Gabler's areas of expertise are employment law, civil law and passenger rights. Lawyer Gabler laid the foundation stone for this specialization during his studies and covered the main areas of employment law and corporate law.
The specialization in the field of passenger rights developed from his private passion for travel. In 2017 Gabler then fulfilled his wish to work as an independent lawyer. Together with his colleague Hendel, Gabler & Gabel founded the law firm Gabler & Hendel Rechtsanwälte in Regensburg and Landshut.
