About David Mikel
David Mikel Koller built a steady path into lawbound work after finishing his studies at the University of Pennsylvania and Villanova University School of Law. He earned his B.A. in 1999 from Penn and completed his J.D. in 2002 at Villanova. Those years set the technical groundwork for a practice that spans two states.
After law school, Koller spent the next several years gaining experience that led him to start his own firm. In 2009 he founded Koller Law, LLC. The decision to open a boutique practice allowed him to shape the firm’s day-to-day operations and the way it serves clients. As founder he has overseen case selection, client intake and the administrative responsibilities that come with running a small firm.
Koller is admitted to practice in Pennsylvania and New Jersey. He holds current memberships in the Pennsylvania Bar Association, the New Jersey Bar Association and the Philadelphia Bar Association. He is also a member of the Senior Law Center. Those memberships keep him connected to the regional legal community and to continuing legal education offerings that affect practitioners in both states.
Colleagues say he approaches matters with a practical sensibility. He favors clear explanations over legalese. Clients can expect direct communication and an emphasis on resolving issues efficiently. He manages legal work for individuals and entities that require counsel across state lines, and he coordinates filings and proceedings in the jurisdictions where he is licensed.
Koller’s education informs how he evaluates cases and advises clients. The training at Villanova emphasized doctrinal analysis and courtroom procedure. His undergraduate study at Penn exposed him to broader analytical methods that still inform his written work. Together, those experiences shape how his office prepares briefs, organizes discovery and presents options to clients.
Running Koller Law, LLC means balancing client advocacy with the administrative demands of a practice. He oversees a team that handles research, client communications and case logistics. The firm operates in the Philadelphia region and serves clients whose matters arise in Pennsylvania and New Jersey.
He remains active in the local bar associations and uses those connections to stay current on practice developments and procedural changes. He currently practices at Koller Law, LLC, handling legal matters in Pennsylvania and New Jersey.
