Zeisler PLLC, located in mid-town Manhattan, is a team of highly-accomplished and experienced attorneys with large firm training and experience practicing in several areas including litigation, corporate, employment and employee benefits, trademark, copyright, patent, nonprofit, real estate and taxation.

We advise domestic and foreign clients, from start-ups to established public companies, on a wide range of complex business, transactional and litigation matters. We strive to provide premium service to our clients in a cost-effective manner.


Zeisler attorneys partner with other United States and international law firms as needed to ensure that their clients always receive the best possible advice.  For litigation matters, we regularly appear in courts across the United States, and in the area of alternative dispute resolution (ADR), we handle arbitrations and mediations in various forums such as the AAA, JAMS and FINRA.

The attorneys at Zeisler build a deep understanding of their clients’ needs and aim to become trusted advisors in their areas of expertise.  Zeisler attorneys also serve as outside “in-house” counsel to a number of their business clients, given their long-standing relationships and knowledge of the client’s operations and objectives.  We take pride in our client relationships.
