This lawyer was disciplined by a state licensing authority in 2022.
Suspension issued in NJ, 2022
updated on 08/22/2025Suspension means an attorney lost his or her license to practice law for a period of time. The attorney typically returns to practicing law when the suspension expires.
“A reprimand was issued due to a misunderstanding involving parking tickets on a friend’s vehicle I had temporarily used; although I paid my friend for the fines, procedural issues arose because I was not the registered owner, and the court held me responsible despite my good-faith effort to resolve the matter.”
Reprimanded issued in NJ, 2020
updated on 08/22/2025This means the attorney did something wrong, but the Bar did not suspend the lawyer. Typically in this case the lawyer's poor behavior is exposed to the public in hopes that he or she will not repeat the behavior.
“The reprimand was based solely on not having a written contract in a pro bono case, as I did not believe a formal agreement was required when offering free legal assistance.”
Censure issued in NJ, 2017
updated on 08/22/2025This means the attorney did something wrong, but the State did not suspend the lawyer. Typically in this case, the lawyer's poor behavior is exposed to the public in hopes that he or she will not repeat the behavior.
“While caring for my dying mother, I submitted a rushed expungement in a difficult case involving a mentally impaired client; although the outcome was successful, a complaint was later filed due to the filing’s quality, which led to a reprimand. I then provided a full refund to the client.”
Reprimanded issued in NJ, 2012
updated on 08/22/2025This means the attorney did something wrong, but the Bar did not suspend the lawyer. Typically in this case the lawyer's poor behavior is exposed to the public in hopes that he or she will not repeat the behavior.
“In a rare case, an interpreter—unknown to me at the time—provided false testimony, which contributed to my reprimand and mistrial; I’ve handled over 14,000 cases with integrity and success, and I remain committed to delivering strong, ethical representation.”
