  • “We wouldn’t be here, in this moment of life without the kindness and professionalism of you all and how you went to bat for us! Eternally grateful!”

    - A.K.

  • “We could not be happier with the McCllelan Law Firm team! My husband and I were referred to Craig McCllelan by one of his peers. We had a very sensitive medical malpractice case that we were hesitant to even pursue. Craig and his team sat down and walked us through the entire process giving us their honest opinion and options. We felt very comfortable with the process and completely relieved by the end of the first meeting, so we decided to proceed. It is three years later and we couldn't be happier that we did. Craig, Connor, and his team made the entire experience so easy and smooth. They were always available no matter how small our question or concern. I swear they work 24/7! And most importantly, we knew that they truly cared about us and the outcome. They fought for our family and have given us the piece of mind that our son's healthcare will always be covered. It is truly the greatest gift and we will forever be in their debt!”

    - S.P.

    - G.P.

  • “Your appearance on the nation-wide broadcast of ‘60 Minutes’ was a public service in which all San Diego has reason to take great pride. To integrity—you have added public service and again elevated my opinion of the legal profession.”

    - Juror

  • “Having had the high privilege of presiding over a number of cases involving national counsel, I want you to know you’re one of the very best [...]. You and those with you were outstanding ambassadors for our profession and once again made me most proud to be a part of our legal community.”
