Owen Matthew Seman

About Me

For the past 10 years I have worked in one of the busiest criminal defense practices in Western Pennsylvania, handling everything from minor traffic tickets to Homicide jury trials.  When someone gets charged with a crime it is essential that they have an experienced and knowledgable attorney to be their voice and to protect their rights.  I know that when someone comes into my office they are dealing with one of the toughest situations in their life, and I treat each client with respect, care and dignity. 


In criminal cases no attorney can promise you a particular result, because there are so many unknown factors.  I can say I will do everything in my power to get the best result possible.


Please feel free to call me for a free consultation.

    Owen is one of those guys that is not only very good at his job, but he's a hell of nice guy too. In a business that values relationships to get things accomplished, you can't get a better combination. I'd highly recommend Owen to anybody who needed a solid criminal defense attorney.
