Over the years, Tressa has assumed various leadership roles at MUSE, most recently becoming director of Middle High in 2023. A true believer in all of MUSE’s 5 Pillars, Tressa feels blessed to work in a school that encourages innovative life-long learners while teaching them to advocate for themselves.

Megan Grieco

Director of K-12

Megan Grieco — MUSE Global Director of Upper and Lower School — has dedicated her last 15 years to revolutionizing (and evolutionizing) primary and secondary education. Megan’s passion for education, environmental and social justice, and teaching young people how to listen to their minds and bodies, is everpresent in her teaching and leadership. After earning a dual masters in Literacy and Special Education, Megan relocated to Southern California to lead a play-based childhood education program and to pursue teaching opportunities that aligned with her philosophy on how education can excite young people about their relationship with each other and planet Earth.
When Megan discovered MUSE, she knew she’d found a new home. Since joining MUSE Global School, Megan has served as a teacher and co-chair in MUSE’s Elementary, Middle, and High School departments. Megan’s dedication to broadening student perspectives and fostering academic achievement saw her embrace leadership roles in MUSE’s Diversity, Equity, Inclusion, and Justice steering committee, curriculum revision team, and special education resource management.
Megan is thrilled to serve as MUSE’s Director of Lower and Upper School and knows that, “Each of us have the power to shape our world with how we educate young people.”



Melissa Cardoza

Director of Business and HR

Melissa has been with MUSE since February 2015. Melissa is extremely passionate about MUSE’s mission, vision, and plant based and sustainability practices. When she first heard about MUSE, there were unfortunately no open positions so she started as an unpaid intern. She quickly was promoted and worked her way up throughout the years with the guidance and mentorship of individuals on the Admin Team.

Melissa was born and raised in the San Fernando Valley and attended UCLA where she received a BA in Sociology and Civic Engagement in 2012. Melissa now resides in South Orange County with her husband, children and vizsla pup. In her free time she enjoys spending time in nature, going to the beach, running, hiking, reading, cooking and enjoying the company of her family.
