Best criminal defense ever
John is very professional compassionate attorney.He was great to work with he represented my son to his fullest ability. He told us what he could do for our case from the start. And he did get the best resolution possible.. I would recommend him in a heartbeat.

For those reasons, I hold Mr. Brennan in the highest regard and am happy to endorse him in the area of criminal defense."
