AREAS OF PRACTICE

  • "Jason came advertised as a zealous advocate. I was told that he was a well- regarded former prosecutor in the Hudson Valley with a reputation as a fearless litigator who was always prepared. Suffice it to say, Jason lived up to the hype."

  • "I will always be grateful for the sincere empathy and compassion Jason demonstrated for myself and my family during a critical time in our lives. His relentless pursuit of the best outcome in my case was unparalleled."

  • "When I first needed help, I thought I was going to lose my job. Using his skills, dedication, and through the development of a unique legal strategy, Jason made sure that NEVER happened."

  • "Due to Jason’s hard work and professionalism, my arrest resulted in no criminal record and will have zero impact on my future employment."

  • "In each of the three cases, in three different courts, all of which started as felonies, Jason rejected every single offer made by the DA’s Office, opting instead to challenge the evidence. In each case, he was successful."

If you have a concern or question about a potential case, our team is here to help: in English or Spanish.
