Very great lawyer and public defender

Ms. Castillo represented my 82 year old father in his attempt to be released based on the compassionate release law. He had been incarcerated for 30 years for a non violent drug crime back in the 80’s. Ms. Castillo was professional, she knew the law, knew what she had to prove, and was Successful in my fathers release. What stood out to me was not only her knowledge of the law, but her communications (and there were many) with me. Every step of the way, she would take my phone calls, return emails and personal texts, that to me, was extremely impressive as lawyers I’ve dealt with in the past never do this. Usually, you will speak with their receptionist or an assistant, not the attorney him or herself. I highly recommend Ms. Castillo as she is a competent , committed attorney. She successfully won this case and gave a man a new life.
