My daughter tells me that when I go to work every day, I try to help people. She is three. It is a cliche but she gets it. The court system is complex and the legal process is difficult to understand. I have devoted my life to trying to help people successfully navigate that system in an effort to obtain some sense of justice. It is a hard job. Sometimes it works out as planned and hoped. I like when that happens, of course. Sometimes the best lawyer is the one who tells the client what they really do not want to hear, and what makes them angry (sometimes at the lawyer unfortunately) but its the truth and will hopefully save them time and money in the end.
I litigate. I do not shy away from challenges. I take cases to trial. I battle Goliaths. I represent a broad range of clients. I try to handle every case the way I would want my case handled. I work hard and endlessly trying to make sure that everyone who hires me feels like the system works for them. If you have a legal matter, feel free to contact me. I am licensed in Pennsylvania and New Jersey and practice in the federal and state courts in both states. I was born and raised in the Philadelphia area, and went to college in West Philadelphia at the University of Pennsylvania and law school on the Main Line at Villanova. I am a hometown lawyer.

A great attorney
When I was fired from a previous employer for having a disability, I thought that there was nothing that could be done. Then we found Mr. Koller, he told me that I did have a case and was able to help me through the procedure. I had a successful outcome and am very grateful for all the help and advic...

Wage Payment Collection Case
The Koller law team is extremely professional and responsive. David helped me with a wage collection lawsuit which ended in a judgement in my favor. I am confident that his knowledge of the law, calm demeanor and persistence were what won our case. I would highly recommend him to anyone dealing with ...

Sexual Harassment Case
Atty David Koller knows his law... He helped me win my case against a previous employer for sexual harassment, and hostile work environment, that I thought I didn't have a chance at winning. He talked me through the hardship that I went through, and was very supportive throughout the entire case. H...

Great personel service
David was a straight shooter who told me exactly where I stood and the strengths and weaknesses of my case. He was responsive and made a painful process much more tolerable. The best thing was he did what he said he would do when he said he would do it. Overall a great experience with very good re...

Just wish I would've went to Dave first. He was a ray of light in a very dark time for me.
After suffering illegal retaliation, threats, harassment, and termination from my job of 10-years for being the only one who would report abusive mistreatment in the workplace when everyone else was scared to speak-up, and subsequently learning the hard way the truth about gross corporate corruption ...
