    Miren was opposing counsel on a case of mine, and I highly respect her. While always courteous and professional, she was a fierce and thorough litigator in advocating for her client. I hope to have Miren as opposing counsel on future cases.

    I have known Miren for several years, since 1997 when we both worked in the same law firm. I know her to be an incredibly smart advocate who consistently gets very good results for her clients. I would refer civil cases to her with absolute confidence.
