A word from our clients

The staff at Cushnie & McMahon made us comfortable and are very kind. I always feel like I am working with trusted individuals. I would recommend them to anyone needing a lawyer. We dealt with Paul, but his partner came to the hospital to start things rolling. They provide very fair, honest, and direct services.


I am a fairly intelligent person but law I tend to find very convoluted. Cushnie and McMahon were very good about thoroughly explaining things to me and they did it in a way that I could relate to and understand.

Joan Weber

The lawyers at Cushnie and McMahon always made sure we were comfortable. It was great working with a kind individual that you could trust.

Maria Rivera

Great lawyer! Honest, trustworthy. Took my case after another lawyer dropped me and said I did not have a case. Mr. Cushnie went above and beyond my expectations. Already recommended him to a friend. He is an A++ lawyer

Neil Laporte

I was made to feel as if mine was the only case they were handling due to the time they take to explain detail by detail of what one cans expect. I know my case was not “huge” but they treat all cases the same…with empathy to their client and a true interest for one’s well-being. I cannot say enough of Cushnie & McMahon and at times “Thank You” is not enough. I recommend this law firm very highly & if my words can hep someone needing an attorney…I hope this has helped, as I have written with sincerity and true appreciation!

Lily Sanford
