Adam Koelsch is an experienced local tax attorney, with a rich background in prosecutorial law. Adam joins other former city staff members at Chamberlain Hrdlicka, adding to the supreme legal insight coming from the firm in the practice area. 

Since 2015, Adam has acted as Deputy City Solicitor for the City of Philadelphia Law Department. At the Law Department, he represented the City in high-dollar-value/complex local tax cases at administrative hearings before the Philadelphia Tax Review Board. He was also involved in agency appeals and collection actions at the Court of Common Pleas, and in appeals at the Commonwealth Court.

Prior to joining the City of Philadelphia Law Department, Adam worked at the Kings County District Attorney’s office in Brooklyn, New York, one of the largest prosecutor’s office in the country. He first was an assistant district attorney in the Trial Division. While an ADA, Adam managed a substantial criminal case load.

In 2010, Adam moved to the Appeals Bureau in the District Attorney’s office. He became a Senior Appellate Attorney in 2012. During that time, Adam wrote many appellate briefs for the state and federal courts, in a variety of cases, including homicide and fraud cases.  In addition, Adam has argued on multiple occasions at the New York Court of Appeals, which is the highest appellate court in New York, and has routinely argued at the lower appellate courts in the state.
