As I write this, I sit dumbfounded. Miss Ashley Morgan and Mr. Liles helped us with a problem we had in our medical practice, If you are a physician and are in need of an excellent attorney, I cannot recommend them more, I can not insist more to do your self a favor and contact them. Whatever legal troubles you may be having, or maybe its not troubles but you need legal advice concerning an acquisition, you really need to contact these great folks. I will probably just sit at my desk for the next hour in sheer amazement and gratitude for the great job they did for us. Seriously, call them, don't wait till the last minute, don't put this off, get them on the phone. They can help you, It is well worth it to save yourself the stress and the uncertainty of having to do this on your own. Call them.

I cannot say enough good things about Robert Liles. He successfully represented our company in a Medicare audit (due to technical errors) and was able to resolve every line item. Mr. Liles made himself available when we needed to speak to him and was very diligent in his work. He interpreted letters, rules and proceedings in verbiage we could understand. I would recommend Mr. Liles to anyone in need of representation.

I work for a training institute that helps physicians and their staffs run more productive and compliant medical clinics. I have had the pleasure to work with Robert Liles and his team of attorneys and legal experts for about 15 years at our national conferences for medical office professionals. He is a renowned healthcare compliance attorney and popular presenter. I am always impressed at the time he takes to answer attendee questions one-on-one after his sessions.

I have been using Liles Parker for managing all legal and compliance matters arising in our clinical laboratory. The range of expertise is broad. They have helped me with company formation, regulatory licensing, developing a comprehensive compliance plan, setting up medical billing and many day to day questions. From the beginning, I have been extremely impressed with their efficiency, common sense approach and wealth of experience. It is kind of funny that I will call Jennifer Papa(Papapanagiotou) with a question and she will reply "I just worked on this issue with another client, and here is what is important.....

Fantastic team. Lorraine Rosado and Robert Liles know how to win and win big. I would have not been able to do it without them. Their tireless support was what kept me, my staff and my family going.

Needing a lawyer is never fun - However, Ashley at L&P made the experience as comfortable as could be expected. When I needed a healthcare attorney with knowledge, experience and the ability to text back in a timely fashion I found Liles and Parker to be more than qualified - they were excellent. Could I have found a cheaper option? Maybe- but there are a few things you never cut corners on: toilet paper and lawyers... I couldn't recommend them any higher..

When I previously worked with an in-house legal team for a large national health care provider, we routinely relied on Liles Parker to handle all of our provider Board of Physician / Medicine responses. In over two years of handling every provider matter, we never lost a case thanks to the expertise and experience of Liles Parker. I highly recommend this firm.
