Erica Hamlin and her husband, Nason, came to the Island as part time residents in 1991. Erica earned degrees in Biology and Molecular Biology at Smith College (MA) and Wesleyan University (CT). She taught (Biology, Music, Ethics, and English) and was an administrator (Science Department Chair, Dean of the Faculty) at The Hotchkiss School in Connecticut for 20 years. In 2002, Erica and Nason moved West where she took on the position as Head of School at University Prep in Seattle, and Nason as a Clinical Professor of Medicine at the UW. After twelve years, they retired and became full-time Island residents in 2014. They have five children and five grandchildren.

Erica has devoted much of her professional career to inculcating within her school communities social justice and equitable access. She feels strongly that proactively sustaining functional diversity is essential to humanity, and that it takes hard work to make it happen. The SJCHT embodies that ethos.

Erica has also had extensive board experience as a trustee across several disciplines, most recently with the Seattle Chamber Music Society and the Pacific Northwest Association of Independent Schools.
