My experience with Diana Sladen of Sladen & Costigan Family Law Attorneys was nothing short of outstanding. The firm handled my divorce with the utmost professionalism and care. If you’re looking for a family law attorney who is passionate about her job, knowledgeable, sincere, and a go-getter, I recommend Diana Sladen. Additionally, the paralegal staff was friendly, courteous, and prompt in their responses, which made the whole stressful process much more bearable. The entire team put my mind at ease during a very emotional time in my life. I am profoundly grateful for their services, and highly recommend Diana and her team at Sladen & Costigan to anyone facing similar circumstances.

Let me preface this by saying I have a strong distaste to attorneys, but understand their value in our society. I hired Atty Sladen several years ago and she was a great attorney then. As time went on, I found myself in need of her services again. I expected her to be lackadaisical and laissez-faire since she had represented me several times prior. How wrong I was. She was just as committed, just as tenacious as our first meeting. She thoroughly answered every question I had, gave me encouragement, checked in on me to make sure I was ok. In the court room she's amazing to watch; no bologna. She is polite but fierce and handles herself with confidence and grace. I have referred no less than 6 of my friends to her and they were all pleased with her services. Highly recommend Attorney Sladen for all of your family issues. I'd be so lost without her. Thank you for everything.

Awful experience, was only able to make an impact when the other party had no representation. Once other party took on representation, they were affraid to fight against the other party. When it came to explaining to the stuff judge and the judge made remarks or comments back, they were affraid to get involved with the judge. They are not in the best interest for you, just the ole mighty dollar. Stay away!!!

Diana is an amazing lawyer and absolutely does an outstanding job. Great communication and explaining everything in depth that you may need better clarification about. My divorce and custody agreement were handled with such care. Highly recommend to anyone searching for a great family law firm.

I was represented by Caitlin Costigan and Diana Sladen on my divorce case. We had agreed on assets but went to trial on children custody. I would not recommend this law firm on any custody case for men. They are not experienced at fighting children custody and reducing child support. Caitlin & Diana both worked on my case and I lost my trial and my ex moved the kids to CA. They will not tell you that your chances are not good at gaining custody but they will encourage to fight for custody. I would recommend doing research on the case laws in MA about custody and children removals to another state. I spent more than 70K on the case and we lost at the end. I would not recommend this law firm to battle for custody.

Diana is a kind lawyer and calming presence to clients like us, but tenacious to those she was representing us against. I have had several moments of stress throughout our case and each time she said that it was her job to be the worrier, that she would take care of it - and she did. She is great with our kids too. I would recommend her to any family or any "mama bear" type in search of advocacy.

Attorney Sladen is the best. She takes the time to understand all the facts of the case and truly has her clients best interest in mind at all times. Her team kept me updated throughout the whole length of my case. Even in the crazy time were the world is all online she still was able to deliver top notch service! I highly recommend her!
