Advisor to the Acting Head of School

Lee Drolet

Lee is the former Head of School at Presidio Knolls. She is a longtime educator who hails from Minneapolis, Minnesota, where she spent 35 years as a teacher, school principal, and educational leader. During that time, she founded and built one of the nation’s most respected public school Mandarin immersion programs from the ground up -- from recruiting teachers, to introducing the concept to skeptical parents, to building and testing the curriculum. In addition to her extensive experience in Mandarin immersion, Lee also led a well-known program for highly gifted students in the Minnetonka, Minnesota, school district.

Lee received her BA, MA and EdS degrees from the University of Minnesota, Twin Cities. She and her husband Peter live in Sausalito and share four adult children. 

Head of Middle School

Mike has spent his career educating students around the world -- he has taught history, literature, economics, humanities, and Chinese in the United States, Israel, and China. He has taught in boarding schools and day schools, middle schools, high schools, and universities. He is a proficient Mandarin speaker.

Mike began his career teaching in Quaker schools in the Philadelphia area. He then moved to China to teach at Guizhou University. After returning to the U.S., Mike taught at Saint Paul’s School in New Hampshire, and Saint Ann’s school in Brooklyn, New York. Most recently, as Associate Division Head of grades 6-8 at Avenues, The World School in New York City, he led hiring, faculty evaluation, coherence of curriculum, and overall success for the Middle School. Avenues is a new breed of global educational schools with a focus on bringing progressive learning to campuses around the world.

Along with his teaching, Mike is also an author. His memoir, Kosher Chinese: Living, Teaching, and Eating with China’s Other Billion, won multiple literary awards and was a New York Times bestseller. His shorter work has appeared in numerous anthologies, magazines, and newspapers.

Mike graduated from Cornell University in 1998 with a BA in philosophy and religious studies. He met his wife, Ines, in his freshman dorm. Mike received his MAT from Columbia University’s Teachers College. He has also studied at the Conservative Yeshiva in Jerusalem, Israel.

Mike and Ines have a three-year-old daughter, a one-year-old son, and a five-year-old dog, Tudou. All members of the family love dim sum, except for Tudou. He prefers Sichuanese food.

Head of Elementary

Renee Miller

Renee is an educator and teacher mentor with more than 20 years of classroom experience. She has deep expertise in progressive learning, with particular emphasis on curriculum development and issues connected to assessment, inquiry, and social emotional learning. She is also an expert in the fields of math and maker education, and she has extensive experience in providing and leading professional development for teachers. 

Renee completed her graduate work at Bank Street College, a school founded in the tradition of progressive education, where she earned an MS in educational leadership with a special emphasis in math education. Prior to joining PKS, she served as a teacher, math specialist, and classroom mentor at Park Day School in Oakland, one of the leading progressive schools in the country. While at Park Day, she worked under the direct tutelage of Tom Little, the visionary progressive educator and author who led the school for nearly 40 years. 

In 2012, Renee joined Agency by Design, a multiyear research initiative at Harvard University’s Project Zero. As part of this team of teacher researchers investigating the promises, practices, and pedagogies of maker-centered learning, Renee focused on developing instructional strategies and tools to help students think deeply about the design of ideas and systems. Her work is featured in the hands-on guide and theoretical framework Maker-Centered Learning by Clapp, Ross, Ryan, and Tishman.

Renee loves grappling with issues related to gender, equity, social justice, leadership, and mathematics education. She has presented both nationally and locally on issues of progressive education, maker-ed, mathematics, and teacher excellence and leadership. 

When not engaged with work at PKS, Renee can be found digging holes and building driftwood sculptures with her wife and daughter at local beaches. A Bay Area native, Renee loves the A’s and Giants equally, finds deep comfort in foggy mornings, remembers well the ‘89 AND ‘84 earthquakes, and comes by her snobby foodie ways naturally.

Head of Preschool

Simona Chongo

Simona has led the innovative Presidio Knolls early childhood education program since 2009, shortly after the school’s founding. As a parent, former Board member, and school leader, she has played a central role in creating the warm, loving environment that makes the PKS preschool such a special place. 

Simona is passionate about children and works tirelessly with our parent association and staff to create a respectful, diverse, and vibrant community. She is especially committed to fostering our twin goals of progressive Reggio-Emilia inspired education and Mandarin immersion.

Simona and her husband have two daughters who are being raised in English, Mandarin, and Romanian. Her family enjoys traveling around the world in the summer and skiing during PKS breaks.

Simona has a BA in Languages and Literature with an emphasis in American Cultural Studies, as well as teaching credentials from Bucharest University in Bucharest, Romania. She is fluent in English, Romanian, and French and loves practicing her Italian and Spanish every chance she gets.

Director of Admission

Ron Yu

Ron has served in multiple capacities at PKS since he joined the community as a parent in 2011 - member of the Board of Trustees education committee, chair of the Board Head of School search committee, and co-director of the school. In his current role, Ron serves as the first point of contact for prospective students and families and is charged with shepherding each family’s transition into the PKS community.

Prior to joining the PKS team, for the past 20 years Ron has played startup and leadership roles in education, nonprofit and business organizations. After beginning his career as a third grade teacher in nearby Oakland with Teach for America, Ron moved into nonprofit management and worked as a consultant at Deloitte. In addition to these experiences, he helped build an international technology startup, expanded and oversaw the leadership training program for the renowned KIPP charter schools, and launched and managed a charitable foundation that has raised over $12 million for brain tumor research and patient care.

Ron holds a BA from Stanford University and an MBA/MEd from the University of Washington. While he is conversant in Mandarin, he still enjoys learning new words and songs from the PKS preschoolers. 

Ron and his partner Jane spend their time outside PKS chasing their five children around the parks and museums of the Bay Area. He will be the first to tell you that being around children at home and work is truly the fountain of youth.

Director of Auxiliary Programs

Kristina Coleman

Kristina has been the Director of Auxiliary Programs at PKS since 2014. She is an experienced educator and program manager who has spent many years delivering hands-on learning experiences to children. In her current role, Kristina works to enhance and expand enrichment opportunities for students on and off campus. She develops relationships with external providers to offer educational and engaging classes. 

Kristina is passionate about the afterschool program because it gives children an opportunity to widen their interests, find what challenges them, and let loose. She believes the non-traditional classroom environment leads to new and exciting experiences, which allows children to find their passions. 

Prior to joining PKS, Kristina worked in many educational roles. She taught as a preschool teacher in South Carolina, provided one-on-one ABA therapy services to children removed from their homes, and helped run a program that provided alternative care to dual working families.

Kristina graduated with a BA in elementary education from the University of Minnesota. She is currently taking Mandarin classes (ni hao!), and she is constantly learning new words and phrases from the students and teachers. In her free time she enjoys baking, bicycling, drinking coffee and exploring the city.
