Fact: You will have absolutely no chance to win your DUI case if you choose the wrong attorney.

Just as you would not go to a doctor who specializes in foot-related issues (podiatrist) for brain surgery, don't trust your liberty, your life and your driver's license to an attorney who takes any old case that walks in the door. You deserve not just a good attorney, but rather the very best qualified attorney to help you.

Testimonials

Justin is the top DUI defense attorney in Pennsylvania. He gets great results for his clients through hard work.

- Attorney Brian Leininger

I am a single mother and because of work could not spend enough time watching over my son. Unfortunately, he became involved with gangs and out himself in a very bad position. One of his friends was involved in a homicide and my son was being charged as well.

My sister recommended Justin McShane and we decided to have him represent us. He worked really hard and was very prepared. He cross-examined every witness and in the end my son was acquitted of all of the felony counts and left with a misdemeanor.

When I took my son to Mr. McShane’s office to thank him, he went out of his way to talk to my son about his involvement in gangs. He explained how serious these charges were and that if he continued in that way he could get into a lot of trouble. It looks like my son took that to heart because he has been staying at home more and we’ve been talking about getting him back into school.

Thanks Justin. You’re not only a good lawyer but a good man with a golden heart.

- TW, Harrisburg (Criminal)

Justin is very hard working and extremely knowledgeable about DUI defense. Justin has impressed other members of the National College of DUI Defense with his understanding of the science behind these cases as well as the depth of his library – not something easy to do.

- Attorney Bob Keefer, Attorney, Keefer Law Firm PLC
