Creative, Determined Criminal Defense Attorneys In Charleston, SC

Bad things do happen to good people. Criminal convictions give you a permanent criminal record, which will show up on background checks for housing, work and educational applications well into your future. If you're convicted, it may prevent you from owning firearms, and it may seriously affect your financial situation.

Don't Surrender Your Future To The Scales Of Justice

Your future is in the balance. Just because you were arrested on suspicion of drinking and driving, committing a drug crime or other criminal act, it doesn't mean that you have to just let the state or county have its way with you.
