Reasonably priced & extremely dedicated
Single mom here, came to see John Cossidente and retained him after my 1st consultation. My bill was nowhere near what I thought it would be, he fought hard for my boy and I. I have full custody and got everything I asked for, he won EVERY court date we had and even got me a little extra. John is a huge advocate for children, he knows his stuff for sure, I am extremely happy to have chosen him as my lawyer. His staff Eva and Nikki are very good about returning emails and calls, as well as keeping you posted on the status of your case. If you are looking for a lawyer that will fight for you and your children, John Cossidente is you guy. Thank You John and staff, I am extremely grateful for all you have done, I'm so happy this is over.

A law firm with Compassion and Morals
Diana and John are by far on the list for one of the best people I've met. I hired John to handle my visitations case after my previous attorney dragged on for over a year and a half to no avail, charging me an outrageous fees. I can truly say that Diana and John hold compassion and possess morality in such a cut throat industry and I truly appreciate that.

Child Support
John Cossidente is the best in his field. He truly cares and understands the needs of single Moms and the needs of the children. I am a single Mom because my ex basically walked out and left me with three small children and two upside down homes. He fought for what my kids need and deserve. I recommend him as often as I can. He and his paralegal keep it personal yet professional and even though they have many cases they treat you as if you matter. He is kind, attentive and gets the job done without dragging your case on. He understands how hard it is to be a single MOM. Sue

Great Attorney, Great Outcome
Great representation we always knew where we stood on our case. John gave us the feeling that he cared about our family and the outcome. His office is conveniently located. When not dealing with John, Dianne is experienced and informative. All of our calls were returned promptly. Great group to have on your side!

John was a knowledge attorney who laid everything out in plain English for you. He told you both sides to every issue. Diana was integral in keeping me informed. Was a very hard situation and these two made it bearable.

Very professional and efficient lawyer and staff
I thouroughly recommend this lawyer to any one in need of family law assistance. John and Diana worked hand in hand to not only help me with child support and visitation issues, but then go through a relinquishment of parental rights from my ex and an adoption of my son for my husband. Everything went smoothly and they kept me well informed.

Irresponsible and careless
John is a carelss lawyer who misplaces his documents and is unprepared. He is not detail oriented and often forgets the facts in the case. I would not recommend him as a family law lawyer and he has cost me custody of my child.
