“You want to read this!”

My daughter was arrested for a DUI and failed the breathalyzer. Friends said no attorney could get her off this. Well, they never met Michael- he was brilliant, no other word to describe it. Even the courthouse clerk told my daughter she had a good attorney and that he’s a nice guy. Michael - I thank you from the bottom of my heart for giving my daughter another chance with no criminal record.
