I am happy to recomend Erin Fay to any one that needs legal help. Erin is an amazing Woman, Lawyer, Mother, Daughter and Friend. I always felt important to her and she kept me informed on what to expect and when to expect it. She is very smart and negotiates with all parties involved so every one ends up pleased with the outcome. I was in a car accident and sustained injuries that left me unable to work for a short time and with many medical bills. Erin helped my family through the most difficult time of my life and I was compensated beyond my expectation. If any one gets the honor of working with Erin I am sure they will be pleased.

Confident, tremendously intelligent, easy to work with lawyer
Erin Fay has handled various legal matters for me over the years, from the simple to the far more complex, and has never failed to do an excellent job, whatever the circumstances. I've always felt comfortable with her expertise and never doubted her abilities to get the best possible results. She's truly a lawyer you can trust to "have your back" for lack of a better word.
