WHAT CLIENTS SAY

"I get excellent results with Marjorie and it's a pleasure to work with someone who is so smart, effective, and no nonsense."

MY CLIENT PHILOSOPHY

"I strive to be a trusted advisor, not a mere provider of legal services. In my mind, client service goes beyond delivering excellent results – it means doing so in a way that respects both our clients and their stakeholders, and acknowledges that we, as a firm, are fortunate that they entrust us with their most significant matters."
