From day one when meeting Dave for the first time I knew I made the right decision contacting David Koller, Esq. Dave immediately understood my situation concerning my disability and how unfairly I was treated, he truly cared. The support, knowledge and direction received from Dave and his team through the process was superior, all questions were answered and information required was a team effort, I never felt alone.




David Koller and his dedicated professional staff successfully resolved my disability case against my employer. Dave is not only extremely knowledgeable about the justice system and its participants but a concerned and caring person. He is committed to helping his clients not only financially but also in helping them to move on successfully with their lives. A good man with an excellent practice.



I am very grateful to Mr. Koller. After years of sexual harassment from my previous employer, I felt that I had nowhere to turn for help. Until one day I took that brave step to contact David Koller. From that day forward he made me feel confident that I chose the right Lawyer. David Koller and his team worked very hard for me. He responded to every phone call and email in a timely manner, which meant a lot. Not only was Mr. Koller just doing his job, but he was dedicated and sincere throughout the whole case. Needless to say, the case ended in my favor. I thank Mr. Koller, for helping me get to that light at the end of the tunnel. I would highly recommend him to anyone.

I was diagnosed with an aggressive rare cancer and because I fought it and beat it I continued to work, but needed a lot of follow up surgeries to repair the left side of my face that was removed and that became costly to my employer. I was out for a few weeks for another surgery but the day I returned I was let go. Lot more story behind this but the person to thank that helped me be strong and stand up for myself is Mr. Koller. I had nothing but positive experiences with his staff and had communication with them throughout. The day of our mediation I was really nervous but Mr. Koller was there for me and made me feel better about it. He kept me calm and made me feel safe. He has gone above and beyond to make things right and I would more than just suggest him to another client, I would insist upon it because I know you will be his priority and your best interest is at his heart and all of his office staff. Thank you Mr. Koller and all your staff that helped end a horrible part of my life.
