I want to thank attorneys Tim and Robert and the paralegal Bethany for all they had done on my case. They were all empathetic, knowledgeable and professional. All my questions were answered, emails returned in a timely matter, and promises fulfilled. I recommend Phillips Law Group if you need help with your injury case.

Great experience! Took care of pretty much everything, and I always felt like I want in good hands. Caroline Fa. was also a great help with everything. She always returned my calls and I never felt unheard. Even after my case she would still help me with my insurance documents.

I have been with Phillips Law Group for a little over a year and I have learned what teamwork and family in a workplace looks like. There is always someone around to lend a helping hand, which is something I appreciate and cherish. I feel a sense of joy coming to work every day because of my co-workers as well as being able to help people in what can be a scary and stressful situation. I currently work as a Litigation Legal Assistant with an amazing team. When I started here, I was not very knowledgeable in personal injury. I was lucky to have been placed with an amazing team who was willing to take time to teach and pass on some great skills that have been a huge aid in helping me be successful in my position. I would recommend working here at Phillips Law Group, because they care about their employees and there is so much room for growth.
