Thank you Bob!
I had a tough situation related to accountant liability and I was so depressed and frustrated before I met Bob. He helped me create a clear and advanced strategy about how to process and defend myself. I followed all of his advice and tried my best to provide the supporting documents. Eventually, I got a very nice result from the case. I feel I was so lucky to meet Bob and got his help. Many thanks to Bob and his team!

Robert H. Cox, Esq. -
I had the good fortune and privilege of legal representation by Robert H. Cox (“Bob”) in a matter before a professional state regulatory board. As an attorney, myself, my respect and appreciation of Bob grew throughout his representation. Bob represents the very best of what we expect from our legal profession and his stellar ranking as an attorney by the profession is well deserved. Bob’s legal skills, broad and deep knowledge of the law, and “people skills” are apparent. My particular matter involved very complex and convoluted facts which Bob was able to ferret out the relevant facts to cite in support. Moreover, with Bob’s in depth knowledge of the law, he applied some sophisticated legal concepts including citation of pertinent case law. Beyond Bob’s keen legal knowledge and skills is his communication and people skills. Much appreciated is how Bob collaborated with and kept me informed, throughout the process. Also noteworthy, is a first-hand observation how judicious and conscientious Bob is with his time in his appreciation of his client.

Smart and hard working but above all, an honest and very compassionate lawyer. Understands the situation from the onset and from the first visit you feel that you are in trustworthy hands. Bob will not let you spend unnecessary legal fees. I highly recommend Mr. Robert Cox. I could not have asked for a better counsel.
