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.

Exceptional Attorney with an Incredible Team

Many people who knew I was going through a divorce are still amazed that I was able to finalize it in less than a year. Leslie and her team made that possible with their impeccable work, professionalism, and dedication. She treated me like family, kept me informed, and was always one step ahead—no ma...tter what my ex threw our way. Leslie secured a settlement beyond what I expected and helped me realize I truly deserved it. Her associate, Ms. Heikkila, and the entire staff—including the receptionist, Madison—were always kind, knowledgeable, and ready to assist. No matter when or how many times I call, someone was available to answer my questions or provide the help I needed to ease my concerns, showing the team's outstanding commitment. If you need a sharp, compassionate, and results-driven attorney, I highly recommend Leslie. She goes above and beyond, and I’ll always be grateful for her exceptional service!
