The Strategic Attorney You Want on Your Side

Leslie is the attorney you want on your side - before she accidentally ends up on the other one. She guided me with confidence through a complex divorce case that involved delicate international aspects and a highly significant deadline. Throughout the entire process, Leslie demonstrated steady, s...trategic thinking that became the framework we relied on at every stage. I felt supported by a professional who deeply understands the complexities on one hand, and knows the system inside out on the other. She knew how to calm me when needed, lead with clarity and confidence, and explain every step with precision. She was available for every question, and gave me a solid foundation to lean on. I truly felt I had someone who could speak up for me in the most accurate, protective, and effective way. I am deeply grateful for Leslie’s guidance, clarity, and protection under these sensitive circumstances.

Professional and caring

Leslie is a tremendous attorney to have in your corner. She is professional, astute and cares about her clients. She worked with me on a difficult custody/support case, providing sound advice and representation throughout. I would highly recommend her to others.

Professional, Responsive, & Experienced

Leslie has represented our family in two different co-parenting conflicts. The first was a contested parenting plan modification and the second time she defended me against a contempt charge. In the first proceeding, she got me more time with my daughter and many other small parenting plan changes... that have made a huge positive impact in our family. This was no easy feat as this happened during COVID and everything took longer and was more difficult than it should have been. Leslie also represented me during the day and a half mediation that this deal required and we avoided having to go to court. She fought so hard for us and was responsive and encouraging to us the whole way. The second time she represented me, I was defending myself against a contempt charge. We won that case and I could not have been more impressed with the case she made for me. She was calm and collected, professional, and prepared. In the months leading up, she went over every option and possible path forward, always mindful of how best to keep our costs low. Unfortunately, we will likely find ourselves in need of her service in the future and there is no question that she would be our first choice. Leslie is the best!
