    "Her professionalism and depth of knowledge are truly impressive"
    Lynn Poster-Zimmerman is uniquely well suited for the profession that she has chosen! Her professionalism and depth of knowledge are truly impressive, but her warmth and caring are the "icing on the cake"! One very special experience exemplifies Lynn's commitment to her clients. We were in the process of updating our wills with Lynn, when the pandemic took hold. Lynn understood the urgency of completing this process. At this time when in-office meetings were prohibited, Lynn actually arranged an outdoor meeting for our mutual safety, and enlisted colleagues to be our witnesses. Lynn has been there for us for our legal needs; wills, trusts, pre-nups, power of attorney, etc. and we know that she is the one that we can count on when we need her in the future.

    "Ms. Lynn and her team are professionals."
    I am very lucky and blessed for having Ms. Lynn, as she’s the best lawyer. She always protects you and never gives you a chance to give up. There was 8 petition against me and thanks to her all of them were dismissed. Ms. Lynn and her team are professionals. Court day has never been stressful when during trial your interests are well protected by Ms. Lynn.

    "What a great relief it is to know that your Attorney always acts in your best interest and advices you of the most effective strategy pursuing your case."
    I found myself in such desperate situation in the Summer of 2018, when I was faced with a tough decision of filing for emergency custody over my grandson. From my very first meeting with Lynn Poster-Zimmerman I knew I am in good hands. It was not just an intuitive feeling based on excellent first impression. Ms. Zimmerman came highly recommended to me by a professional counselor and to this very day I am grateful for this recommendation. Lynn’s passion for Law and her deep knowledge of the subject matter amazes me to this very day. Not only that, Lynn is one of the very few Attorneys who feels true compassion for her clients and it shows in so many capacities: in a way you feel as if you gained wonderful, carrying friend whose presence in you life makes the burden of your situation easier to bare. I do not recall a single time where Lynn did not return my phone call or e-mail. Ms. Zimmerman is also an excellent listener with what I can only describe as an uncanny memory. I recall so many times when I completely fell apart during Custody trial and one thing I remember clearly is my Attorney, Lynn Poster-Zimmerman, always comforting me and reminding me to remain strong. Her knowledge of the Law is incomparable. It is actually beautiful to watch Lynn work the Court room. Great Attorneys know their area of practice: this knowledge comes from experience and from excellent education. In Lynn’s case it comes from both, moreover Ms. Zimmerman is in constant state of keeping herself updated on any possible changes in the Law, trials and verdicts which ultimately influence and change in the way Law is applied in certain cases. Our Custody Trial is nearing the end and through the entire Trial, I never once regretted having Lynn Poster-Zimmerman on my side. I would highly recommend Lynn’s services to anyone. She is an invaluable resource and an Attorney of high integrity.

    "Lynn Poster-Zimmerman has been a GREAT ASSET!"
    Lynn Poster-Zimmerman came to me on recommendation and she has worked hard for me from the beginning. I have a great respect for her and the work that she does. Due to ex-husband being uncooperative, she has made sure to have full documentation of it all. She has put in many hours by getting to know me and my case. She has stood by my side and represented me in my divorce proceedings with vigilance!! I COULD NOT HAVE ASKED FOR A BETTER LAWYER! I applaud Lynn for her service and diligent work!!!
