She helped me get it done quickly with as little drama as possible. I am so thankful for her efficient services during one of the most difficult times in my life.”

people“I hired Mrs. Mongiello’s firm to handle my divorce settlement. It wasn’t a complicated affair because my ex-husband and I had come to an agreement before contacting the lawyer.

She is young and dedicated.”  ~Originally Posted on Avvo Posted by  Client Erin on December 7, 2016
