What Our Clients Say

"Nick Mastrangelo and his firm have represented members of my family who were involved in vehicle accidents for over 20 years. In my case, involving my own motorcycle in a collision with another vehicle, he was able to prepare, plan, and get us to the best legal and financial outcome in a short period of time."

Jason A.

“I was hit by a car while walking in a crosswalk and suffered serious injuries. Nick Mastrangelo handled my case and was able to get the driver’s insurance company to pay the entire policy limit. He also was able to get my medical bills cut by more than 60%. The whole office is attentive and treats you like family. I would highly recommend Mastrangelo Law Offices for any of your personal injury needs!!"

Lorena P.

"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."
