Costello, Brennan, DeVidas, Sasso and Sinclair, P.C.

I do not recommend.

Chris Brennan represented me in my divorce matter. Throughout the representation he explained the process and was very knowledgeable. He made a very difficult situation easier to deal with. In the end, I received a great outcome. I have referred a number of friends and family to Chris for all types of family matters.

Chris Brennan and Anthony Sasso should not be involved in family court matters. In my experience, their handling of my case reflected a misunderstanding of family law practice and the realities of working with experienced counsel and judges. This led to unnecessary delays, missteps in strategy, and prolonged conflict. As a result, my case was negatively impacted for over a year, and I ultimately had to retain different counsel to correct course.

I had the privilege of being represented by Attorney Chris Brennan in a restraining order matter and Attorney Alissa Korwek in a post-divorce matter, and I cannot recommend them highly enough. Both attorneys clearly know what they are doing. They are strategic, realistic, and incredibly effective. They fight hard when it matters, while remaining fair, level-headed, and professional at all times. What I appreciated most is that they focus on getting results without dragging cases out unnecessarily—something I have unfortunately experienced with other attorneys in the past. Their billing is fair, reasonable and transparent, their communication is clear, and they respected both my time and resources. I felt informed, supported, and confident every step of the way. Most importantly, I trust them 100%. If you are looking for attorneys who are competent, efficient, and truly advocate for their clients, I would not hesitate to recommend Chris Brennan and Alissa Korwek.

I am immensely grateful to my defence lawyer Anthony Sasso for the outstanding service and support I received during my divorce proceedings. Going through divorce is not easy but the legal expertise and compassion from him and the chambers gave me profound peace to focus on my job as my legal needs are expertly and thoughtfully taken care of. They kept me informed with every necessary details and allayed my fears whenever they came with their compassionate sense of professionalism. They fought for my best possible outcome with integrity and skill. Without hesitation I recommend them if you are looking for integrity, competence, and absolute commitment to get the job done

I recently worked with Attorney Sasso on my divorce. He was recommended by a long time friend who had worked with Anthony before in the past and had nothing but great things to say about working with him so I knew I didn't had to search very hard for someone to work with. I found him to be very personable and professional. Upon our first meeting, he asked all the right questions to understand my situation which made me feel comfortable and explained what the process would entail and the sequence of events that would follow. I found the response time in answering any concerns I had along the way were answered within 24 hours if not sooner. He kept me informed of all communications with the other side and felt he was proactive in making sure I was prepared for the next steps in the process. I never felt like I was just another case. He is extremely knowledgeable and realistic about what could be the possible outcomes and offered the good and the bad of each. We've all heard before the divorces can get really messy however that was not my experience, I felt he always had a "Let's get this done" attitude which is exactly what I was hoping for. Thank you Anthony for offering your best, I greatly appreciate it.

I hired Chris Brennan to handle my post-judgment matters for my divorce. He was beyond successful at every Court appearance in achieving what I wanted. My ex-wife had hired one attorney after another attorney to file one motion after another. It was beyond brutal! Once I hired Chris all of that stopped as he was able to obtain judgments in my favor, ultimately getting her to back down. I have referred a number of close friends and colleagues to Chris as he is a great attorney. This was no easy case. But Chris got it done. I HIGHLY recommend Chris.

Chris Brennan represented me throughout my very litigious divorce. He gave me great advice throughout the entire process and was by side the entire time. I strongly recommend using Chris if you are in a similar situation.

Chris Brennan represented my daughter in connection with her personal injury case. He did a terrific job for her in filing a lawsuit and aggressively fighting for her. In the end he secured a large verdict for her and we couldn’t be happier with the outcome. I strongly recommend this attorney to anyone who has been injured and needs a good lawyer.

Christopher Brennan represented me in connection with my divorce. He was by my side through the entire process, protected my rights and stood up to my abusive controlling husband in court. I felt protected through the entire process. Chris was always available when I needed to reach him and very responsive. He was smart and aggressive with the other side and very reasonable with my financial situation. He secured a very favourable amount of money for me. I wouldn’t be able to make it without him. I will strongly recommend Chris for any woman that might be in my situation. He is an excellent attorney and great advocate.

