David took his time and patience to make himself familiar with all of the details of my lawsuit, advised me honestly and used good judgment in handling the case. He kept me totally informed and kept me calm througout the ordeal. He took an upsetting situation to a positive end. His staff was equal...ly compentent, all calls and concerns were addressed within a very acceptable time frame. Through this entire process he and his staff worked efficiently to minimize costs and expenses. I would recommend Mr. Koller to anyone needing his expertise.

In 2009 I had a nervous breakdown, from the retaliation because of disclosure of a wrong doing. I had called several lawyers and no one responded because it was a government agency, Mr. Koller returned my call and has since not only found that the agency retaliated in that instance, but other factors... were disclosed. Since then I have recommended people to Koller Law, because he really works for you.
