Geoffrey is not only a good lawyer but also has an amazing team. Throughout the whole process Geoffrey was very thorough, attentive, honest, sincere, and was willing to go above and beyond to make things right. I trusted him from our first conversation and I’m so glad I did. He truly cares about his clients and his profession . His dedication is just simply unmatched. I would recommend him and his services to anyone looking for an amazing lawyer or consultant. Hands down a great experience from start to finish. Truly way more than just a defense attorney!
