Claire Devidas is a professional, great lawyer and a person with a big heart. She helped me a lot with the issue of temporary custody of my son during a difficult period of my life, helped me resolve all issues with documents, was always in touch, supported me in court and literally saved my family. Huge gratitude and respect.

I recently had the pleasure of working with Linsey A. DeDomenico, Esq. Linsey took over my case after another attorney abandoned me. From day one she stepped right in, cut through the red tape and challenges, navigated my case as if she had been there from the beginning, kept my case on track, and was a strong advocate for me and my family. She is detail oriented making sure every base is covered.
She is patient and worked hard for a positive outcome. Linsey was able to accomplish in mere months what the other attorney could not/had not accomplished in almost a year. She worked tirelessly and maintained a calm, positive and professional demeanor at all times. Thank you, Lindsey.

I had the immense pleasure of working with Kieran Costello & Sean Plumb throughout my divorce process. Divorce is difficult enough on any individual but both Kieran & Sean couldn't have been more professional, knowledgeable & encouraging throughout the process (Kieran's sense of humor kept my spirits up as well)! They were there by my side & kept me updated every step of the way! The entire staff at this office is wonderful. I would HIGHLY recommend their services to anyone going through a difficult/challenging divorce. They will not disappoint!

In a contentious divorce proceeding, I needed a robust litigation team. Costello, Brennan, DeVidas, Sasso and Sinclair was just what I needed. Attorney Kieran Costello, with his in-depth legal knowledge and Attorney Edward "Skip" Sinclair, with both his legal knowledge as well as his financial background, brought the case to a successful conclusion. I would recommend CBDSS to anyone.

Chris Brennan worked on my personal injury case. He took the time to explain the process, the steps required to resolve my case and kept me informed. I had a great deal of confidence in Chris, he resolved my claim to my satisfaction. I highly recommend Chris to anyone looking for legal representation for a personal injury claim.

I first consulted with Kieran Costello, who was humorous but very knowledgeable. He then handed my case to Attorney Mitchell Teta. Attorney Teta has been amazingly helpful and assertive in dealing with my child custody case. He is honest and direct, and continues to help me fight in court for the best interest of my child. I can't thank him enough for all he has done. Highly recommended firm and law office.

I have referred Christopher Brennan to many of my clients. He has successfully closed several Real Estate transactions and has always delivered top notch service. Past clients have also retained Chris for evictions, misc. litigation and divorce with the same positive results. He is a diligent worker and always responds in a timely manner. I have only received positive feedback from my clients and will continue to refer Chris clients in the future.

I want to thank Kieran Costello and his team at Costello, Brennan and DeVidas. Kieran helped me get through the most difficult time in my life. He and his team were always fast to respond to my questions and gave me good advice at a time that when I found it difficult to think straight. He always took the time to explain the process to me. Kieran went out of his way to get the other side to work with us and come to a settlement.
He worked to bring closure and expedite the divorce. I never felt as though I was just an account at his firm. Not only did Costello, Brennan and DeVidas handle all of the issues involved with my divorce, they treated me with kindness, patience and understanding. Kieran truly helped me to get back on my feet and re-start my life. I wouldn't want anyone to have to go though the pain of divorce, but if you find yourself in the same position that I faced, I highly recommend Kieran to help you get through it.

I was injured at work and was out for many months. I reached out to a close friend who gave me the name of a respectable law firm called Costello, Brennan and DeVidas, P.C. He told me to ask for Chris Brennan saying that he's a young, bright gentleman who is well respected and will waste no time in dealing with the adjuster to help me collect the wages that are due to me.
I called and spoke to Chris explaining my situation and he had me come to his office the very next day for a consult. The end result is that Chris delivered for me and he did this in a timely fashion. He not only had the insurance company bring me current money wise but he was also instrumental in helping me obtain the OK for the surgery that I desperately needed. Lets face one important fact here, weather your going through a divorce or you've been injured on the job or otherwise you want to know that the people or person you've hired to represent you in the court room is a competent and savvy individual.
If your unsure as to who could help you in a tight situation that you never asked nor expected to be in and your going to thumb through a phone book to pick a lawyer. Don't, call Costello, Brennan and DeVidas and let them prove to you like they proved to me that they can and will live up to their reputation as a class" A" law firm.
