I cannot thank them enough they helped me track down a slippery sub-contractor who had eluded every attempt to get their TIN but would convince the staff of the company I work for to continue paying him. I can confidently file 1099's for this year.

Extremely professional and very helpful! I had a lot of questions and Gwen was extremely helpful in answering them. They were very prompt on responding to me. Let me add I was in a completely different state and I felt secure that they were helping me. Highly recommend!

Lance Casey served opposing party and was supposed to file the original signature with the court. That's what we paid him for. Our case has been negatively effected by his negligence. Not only that, but it took weeks to get him to actually mail us the original signed proof of service. His outgoing message says to text or call his cell and he'll reply, but he never responded. After a dozen calls, his assistant was rude and acted as if somehow we were at fault for their screw up. Do NOT use them. They are very unprofessional.

Lance served my first and hopefully last small claims. He was fast, and responded quickly. He served CSC in Sacramento, quite far away from me. Thanks!
