Nick Callas spent over a half hour explaining things to me that my last attorney failed to tell me. I have some appointments to make but as soon as I’m done Nick will be my first call! He was informative, knowledgeable, and understanding. Plus he was easy to talk to.


Trish Marsello – Client

I needed a second opinion on my disability approval. I’d been approved, but not for retroactive payments. I called the Callas Law Firm and spoke directly with Mr. Callas, which was refreshing. He advised me beyond my expectations in a friendly, kind and respectful manner. I highly recommend counsel like him and his firm. Thank you, Mr. Callas.

Eve Morales – Client

Mr. Callas was a tremendous asset in my workers compensation case. He was always on top of everything involved in my case. He doesn’t let the otherside sit on their hands and beat around the bush. He gets the job done.
