Our Staff

Kelley Cohen

Administrative Director

It is an honor and a privilege to work with the children, parents and teachers at Tree of Life Learning Center every day! I began my career over 20 years ago, teaching elementary education. I love being a teacher. I love the look on a child’s face when they are asking a question and the satisfaction they have when their curiosity has paid off and they have found the answer! I love being a director. I love watching the teachers develop and grow into your children’s heroes. I opened this school in August 2011 and it was one of the best decisions I have ever made. It has given me an opportunity to bring the kind of culture and values to the early education of the children in our community. I love working in the community in which I live with my husband and our three children. I hope to instill a love of learning into my own children and all the children at Tree of Life Learning Center!

Kerri White

Hi! My name is Ms. Kerri. I was born and raised in Fremont and moved to the Danville area in 1993. I have been with Tree of Life Learning Center since August of 2014. When not working I enjoy taking my daughter to sports games, cheering on my nephews in their games, and spending time with family and friends. I have 20+ years of experience working with children.  My main goal in the classroom is not only to provide a loving environment for the children but to also enrich their lives with learning while having fun. I became a teacher because I love kids! I like to get messy and explore!

Zvia Bitansky

Hi! My name is Ms. Zvia. I was born in Israel and grew up there. I attended a vocational high school learning drafting and other architectural office skills. After serving in the Israeli Army, I worked for an architect in Tel Aviv. In 1981, my family moved to San Francisco. Soon after settling in the East Bay, I began to study preschool education and worked in the preschools at Contra Costa Jewish Community Center, Temple Isaiah, and B’nai Shalom. During this time, I completed the curriculum in Early Childhood Education at Diablo Valley College and earned numerous certificates. I bring the richness of Judaism to my classroom and with every small dose of Judaica, enrich the learning environment. I love introducing the children to the world, to language, music, and art. I have for many years watched children gain knowledge through experience as I encourage their curiosity. I am the one honored to guide their curiosity.

Jessica Mikkelson

Hi! I’m Ms. Jessica. I am a bay area native and have lived most of my life in the Concord/Clayton area.  After high school I went on to study nursing at the University of San Francisco. However, while working part-time as a daycare assistant I realized that working with children was my true passion and more aligned with my personality and purpose. I have since worked as a daycare assistant, nanny, and various other early educational roles for over seven years while concurrently obtaining my degree in early childhood education. I am a lover of learning and am always looking to improve myself or my skills. As a teacher I hope to instill that same enjoyment for learning into the children. In my spare time, I enjoy hiking, cooking, watching movies, and being crafty!

Ann Mata


Hi, I’m Ms. Ann! I was born and raised in the Bay Area and attended schools in San Ramon from kindergarten through high school. I graduated with my BA in Sociology from San Jose State University and volunteered most of my time in schools where I fell in love with teaching. Since then I have been a nanny, kindergarten assistant and recently worked in a special education preschool. My favorite thing about teaching is being introduced to so many new families, cultures, and personalities. I love the unlimited possibilities of how to help kids grow and get them excited about learning. I’m happy to be a part of the Tree of Life Learning Center team!

Lupe Griffen

Hello, my name is Ms. Lupe.  I have worked with preschool aged children for over 15 years and love it! I have been married for 30 years and have four adult children. I also have 3 dogs. I am excited to be at Tree of Life! I am always ready to take on new experiences and of course have fun with all of the children here.

Kelsie Natsch


Hi! I’m Miss Kelsie, I have been a preschool teacher for 4+ years! I attended Las Positas and Diablo Valley College and studied Early Childhood Development. I have always had a passion for working with children and ever since I was young, I knew I wanted to become a teacher. I am so excited to work with your children and help them develop a love of learning here at Tree of Life!

Lilly Fehrmann

Hi! my name is Lilly. I grew up in Pleasanton and currently still live there with my family. I grew up with a daycare in my parents’ home and have always been surrounded by children. When I am not at work, I enjoy baking, watching movies, and doing different art projects.  I’m glad to be a part of the Tree of Life community!   

Logan Thompson


Hello, I am Ms. Logan! I was born and raised in the Bay Area (Pleasant Hill) and attended Arizona State University to receive my Bachelors in Educational Studies. During my Bachelors program I took Early Childhood Education courses and volunteered, and found my true passion of teaching little one's. I quickly realized how amazing it is to be such an important part of each of my students' lives. I love watching them grow and explore in new ways that make learning truly an experience! I hope to be able to instill a love of learning in all my students and provide them with all the skills and tools needed for a lifetime of learning!

Ana Segalini


Hello, I am Ms.Ana! I was born and raised in Peru. I grew up in a multicultural environment. My mom was Japanese and my dad was Italian. I knew early on that I would work with children. Being a teacher is a dream come true for me. I competed my California State requirements in 1991 earning credits from Merritt College, Hayward State University, and Mills College. I have been wroking in the field for over 31 years in several different capacities, from head teacher, site director, assistant director, and eventually running my own home preschool for several years. I am thrilled to be a part of Tree of Life Learning Center. It offers me the perfect balance of work and life. I am excited to provide our children with new experiences in which they can use their imagination to be creative, and help them in their early development. I want them to enjoy their childhood and also enjoy learning. In my free time I enjoy cooking, collecting antique purses, spending time with my family, and our dog Emily.
