We handle discrimination cases asserting gender, national origin, race, skin color, age, religion, familial status, disability, retaliation or sexual orientation. You are protected by City, State and Federal Laws. I was a mediator for the EEOC.

Expungement 5%

We routinely handle the negotiation of U-5s, and we file FINRA Arbitrations to expunge a negative, defamatory, incomplete or false U-5 filing. The U-5 is a minefield, often branding employees as bad actors, impairing one's re-employment prospects.

Highly recommend: Effective and Highly Efficient

My lawyer was effective and highly efficient throughout the process. One of my biggest fears was having to regularly see the abuser and even a more hostile environment while the case was handled. Prior to Mr Sack’s involvement, individual regularly aggressively screamed at me and intimidated me (6’...4 tall man banging books on the desk while aggressively screaming at me, 5’2 woman, because I enquired about internal opportunities), constant sexist comments on my voice, clothes and personal life, “jokes” about using “mothers room” after returning from maternity leave in front of everyone (toxic trading floor) or email. However, as soon as Mr Sack got involved, the harassment and intimidations almost immediately stopped (that alone was such a relief). Work accommodations were quickly made; I didn’t have to see or hear the individual, except via email and only work-related requests. When it came time to leave, the process was seamless—I left without any awkwardness, confrontation or regret. Most importantly, the matter was resolved with fair compensation. I’m deeply grateful for my lawyer’s professionalism, guidance, and support during such a challenging and hostile situation.

Professional and genuine

I sought Jonathan's representation when my employer let me go after years of discrimination. He was professional, persistent, and genuinely cared about my situation. He quickly negotiated a severance package more than four times what was initially offered to me. I would certainly recommend him.

The best

Jonathan helped me every step of the way to negotiate a separation agreement with my former employee. The issues at hand were gender discrimination and sexual harassment and I'm so thankful for his counsel.

Client

I am a woman in the financial industry with decades of experience, a stellar reputation who was wrongfully terminated. I hired my lawyer, Jonathan Sack, to represent me in a mediation with this employer and it is my pleasure to write this review. Jonathan Sack and his team's ability to combat a for...midable opponent was astounding. I cannot imagine there is any firm better equipped to accomplish what he did for me. His professionalism enabled him to fight on the level of the opponent without compromising his ethics. His integrity through all of this never wavered from being a perfect example of knowing precisely the difference between right and wrong. Despite the challenges of having to deal with some difficult opponents, Jonathan's character as a human being is amazing and he takes tremendous pride in what he does. In my case, he rose above and beyond the call of duty to achieve the best possible outcome. I would not hesitate for a moment to recommend Jonathan Sack to anyone, particularly if it involves a woman who finds herself in an unfair and unjust predicament that has nothing to do with her competency as an employee but instead, her gender.

Managing Director

If you need an employment lawyer Jonathan is the ONLY lawyer to call. He is the perfect balance of absolutely straight forward, fights like heck for you and he truly cares. I would recommend him to anyone with a discrimination or employment case. Calling him was the smartest thing I did when I felt I... needed to consult with a lawyer. He cares until the end and beyond as he keeps your case on course to make things right.

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
