I highly recommend John Calcagni and his team. My daughter attends college in RI and we live in NY. She found herself in trouble and was arrested on a Disorderly Conduct matter. Our good friend is an attorney in NY and when we realized he could not represent us in RI he found a colleague who highly recommended John. From the first conversation with John, who responded to my initial message immediately, I knew we would be in good hands. He answered all questions and explained the process in as much detail as needed. He was very confident that he would get the charges dismissed. He worked closely with my daughter (his client) while keeping in touch with us, the parents. John was always attainable to us via email, text or phone call and took his time to be sure we understood each step of the case. John delivered the outcome he promised and exactly what we were looking for, we couldn't be more pleased. I would not hesitate to recommend him and (god forbid) I need assistance with the law in RI again, he would be the first call I make!! Thanks John for everything you did for our daughter!!!

I don’t know where to begin! When I first met with John, I immediately felt like I was in good hands. He is charismatic, funny and really takes the time to get to know you and get a feel for your case. He was very detail oriented and thorough and worked with me for almost two years. Through this exhausting and stressful process, he made me feel comfortable and made sure I understood what was going on every step of the way. I am so thankful I went with John and would absolutely, without a doubt recommend him to anyone who needs more

I'm an active duty soldier and I got a DUI. I deserved the penalties and reprimands but I did not deserve to loose everything. When I was notified that I would be facing a QMP board for separation I knew I had to do all I could to fight back against it for myself and for my family. I am extremely grateful for John and his team. I had no idea about the list of standards I was up against that the board would use to determine weather or not I could keep my job and continue to support my family. Mr. Calcagni systematically itemized and proved beyond a doubt that I met and or exceeded each standard giving the board a clear picture that I still hold value to the Army. He took my personal side and my professional side along with all the legal points and drafted a rebuttal that saved my career. Had I attempted to go against the board on my own I would have surely been denied. Not because I deserved it, but because it is a battle that soldiers are not equipped to deal with on their own and the Army provides zero support. It's terrifying to think back about all that I was up against that I didn't even know about. John and his team come highly recommended and I can't thank them enough for leveling the playing field and placing the control of my career back into my hands. My family and I are forever more
