The name Marrin rhymes with Sharon,
but the meaning is all about Grandma Ruthie...
Our founder draws inspiration for naming the firm from her remarkable grandmother. Born Ruth Marrin, a formidable force despite her petite stature. Standing at just 4'11", Ruth exuded strength as she lovingly managed her household of seven children and extended warm hospitality to all. In a time when higher education was uncommon for women, she defied expectations by studying four languages and a range of liberal arts courses at her university. Ruth's insatiable thirst for knowledge and elegant grace persisted throughout her life and became a legacy cherished by subsequent generations.
