    I have known Attorney Walsh since I started practicing law. He is very knowledgeable, skilled and hard working. I have seen the results he has obtained for his clients and am impressed by his commitment to fighting for what his clients needs and what he believes in. I would not hesitate to retain Attorney Walsh if I had an issue in this area.
