What you want from an attorney is sound advice and strong legal representation. Eric gave us both. Truly a professional and amazing how much he showed that he truly cared about us and our situation. We had really great results that I know doesn't happen for everyone, however even if the dollars were less, I would still feel like he took great care of us and did all he could. Thanks Eric!
