The school has had a profoundly positive impact on her family and son, Charlie (Class of 2023), who has been given a sense of community and belonging at Brandeis that is far from given for a kid as seriously disabled as he is.  Mariah has actively volunteered at Brandeis since her son entered kindergarten, including serving two years on the Executive Board of the Parent Association.  Before having her son, Mariah worked in special education and women's health. Both of these areas were places in which she found a passion for service, and a deep interest in problem solving to cater to individuals' needs across a variety of settings. Mariah is an avid hiker and loves all things nature. She grew up in Chicago, but has lived in the Bay Area since 2001 and has lived in Fairfax since 2011 where she lives with Charlie and their two dogs.
