George's Story

"I was in a car accident and had surgery on my foot, which led to chronic pain from CRPS. Nick Mastrangelo handled my case, and even though the insurance companies fought us the whole way, I received a great settlement right before trial. It gave me the security I needed to move on with my life. Great lawyers and great people. Highly recommend!"

"While commuting to work, I suffered serious injuries in a car accident. I contacted the Mastrangelo Law Office, and they immediately started working on my case. Nick kept me informed every step of the way and answered all my questions. He got me a settlement that far exceeded my expectations. Their personal service and outstanding results earn 5 stars from me!"

"I was injured by a hit-and-run driver while on the job. Nick and Ed Mastrangelo filed an uninsured motorist claim with my employer’s auto insurance. When the insurance company didn’t make a fair offer, the case went to arbitration. Nick and Ed did an amazing job preparing and presenting it. I ended up with an award that was more than the insurance coverage and 125 times the pre-arbitration offer. If you or someone you know needs a personal injury lawyer, these are the guys to call."

“I turned to Mastrangelo Law Offices when my son was severely injured in a car accident. I’m deeply grateful for the compassion, expertise, and guidance Nick & Ed Mastrangelo provided to my family as we navigated the complex legal process that follows a serious injury. This occurred during the pandemic, adding immense stress since our son was hospitalized and we couldn’t be with him in person due to COVID restrictions. Their support made a difficult time more manageable."
