Client Testimonial

“Michelle Sullivan has been my family law attorney for the last 18 years. Michelle has handled both pre- and post-judgement issues for me. She aggressively advocates my position while providing cogent, incisive advice and counsel. Michelle has detailed knowledge of military family law issues and can translate and apply that knowledge to California family law. Honest and realistic in her evaluation of the situation, Michelle always provides you with the pertinent information so that you can make a fully informed decision on how to proceed with your case. Highly recommended for any family law case dealing with military issues. Michelle and her firm are my 'turn to' attorneys.”

"Over the last couple of years, continuing child custody issues have required the services of attorneys on numerous occasions.  While we have been generally satisfied with the representation we have received, we have always thought the industry could use improvements in general office organization and client service.  What a wonderful difference we have seen in your office and practice!  Your office is well organized and a great example of efficiency and excellent client service."

“Thank you so much for holding our hands through this adoption process.  We are lucky that we had such a skilled team to help us win such a rough case.  The adoption day went wonderful and we can start anew! Thank you for everything!”

"I would strongly recommend mediation in general to all parties beginning the divorce process, and would recommend Michelle Sullivan specifically to all who are in the greater San Diego area.  She not only saved us tens of thousands in legal fees over a traditional divorce, she kept us from becoming adversaries.

As my husband of two decades and I accepted that our marriage was inevitably ending, we agreed that for the sake of the children, and our remaining assets, we did not want the typically contentious process often created by hiring two opposing attorneys.  We realized, however, that as a couple whose greatest struggles had revolved around spending decisions, communication and decision-making processes, we were perhaps not excellent candidates for mediation.

Despite our well-established patterns of bickering and jockeying for control in these most important of areas, Michelle Sullivan has done a wonderful job keeping us focused on our long term goals and helping us compromise.  She has alternately corrected and supported each of us as was necessary, and has proved herself a skilled negotiator and a woman of compassion. Even more importantly, Michelle's involvement kept us operating as a team throughout the settlement process.  This allowed us to continue to co-parent effectively as well... a reality I cannot imagine would have been the case had we each hired our own attorney. We are grateful."
