Rosalind Diaz | operations manager + Tutor supervisor

she/her
Rosalind loves helping students build the skills and habits that support long-term academic success. Her tutoring style is infused with warmth, humor, and a lively spirit of curiosity. She works with each of her students to set reasonable goals and practice sticking to a plan over time. She especially loves to help young people feel more confident about their math skills and tap into the creative side of math.

Rosalind recently completed a Ph.D. in English at UC Berkeley, where she received two competitive awards for excellence and innovation in teaching. She holds a B.A. in English from Yale University. Both her parents are mathematicians, so she’s maintained her love of math through all those years studying English! In her free time, Rosalind can often be found crafting 3D geometric origami sculptures of various shapes and sizes.

Teresa Pham-Lac | Finance + Workshops Manager

she/her
Joining Classroom Matters in 2016 after moving to the Bay area from Los Angeles, Teresa is the only staff member that does not tutor any students. She’s an integral part of CM’s Admin Team, handling all aspects of billing and finance, and everything related to workshops.

Born in Minnesota, Teresa has spent most of her life in various California cities: Riverside - where her parents still reside, Los Angeles - where she went to college, El Sobrante - her Bay Area home where she lived with her fiancé-turned-husband, and now currently Elk Grove - where she’s enjoying life with her daughter as a family of three.

She has worked at various places including a non-profit organization that supported women entrepreneurs, a luxury private aviation company, and two telecom companies. Outside of work, she is an epicure and likes to explore restaurants, Michelin Star eateries, and recreating dishes from favorite meals. She also travels as much as she can and enjoys planning her next vacation. Beyond that, Teresa likes playing mah jong, gardening, watching sports, playing board/card games, stream movies and shows, and spending time with her favorite people over good coffee, fun cocktails or yummy eats.
