David Koller, Esq.

Meet Attorney David Koller, Philadelphia Employment Lawyer

When it comes to my clients’ cases, I try to be tough, fair, and determined at the same time, while also being collegial with my adversaries.

Every day, I strive to treat my profession and clients with dignity and respect. I find that it helps position our clients to get better results.

For over two decades, I have represented employees with a wide range of employment law matters including sexual harassment, wrongful termination, workplace discrimination and more.

My Passion - Helping Mistreated Employees

I take pride in helping people who have been wronged – those who need a voice and a partner to defend or pursue their rights. I suffered a stroke at the age of 33. I am a survivor, and am here to advocate for you, my clients – regardless of background, race, national origin, religion, gender, sexual orientation or disability.

Types of Employment Law Cases

I am licensed to practice Employment Law in Pennsylvania and New Jersey, have appeared before the state and federal courts in the Eastern, Middle and Western Districts of Pennsylvania and the District of New Jersey, and have also argued before the 3rd U.S. Circuit Court of Appeals.

In the workplace, the rights of far too many employees are violated. I handle and litigate a wide range of matters – many of which are contingency fee, which means there are no upfront costs to the client.

Education and Legal Background

In 1999, I graduated from the University of Pennsylvania. After Penn, I attended Villanova Law School where I served as president of the student body. In 2002, I received my law degree and was given the honor of being a commencement speaker at my law school graduation ceremony.

After law school, I worked at various law firms in the area. I was blessed to have an opportunity to represent one of the world’s largest employers, gaining insight into many different aspects of employment law.

Reputation in Our Community

I am from the Philadelphia area and have never left. I handle cases all across Pennsylvania and New Jersey. I travel to clients, and do whatever it takes to establish a strong relationship between lawyer and client.

I have a reputation for excellence and have been selected by my peers as a “Pennsylvania Super Lawyer – Rising Star,” a distinction given to less than 3 percent of lawyers in Pennsylvania under the age of 40. I have also been selected as a Pennsylvania Super Lawyer.

I have lectured at various law schools, hospitals, businesses, and institutions on various aspects of employment law. I am regularly quoted in the media including The Legal Intelligencer, the nation’s oldest legal publication.

(March 14, 2021)
A Pa. mom says her boss forced her out of her job during the pandemic. She sued.

It’s close to impossible for many parents to work and also care for young children, said Philadelphia employment lawyer David Koller, who represents Delaney.

The Families First Coronavirus Response Act, effective March 2020, required employers to provide paid sick leave and paid leave to care for children whose schools had closed due to the pandemic. Employees who suffered demotions, lost pay, terminations or other negative consequences at work may be able to make a claim under the Families First Coronavirus Response Act.
