Criminal Defence Lawyer

The only thing standing between you and the state is your Defence Lawyer

It takes many years of practice to become a good criminal defence lawyer.  It takes hard work, focus, and the discipline to maintain those two things for a long time.  It takes a broad set of skills. A good criminal defence lawyer has to be good at public speaking, research, understanding people, comprehending complex and confusing evidence, rapidly making decisions and acting fearlessly to advocate for his client.  I’ve spent the last 20 years studying and practicing law to become the best criminal defence lawyer I can be.