Chris Brennan represented me for a divorce. He guided me through the entire process and kept me informed every step of the way. He protected my rights and I was very happy with the result. I would recommend this great attorney to anyone going through this kind of situation.

I had high hopes going into my divorce proceedings with this firm, but unfortunately, my experience is far from satisfactory. The communication was terrible—I as adviced to sign documents that hurt my situation. Meetings were cancelled. I was always blamed for delay. Attorney Alissa Korwek seamed more concerned about need of opposing attorney - accommodating other attorney needs in terms of time/schedule or agreement language. I also felt that my attorney didn’t fully understand my situation or offer sound advice. They seemed disorganized - canceling my meetings due their internal time conflicts. On top of that, the advice I received was not only unhelpful, but it also costing me more in the long run due to poor decisions that were made without considering all of my options. I can't help but feel that better representation would have led to a more favorable result.

I hired attorney Anthony Sasso for assistance with child custody issues and child safety issues I was having with my ex husband who was arrested on DV charges. Attorney Sasso was absent and unresponsive consistently. Which resulted in me still dealing with the same issues I had come to him for help with. I was not satisfied and made this known. I was able to negotiate my balance owed down because of the lack of representation I received. When it came time to make my agreed upon payment amount I was told they have no record of this. I regret my decision to use this firm. My child is the one who’s still not fully protected legally and suffering because of the inability of this firm to deliver on what was promised.

I, unfortunately did not have a good experience with this law firm. Initially, I hired Kieran Costello to represent me in my divorce case. At first, my experience with him was fine, he kept me abreast of developments in my case. He eventually turned my case over to attorney Anthony Sasso and that is when my experiences went downhill. He acted like he did not want anything to do with my case. He did not keep me informed on developments in my case, was not responsive to my emails and phone calls and at times was downright dismissive, acting with disdain and nonchalance. In his interactions with the opposing attorney, he began to believe false, unsubstantiated claims that were made by him and my ex wife regarding me. Instead of speaking to me or asking me questions to find out particulars, it became apparent that he believed their words over mine. To make it worse, he ghosted me on my case close to the time we were to go to court and showed a lack of professionalism and testicular fortitude seeing that he didn't even have the courage to give me an email/text/phone call indicating that he was doing so. I wouldn't recommend doing business with this firm.

I cannot express enough gratitude for the exceptional service provided by Costello, Brennan, DeVidas, Sasso and Sinclair, P.C. throughout my divorce process. From the moment I walked into their office, I felt supported and understood. Anthony Sasso, in particular, has been a beacon of professionalism and expertise. He took the time to understand the intricacies of my case and developed a strategy that protected my financial interests and ensured the best possible outcome for my children. His negotiation skills were top-notch, securing favorable terms without the need for prolonged litigation. Anthony’s support extended beyond just legal representation. He was always available to answer my questions and provided clear, consistent communication, making a difficult time much more manageable. His dedication to my case was evident in every interaction, and his efforts in coordinating with tax attorneys to resolve related issues were invaluable. The entire team at Costello, Brennan, DeVidas, Sasso and Sinclair, P.C. was professional, compassionate, and highly skilled. They made sure all my legal needs were met promptly and efficiently. I highly recommend their services to anyone in need of top-tier legal representation. Thank you, Anthony, and the entire firm for your outstanding work!

Chris Brennan represented me in a recent divorce. I was very happy with his services and the case outcome. I highly recommend Chris and team.

Could not ask for a better experience, given the unpleasant/difficult nature of the situation. If you're going to go through it, at least having representation that is professional, timely, and on top of it gives you one less thing to worry about. Highly recommend.

When dealing with a lawyer I wanted someone personable. I had the pleasure of working with Attorney Sean Plumb. I went through a very difficult divorce and child custody battle. His responsiveness, analytical skills, research and organizational skills were amazing. He always listened to my every concern and he came very prepared for court each time. His knowledge and compassion made such a difference during this life changing time. I highly recommend working with Attorney Plumb you won’t have any regrets. His legal representation restored my faith in the system.
