Outstanding lawyer
I was referred to Joni by a friend at a time when I desperately needed to handle a really bad situation at work. Joni is a first class attorney - she was extremely responsive & knowledgeable, and handled my case very strategically. Her advice was always on point, emotion-free, and smart. I hope I'd never need to hire an employment attorney ever again. However, if you are reading these reviews in search for an attorney - you could stop looking. She's the one you want in your corner when things get turned upside down.

Great Experience
I was referred to Joni by someone when I came across a frusterating and difficult situation with a former employer. She was very understanding throughout the ordeal but remained solid as a rock when it came to my rights. She was able to solidify a great severance for me. Joni is highly knowledgeable, professional, timely, compassionate and was always accessible. I highly recommend Joni.

Successful Negotiator
My situation required negotiating of severance plus client retention. It was handled very well. Joni had to be relentless in getting what was needed and she was successful.

Fast, informative response
I found Joni through a friend and could not have been more pleased with her response. I was looking for guidance on my options within an abusive work environment. Joni calmly talked me through the law, what my options might be and was very direct about her fees so I could make a thoughtfully informed decision about how to proceed. Even after I was able to clear up the situation on my own, she still provided follow up advice. I would definitely seek her council in the future if necessary.

Calm, strategic and thoroughly knowledgeable
When Ms. Kletter took on my employment-related case, she was quick to understand the facts and equally quick to establish expectations. She subsequently spelled out my options to tackle both my financial wants and emotional/mental redress. Joni is friendly, patient and strategic. She can also be assertive/responsive when strategically necessary—such as when an adversary needs to be prompted into action. On a day-to-day basis, Ms. Kletter has been quite helpful and timely about answering questions or allaying concerns I might have about my case's direction. She is great at establishing rapport, and has maintained a positive and friendly tone in conversing with the adversary, which has helped tremendously. As for bottom line matters, Ms. Kletter deserves high praise for a good strategy that produced a settlement that significantly exceeded my expectation.These are all things I would expect from best-in-class counsel, and I accordingly would absolutely recommend her.

Responsive and knowledgeable, not to mention an EXCEPTIONAL lawyer and person!
Joni Kletter treated my case (although not nearly one of her larger cases) as a top priority. She kept me informed of all updates via email and called me intermittently to review. She was almost always available when I phoned and if I needed to leave a message for her to call me she called back within the hour. Emails were promptly answered and she explained everything to me (someone with zero legal knowledge) with great detail and answered any and all questions intelligently but always in a way I could understand. Throughout the duration of my case I knew I was being represented by someone with exceptional knowledge and skill. I will admit I was a bit apprehensive at first but the minute I sat down with Joni I trusted her 110% and highly recommend her as she is an exceptional lawyer and person.

Sharp, Intuitive, Compassionate Lawyer
Joni Kletter is an incredible lawyer. She knows when to act boldly, she knows when to wait patiently. Each recommendation she gave me was brilliant and the right call. Because of her sharp, careful, experienced actions, I had the best possible outcome to a very difficult situation. And through it all, Joni remained an empathic, motivating advisor on a painful road. I never needed a lawyer prior to this experience, and Joni embodied all that one could possibly want in an attorney-intelligence, confidence, competence, and compassion. Joni was in constant communication with me and responded immediately to any email or phonecall. She was respectful of the sensitivity and urgency of my circumstances. Having her in my corner was reassuring and powerful. She delivered amazing results.

Joni Kletter is a quality lawyer and I highly recommend her legal services
I highly recommend Joni Kletter as a legal advisor on employment benefits issues. I was referred to her by a peer professional to advise on the negotiation of a severance agreement that I needed to finalize for myself under a tight deadline. Through responsive phone calls and emails over the course of a week, Joni gave me the solid legal advice I needed to make a sound decision on the terms of the severance being offerred to me. Joni's counsel included not only legal analysis of the document I need to sign but a healthy dose real-world business and financial expectations to consider in making my tactical moves during the negotiations. I could not have asked for better counsel.

Highly Reccomend Joni Kletter
I highly recommend Joni Kletter. I have worked with her a couple of times over the years. Ms. Kletter has not just a fine understanding of the law, but also an excellent understanding of the realities of the work place, and what can be accomplished. In this most recent situation, a nuanced approach was what was required for an excellent outcome, and that is what was achieved. I am highly grateful to her.

A Great Lawyer and Amazingly Patient
Having come out of a horrible work experience, Joni was incredibly patient and helped me to communicate with my previous employers and achieve a great settlement for me. I was not at my emotional best because my working experience had been incredibly hard and I was worried about my future. Joni was not only able to negotiate my legal rights but she was also a tremendously patient person. Her patience was especially valuable since my previous employer was extremely difficult to deal with. I feel as though my situation was not only in the hands of a great lawyer, with a great firm backing her up, but also in the hands of a compassionate person who was working for the best results on my behalf. I would highly recommend hiring Joni Kletter .

An Amazing Attorney
I hired Ms. Kletter to resolve a dispute with my employer that I had not been able to settle on my own. Even though I retained her after I had attempted to negotiate a settlement on my own, she came in and did an amazing job. She was even able to get me a better settlement than I initially requested. She was professional at all times and kept me informed at every point in the process. I was very impressed with her ability to take on my matter on short notice, and the positive results she achieved given the circumstances of my case. I will definitely recommend Ms. Kletter to my peers.

The best possible experience I could have had. Joni was very helpful, honest and professional every step of the way. I was very happy with the service provided and appreciated her excellent legal mind and honesty. Simply superb.

Hardworking, Honest and Passionate about Your Case
I came to Joni after going through a nasty employment issue. Joni listened to me and patiently explained all of my options from a legal perspective. I never felt like she was pushing me in one direction or another - just giving me the facts so that I could make informed decisions with her guidance. She knows employment law through and through, and because of her expertise, we settled our case VERY quickly out of court. She is awesome and a true force to be reckoned with - you absolutely want Joni on your side. While I hope to never go through something like this again, if it were to happen, Joni would be the first person I would call.

Great lawyer
Joni worked with me for three years on my case. She was with me every step of the way. She guided me through a very difficult and confusing legal process and could be counted on at any time. You feel like you are her only client, even though you aren't.

Experienced, Empathetic, Encouraging
When I came to her in a time of need she was the only lawyer that took the time to listen to my story. As we talked she helped me understand what options the law could provide. From this moment on I felt taken care of, knowing she had my best interest at heart. She kept me informed at all times and anticipated very accurately how the process would evolve. She knows when to push and when to wait. This to me is the most important skill of a talented lawyer. I am very happy with the outcome of my work with Joni.
