Greg Garrison, Science

“Somewhere, something incredible is waiting to be known.” (C.Sagan)


Greg has been teaching for decades with the goal of helping students discover the wonder, the incredible, and the amazing all around us and in us.  Whether we are looking at the vastness of the universe and how a star is born, or considering the simplicity and complexity of a DNA molecule, if one brings what they are looking at into focus, one cannot help but discover how amazing it all is.  Greg has taught every level of student from 5th grade to PhD candidates and long ago discovered his own love for middle school students.

Middle school can be a very chaotic time for a young person. Along with the increased academics, students are discovering the wonder of who they are and deciding what kind of person they want to be. It is a time when our students are questioning everything, desiring to be adults, and at the same time still longing for the guidance and safety of the grown ups that love them. Greg, embraces the opportunity to teach, guide and support our middle schoolers during this journey helping them to achieve their true potential both personally and academically.

Marissa Klein, English

Marissa's favorite part of teaching middle school English is helping kids find books they love and then setting them on the path to become lifelong readers. Her goal is to guide students in understanding how to read, write, and tell stories across multiple genres and styles. In so doing, the students gain a greater understanding of themselves and the world around them. She appreciates the curiosity and quirkiness of middle schoolers most of all. For over ten years, Marissa has taught grades six through ten in independent and public schools in the Bay Area, which has given her a clear vision of what skills students need as they prepare to enter high school English courses. Previously, Marissa worked in journalism, marketing, and consulting before discovering her passion for education while teaching English as a Peace Corps Volunteer at a university in China. Marissa is from Southern California, where she attended a beloved independent K-8 school similar to AVS. She has been in the Bay Area off and on since 2004, when she moved north to attend Stanford. When she's not teaching, Marissa enjoys traveling (she has visited nearly 70 countries) and updating her spreadsheet of every book she has read.

Kristin Landowski, Art & Tinker

I have been an artist my entire life, but at the tender age of 7, I found art, clay in particular, as the vehicle to find myself, my individuality, uniqueness and expression." Art allows the space to discover and try to connect all the things we question in the world. Art creates a place to explore those questions through a multitude of different mediums in which we can express. Kristin is constantly problem-solving to make sense of the world we live in and question how art can inspire, complicate, address social injustice, question and make the world a better place. She believes that art can save lives and create a community.


Kristin has a plethora of experience teaching all ages. She managed an art center in the Midwest, designing and teaching classes to young students  and to the young at heart. Upon moving to the Bay Area, from the center of Wisconsin, she began teaching at multiple art centers in the Bay Area, prestigious independent high schools and at the California College of the Arts. Her skills are bountiful with experience in ceramics, sculpture, drawing, painting and creating installation work and art via interdisciplinary means.


Art is the space when words fail that imagery, designing, making and creating become the driving force to express our inner most thoughts, feelings and things we question. Kristin is interested in showing her students how art, history, science, math and writing all coalesce.  Creating a safe place for students is paramount for them to explore, push the boundaries and fail with grace. It is through our failures that we learn the most about ourselves and hone our problem-solving skills, and grow. Art is everywhere and in everything. “I believe that we are all artists.

Andrew Verrilli

Andrew has had a passion for math and science for as long as he can remember. It was no

surprise he fell in love with computer science after taking an introductory course in high school. Initially, Andrew had aspirations of starting his own company like his father, and it was not until his sophomore year in college that he became interested in education. As a teaching assistant within Bucknell’s Computer Science department, Andrew’s passion for teaching grew rapidly. He would teach lessons and he even wrote his own code to automatically grade assignments, much to the relief of his fellow TAs. After graduating from Bucknell University in 2019, Andrew immediately started taking education courses at the University of the Pacific. 


Andrew tries to create a classroom that encourages exploration and creativity. He enjoys working with other teachers to make lessons that apply computer science to everyday situations.
