Operating a successful intellectual property law practice is my life vocation.  I endeavor every day to provide top notch services to my clients through my law practice, with my team of professionals.  Outside of work, I spend time with my wife and three boys who are my everything and the reason I work so hard.  I enjoy being outdoors, and I spend as much time as possible in the Poconos.  Music is a big part of my life.  I’ve played various roles in bands as a bassist, guitarist, and vocalist.  I also enjoy genealogy research, old trucks, tinkering with electromechanical devices, and software development.
