The Best Attorney
As a teenager, our daughter, as do many children of that age, made some poor choices. She was hanging with the wrong crowd and ended up drinking which lead to the involvement of law enforcement. We contacted Amanda Erwin and discussed the case. We immediately felt that she showed true compassion and understanding for our daughter's situation. We were very confident that her advice was in the best interest of our daughter. We scheduled an appointment to meet with Amanda and her husband, Josh. They were both wonderful! The sincerity they showed assured us that we were in the right place. Amanda and Josh took on this case as if it was their own child. They did what they said they would do. They fought for our daughter and had the felony charge reduced to a misdemeanor. Amanda advised us to have the charges expunged so that they would no longer appear on our daughter's record. So when it was time we hired Amanda to handle the expunction. Once again, we were extremely impressed with the way she handled the case. Amanda was adamant that this mistake should not follow our daughter around the rest of her life. She exceed our expectations threefold and we could not be more pleased with the outcome of the situation.
