him calling to see how I am doing. I also want to add that Mark has a great team behind him. Gay is amazing at being there for you no matter what you need. I just want to thank them for helping me through one of the hardest things I have ever been through.

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

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.
