Sierra Antonio is a graduate of Dominican University and has been living in the Bay Area since 1999.  She previously worked at The Marin School, a small independent high school in San Rafael.  She began her career at TMS in 2011 as an Admissions and Development Assistant and slowly grew into the role of Director of Admissions, Marketing, and Communications.  She has a strong affinity for any and all creative work, such as photography, graphic design, and video production.

Sierra lives in Petaluma with her husband and son and, in her “free” time, loves to hike, bake ambitious cakes and play music.  She is very excited to join The Healdsburg Community!
