Outside the classroom, Rachel has dedicated 15 years to coaching swimming for various age groups, enhancing her understanding of building authentic student-teacher relationships. This experience taught her that connections made beyond the classroom walls often pave the way for trust and mutual respect inside the classroom.
Since moving to Petaluma in 2020, Rachel spends her free time exploring the world with her young daughters, her husband, and their fluffy cat, Mikayla. She views every day as an opportunity to learn something new, embodying the spirit of lifelong learning we cultivate here at Spring Hill School.
