Client Testimonials

"Kieran and Megan are exceptional, incredibly sharp, solid, quick, organized, impeccable, dedicated and supportive. They fiercely advocated for me and my son and helped me to win EXACTLY what I wanted and more in terms of custody and divorce settlement orders. Kieran’s knowledge and experience with domestic violence cases is rare and unmatched in the area, and in his field.

Before I met Kieran and Megan, I thought my divorce with my narcissistic abusive ex would be an impossible battle to win. I felt exasperated and scared of my ex and there were many times, throughout the divorce process, when I was ready to give up. However, Kieran and Megan always believed me, validated, supported and reassured me every step of the way. When I was ready to give up, Kieran and Megan kindly reminded me to stay the course, to never give up and to never stop fighting for what is right. As the proceedings continued, Kieran and Megan’s unyielding support, protection, expertise, speediness and effective communication with me, helped me to continue to feel reassured and increasingly confident throughout the divorce process, which culminated in an unprecedented victory at the last day of my trial, a moment I will never forget, when justice prevailed!

As I look back on the experience, I feel that Kieran and Megan carried me through a very dark and tumultuous time in my life with professionalism, grace, humor and ease.

Kieran and Megan, we won! I can’t thank you enough for all that you have done for me and my son. You are truly both angels to me. Thank you, thank you, thank you, thank you! Thanks to you, my son and I now have a bright peaceful future ahead of us to enjoy! I will forever be indebted to you both for the enormous impact you have made on our lives and and I will never forget you."

"Divorce is, almost without exception, a difficult and painful process. I am incredibly grateful to Kieran Costello, Megan Leffard, and everyone at Costello, Brennan, and DeVidas for guiding me through with expertise and compassion. They were professional, reliable, and communicative. I was never left wondering what was happening or why. When I reached out to give or receive information, responses came in a timely manner. I have recommended Kieran to a friend and will continue to recommend Kieran and Costello, Brennan, and DeVidas without hesitation. As my marriage deteriorated, I prayed for a miracle and found one. Many thanks for helping me navigate my way out of my previous situation and into my new life."

"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."

"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."
Jonathan Miranda
"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."

Kate Larson

Tom Goodwin
"I hired Claire DeVidas to represent me in my divorce. It started out very simple, but quickly turned into a way more complicated financial situation than expected. Claire helped me sort through all of the details, made recommendations for appraisals where needed, and helped me get a clear picture of our starting point. Then my (now ex) husband started getting escalated as we were working through all the details. I was walking a fine line between wanting to have a good settlement, not wanting to escalate him to the point of going to trial, and not wanting to take more than I felt was fair. Claire had the perfect balance of empowering me while respecting my wishes. I ended up very happy with my settlement, not having to go to trial, and had an amicable closure with my (ex) husband. I am very grateful to Claire for her expert and caring support, and would highly recommend her to anyone looking for a divorce attorney!"
A. Sarai
"I wanted to thank Claire DeVidas one final time for everything she did for us, for all her help! I don’t think the legal aspect of our divorce process would have gone nearly as smoothly without her guidance and expertise- for this I am very grateful!"
Sebastian S., Weston
"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."
