I have set up more than 20 LLCs and S-Corps through KKOS. Mat has been the go to guy for IRA LLCs for years. I have never been told that "I don't know, I'll look it up and get back to you". Mat is a very knowledgeable real estate attorney. I have never felt uncomfortable with anything he has told... me or my business partners. He is very professional and I highly recommend Mat for setting up your companies and any questions regarding investing with retirement plans like IRAs and 401ks.
