About Jason B. Grosky, Esq.

Professional Experience

Attorney Grosky spent nearly two decades as a tough prosecutor, trying thousands of cases on behalf of the government. Today, he uses that experience to fight for individuals facing criminal charges. Before founding Grosky Law, Attorney Grosky served as the prosecuting attorney for the Salem (N.H.) Police Department from 2009 to 2024. He prosecuted more than 100 DUI cases annually and appeared in court virtually every day, handling matters ranging from domestic violence, drug offenses, theft, assault, stalking, and serious motor vehicle crimes to felony cases involving robbery, sexual assault, child pornography, and burglary. Attorney Grosky began his career as an Assistant District Attorney with the Essex District Attorney's Office in Lynn, Massachusetts, where he tried numerous jury trials and litigated suppression motions involving firearms, drug trafficking, repeat OUI offenders, and other serious criminal offenses. Having built cases for the prosecution, Attorney Grosky understands how the government investigates, charges, and tries criminal cases—and now puts that insider knowledge to work protecting his clients.

Licensing/Education

Attorney Grosky is licensed to practice in both Massachusetts and New Hampshire and is a graduate of the Massachusetts School of Law. He earned his law degree while attending classes full-time at night and working full-time during the day as a newspaper reporter. Hired by The Eagle-Tribune before graduating from the University of Massachusetts Amherst, his first exposure to the courtroom came not as a lawyer, but as a journalist covering criminal cases—a perspective that sparked the legal career that followed.

Recognitions

His prior accomplishments include receiving the:
  • Pulitzer Prize for breaking news as part of a reporting team covering the deaths of four boys who fell through the ice into the Merrimack River, Lawrence, Mass. Receiving this award led Jason to enroll in law school.
  • Atkinson (NH) Police Citizen of the Year.
  • Salem Police Civilian Employee of the Year.
  • Forty Under 40 award from The Union-Leader newspaper

Community Involvement

Community service has always been a priority for Attorney Grosky. He recently completed his second two-year term as Chairman of the Rockingham County (N.H.) Republican Committee after serving a decade on its executive committee. He also served six years as an Atkinson Selectman, leading the ballot in every election and twice being chosen by his colleagues to serve as Chairman of the Board. His public service also includes the Timberlane Regional School District Budget Committee, where he served as a member, and ex officio service on the Atkinson Planning Board and Budget Committee. Attorney Grosky has coached youth sports for many years, most recently with the Salem Blue Devils and Granite State Elite softball programs. He has also volunteered with the Rotary Club of Greater Salem, the Atkinson Lions Club, and he served on the boards of the Timberlane Tornadoes Junior Football program and Plaistow Community YMCA. A native of the Bradford section of Haverhill, Massachusetts, Attorney Grosky graduated from Haverhill High School in 1994, where he announced basketball games for community television and wrote for the *Brown and Gold* newspaper. He has called Southern New Hampshire home for the past 25 years. He and his wife have three children, two rescue dogs, Beesly and Pepper, and a cat named Ronald Weasley.
  • I had an excellent experience working with Attorney Jason Grosky. He was professional, responsive, and clearly knowledgeable about every aspect of my case. His guidance made a stressful situation much easier, and the outcome exceeded my expectations. I highly recommend Attorney Grosky to anyone in need of skilled legal representation.
