I hired Dianne as my divorce attorney. First of all, she is one of the very few attorneys who answers her phone and calls you back right away, I mean 6AM kind of right away:). She is very experienced, confident attorney with a lot of knowledge. She advised me on some details and worked by my side to protect my interests. She cares about her clients and by hiring her, I got an attorney whom I actually could trust. The feeling that I am protected and nothing was going to be missed made my stress levels lower and made me feel more confident during this stressful and emotional time. The case was settled; I have my house, my vehicle, and my kids - everything I asked for.

I highly recommend the services of Ms. Sullivan as a competant, ethical and results driven attorney. From our initial meeting throughout the legal proceeding; Ms. Sullivan represented my best interests under the guidleines of the law and that of which we deemed fair and reasonable considerations. Her knowledge of the law and judicial process allowed me, a novice in divorce activity, to make proper decisions for my family; as well as, how those decisions would impact my future. Going through a legal process of any type is extreamely stressful. As is the case of divorce; compounded by emotions which can cloud proper judgement. Selecting an experieced lawyer can make the difference on how those decision impact the rest of your life. My case is now closed; but in reflection, I know the decisions made were seldom simple, but always 100% correct. I have Ms. Sullivan to thank for these results.

I retained Dianne Sullivan a year ago for my Filter Law case. Dianne was the second attorney that I had retained in my on going Family Law case. Dianne was so understanding and on top of everything, that I was able to release her soon after my hearing date. Since that time, she has been there for me with any further questions or concerns that I have about issues that have arisen after the fact. If you want or need a knowledgeable Family Law attorney, Dianne Sullivan is my first choice and will be from here on out.

Dianne represented me in a criminal case where I was unjustly charged with custodial interference. She lobbied hard on my behalf and got my case dismissed. Due to my profession, a conviction would have resulted in me losing my job. I could not be happier with her work on my case.

Hiring Dianne was the best decision I could have made in my divorce case. She truly cares about her clients, and worked hard to get me the best possible outcome. I've recommended her to several friends and family members, all who has similar experiences with her. Even her staff members are kind and know their stuff. I highly recommend her if you need someone experienced and no nonsense.

Dianne was a tremendous help to me in my case. I was a victim of years of domestic abuse, and no one seemed to take that seriously, especially the Court. At trial, Dianne fought hard for me and my son, and helped me win sole custody. If you're are looking for someone knowledgeable, who actually cares about you, and will fight hard, call Dianne.

I would recommend Dianne to anyone struggling with child custody issues. Dianne is aggressive, informed, and caring. Both Diane and her paralegal Marti were responsive and kept me in the loop, even though at times I probably seemed a bit over bearing. It takes a special kind of person to be a family law attorney, and Dianne is great.
