  • This is the best personal injury lawyer in San Diego. I got into a car accident while driving in downtown San Diego. I suffered a neck injury. I was going to be out work and lose my personal pay.

  • In life, you meet a few people that really change it for the better, one such person is Dan Gilleon. I have Complex Regional Pain Syndrome (CRPS) and Dan took this difficult personal injury case, which could have gone either way on a decision. From day one Dan started working meticulously and never stopped working until we received just compensation. If you want a smart, honest, non-stop bulldog, there’s only one man I would recommend- Dan Gilleon. I can’t thank him enough.

  • I fully knew what to expect and was informed every step of the way.
