In matrimonial law, one size does not fit all. I love breathing new life into long-established arguments. Taking positions that haven’t been taken before is what I do best and what drew me to law in the first place. Each unique client deserves an equally unique outcome. I pride myself on thinking creatively for my clients and connecting with them on a personal level so that together, we can build a distinctive pathway to their future.
