About Mark & Kleinfeldt

New Jersey Employment Law Attorneys

New Jersey employees facing workplace violations deserve attorneys who are fighting exclusively for them. That is who we are — and the only kind of case we take.

Who We Are

Mark & Kleinfeldt was built on a single principle: if you do right by people, you will do well. The firm has always represented employees only, in employment law only. That focus is intentional — it shapes how cases are evaluated, how clients are treated, and how the attorneys approach every matter that walks through the door.

Jamison M. Mark

"I live and practice law by the theory that if you do right by people, you will do well.

I treat my clients as I would my own family."

– Jamison Mark, Partner

The attorneys here do not take cases just to settle them. They take cases they believe in and fight for results that are fair. That means telling clients honestly whether their case is worth pursuing, not promising outcomes that are unlikely, and staying in the fight when it matters most. Employment law is all this firm does — and that kind of focus changes what is possible for every client.

Why We Focus on Employment Law and Only Employment Law

Every case the firm handles builds on the last. The attorneys at Mark | Kleinfeldt know how employers and their lawyers think, because they have spent years learning exactly how employment cases are won and lost. That knowledge only comes from doing nothing else.

Adam-Mark – 1

Representing employees only means there is no conflict of interest and no divided loyalty. The firm is always on the same side: the employee's side. When an employer's lawyer knows they are sitting across the table from attorneys who do this exclusively and are prepared to go to trial, that changes what gets offered.

Mark – 1

What the firm has built as a result is a track record of results in exactly the area of law where the client needs help: discrimination, harassment, wrongful termination, whistleblower claims, wage violations, and employment contracts. No unrelated practice areas. No distraction. Just employment law.

How We Work With Clients

Honest Case Assessments Upfront

Honest Case Assessments from the start

Most firms tell you what you want to hear. This one tells you what you need to know. As Jamison has said: "I'll tell them upfront whether I believe their case is worth pursuing or whether another course of action could achieve better results. It's not about taking more cases; it's about helping more people." That kind of honesty is the starting point for every client relationship here.

About Page - Know Where Things Stand

You always know where things stand

Clients work directly with the attorneys handling their case, not assistants, not rotating staff. Communication is consistent and clear throughout. As Jamison has put it: "I walk clients through case details, timelines, and strategic options, providing an honest and risk-calibrated evaluation up front." Clients have specifically noted this: they always felt informed and never left wondering.

About - People Not Cases

People, not case files

The attorneys here take these cases personally because they care about the people behind them. Jamison coaches youth sports, serves on the YMCA and Soccer Club boards, and has built a practice around the belief that if you do right by people, you will do well. Clients feel that, and they say so.
