I have a situation where I need the services of a white collar lawyer, but I don't quite know how to choose a reliable one. Can someone suggest where such lawyers work?

I faced a similar situation when I needed to find a good lawyer for white collar defense. I was recommended one firm that handles such cases and the guys are really knowledgeable. This link here has information about them. They specialize in defending in these types of cases and will be able to help in a difficult situation
