I'd come to David after I felt I was wrongfully terminated from a job due to differential treatment based on gender. I knew I wanted to do something about being let go, but was nervous about moving forward and unsure if trying to take legal action would be a waste of time. David was reassuring and he...lpful from the start. He explained each step of our process simply, and his frank, but friendly manner of communicating really put me at ease at a time when my nerves were running high. I'm sincerely grateful for David's assistance with my case and for helping me find closure.

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...sults.

Mr. Koller represented me in a legal matter. He was amazing through the whole process. Always answered all of my questions and kept me informed of everything. Was also very honest and straight forward with me the whole time. I was very satisfied with the results in my case. Mr. Koller did an amazing... job. I would recommend mr. Koller as an attorney because of his professionalism, honesty, and his great attitude. I was always treated with respect and kindness by mr. Koller and all his staff. If you have any legal matters contact him because he will fight to get you good results just like he did for me .

I first met Mr. Koller and his staff (Erin and John Krawczyk) in December of 2010 in regards to false information on a background check that costed me various jobs. We worked on various cases together in regards to this matter. From the beginning, Mr. Koller and his entire staff took the time and ...explained all options available to me, worked tireless hours to investigate my cases, keep me informed of any developments and gave me the appropriate information to make the proper judgement in regards to each case. Because my case became newsworthy, I was invited to speak in regards to the "ban the box" law that allowed convicted citizens to apply for work without discrimination. I also was invited to speak in front of Pennsylvania congress in regards to ways to safeguard background checks by third parties. Mr. Koller supported my efforts by accompanying me to City Hall and also helped me prepare for my speech for PA Congress. I would heavily recommend Mr. Koller, Erin and John for any case in regards to their expertise, knowledge, business ethics and work ethic. They are a great team and will continue to give great legal services.
