    I have known Cat Koshkin for many years. She is considered one of the finest probate and estate planning attorneys in our community. In fact she is my estate planning attorney and I have been totally satisfied with her representation over the years. She listens carefully and provides conscientious considered guidance and advice. In my book she is "10" - "Superb"
