nada picAtelierista (Art Teacher)/ Curriculum Specialist: Nada Martin 

Hi, my name is Nada Martin and I am excited take on the role of Atelierista at Mixed Greens! I studied Art at Occidental College in Los Angeles and at the University of California at Berkeley. After completing my BA in the Practice of Art at Berkeley, I continued my education at various institutions in the Bay Area with a focus in Early Childhood Education, and earned my Multiple Subject Teaching Credential from San Francisco State University. I have familiarity and practice with many modes and methods of education, including training in the fluid, constructivist, and experiential Reggio Emilia approach. I have had a 20+ year career in Early Childhood and Elementary Education. I am passionately committed to educating the whole child; heart, body and mind, while fostering critical thinking, independence, compassion, and a lifelong love of learning.

I especially love sharing nature and doing art with children.  It is serendipitous that Heather and I have found each other because we share a common formative influence on our philosophy about the education of young children. We both devoted part of our careers to working at the same preschool in Mill Valley; however, our paths did not cross until we both came to be in Santa Rosa!

 I am of Lebanese and Anglo American descent (Lebanese dad, Anglo mom).  I grew up in the Middle East and Europe, and came to the U.S. during summer trips to visit my mother’s family, and, eventually, for college.  I live in Santa Rosa with my husband, Tony, our son, Dante, our playful mutt, Darwin, and our laid-back turtle, Slider.






Organic Gardening Teacher: Shona Vargas-Smith shona

Hi, My name is Shona. I have been at Mixed Greens for five years, initially focusing on Science and Math, then moving in to the Garden, where I enjoy blending Science experiments and Earth learning!

My daughter India goes to the French American Charter School. I believe that everyone should know two or more languages, and I think it’s silly that America only requires English.  As an SRFACS mama, I also supervise the Walking School Bus for the Camp Ever Greens kids coming over from the French American Charter School!

I have a Bachelors Degree in Cultural Anthropology and Liberal Arts that I received from San Francisco State. I also have a Multiple Subject Teaching Credential from Sonoma State. After getting these credentials I realized that my heart is in young children. I love to see their excitement of coming to school and learning new things. I love to witness the big stages of a child’s life such as learning to talk or not needing to wear diapers anymore. I get to learn new things everyday, but at a child’s perspective…And that gets me excited to come to work everyday!

I have been a vegetarian most of my life and have always eaten lots of vegetables. Eating mixed greens almost everyday…I am excited to be introducing veggies to kids and have them try new things. I have a garden at home that includes veggies year round, native plants, and many kinds of fruit trees.

When I am teaching the kids I like to incorporate a lot of art and books into what we are learning. Don’t surprised if you hear of a crazy science experiment, I love to do those too! I believe that people should always try and learn new things…Working at Mixed Greens allows me to do that!







Organic Gardening Teacher: Kimberly Barbosa Soeiro

Hi!  My name is Kimberly Barbosa Soeiro (Miss Kimmie), and I am excited to join the Mixed Greens Garden Team!  I’m a graduate of Sonoma State University and Mills College, and a student of herbalism and permaculture. I have previously worked in non-profit organizations, designing and implementing youth programs focusing on health, nutrition, and social justice. One of these programs is the well-known Active Play Every Day program that runs throughout Sonoma County, and encourages children to engage in active recess to promote motor skill growth and interpersonal development. I studied Permaculture Design at the Occidental Arts and Ecology Center, and received training at the OAEC’s School Garden Teacher program, where I gained skills related to age appropriate lessons about seed-keeping, soil biology, movement and mindfulness, biodiversity, and organic practices.  In my free time, I regularly volunteer at organic farms, gardens, wildlife stewardship programs, and enjoy tending to orchards, gardens, pigs, chickens, and maintaining a wildlife corridor at my home ranch.  I am thrilled to be a part of Mixed Greens, and happy to learn and share with people of all ages and abilities!








Heather & Violet

Teacher: Heather Harrison

Hi there, my name is Heather Harrison. I am more than thrilled to be a part of this amazing community of Mixed Greens! I completed teacher training hours at Mixed Greens years ago, and have been the Director/Counselor at Camp Ever Greens and a substitue at Mixed Greens for about 3 years now. I am now enjoying being a Seedlings co-teacher at our Farmstead campus.  Ever since I was a little girl, I have always had a passion for the outdoors. Gardening, camping, and running cross country were a few of my favorite activities. I have also had an extreme connection with animals, always training my dogs’ basic obedience and specialty tricks as well. I was a very active FFA (Future Farmers of America) member in the Campbell, CA Chapter, competing in speech competitions and raising and showing animals, receiving 2 blue ribbons…I raised three pigs, a lamb, two turkeys and shared a steer with a fellow FFA member!

One of my greatest memories when I was younger was attending science camp. Remembering how much joy it brought me singing songs and learning about the earth around me fascinated me and I am so excited to be given the opportunity to share that same joy with other children.

I have my Camp Director certification from the American Camp Association, and earned my Child Development teaching certificate from SRJC.  I started this new direction in my career because of my daughter, Violet. The day she was born, a love for children bloomed that I had never realized I had before her arrival.  I started taking Child Development classes to ensure that I am doing everything I can to become the best mother possible. In doing so, I realized I have a talent for teaching and a passion for guiding new sprouting minds! Working for Mixed Greens and Camp Ever Greens, I am given an opportunity to extend my knowledge of development and nurturing to benefit other children as well as my own.  I am so excited to get to know all of these wonderful children and their families!






Environments Teacher:  Cam West

Hello! My name is Cam and I am so excited to be a part of Mixed Greens and the positive impact that it is bringing on our community! My passion for working with children stems from my own past and upbringing, growing up in a big family where every day was taught to be an adventure, there was never a dull moment. My parents encouraged all of us to learn with our hands, interact with nature, and explore the beauty in all cultures, languages and ethnicities. To this day, I watch them help any child in need and I strive to follow their glowing example.  I am currently working towards my Child Development degree through Theoria College.  I am the Environmental Teacher at the Farmstead Campus and enjoy spending as much time as possible at the Hoen (OG) campus as well!

I enjoy the privilege of assisting children in therapeutic horseback riding, and love introducing Mixed Greens kids to animals right in our own backyard. I believe the connection between child and animal plays a vital role in their emotional development as well as building up a sense or responsibility and trust. Another passion I have is teaching music. Music is the universal language in which anyone including children can express themselves in any language or even without having to speak a word. Seeing a child really ‘feel’ music is one of the most rewarding things anyone could ever experience. When I am not outdoors you can bet I am thinking about when I can be outdoors again! We live in a very high-tech world so helping a child find the magic within nature is even more so important to me! A few other activities I love teaching and sharing are Archery, Loom crafting, Farm maintenance, and Swedish/Spanish/Vietnamese language learning. I am so happy to be a part of such an inspirational school and team who’s goals match my own!




Spanish Teacher:  Giselle Vigil

Hello! My name is Giselle Vigil I am so happy to have the opportunity to be a part of such an amazing group here at Mixed Greens. I was raised in California’s central valley and moved over to Sonoma county when I married my lovely husband. I am fluent in English, Spanish, and American Sign Language. As a part of the Mixed Greens team I want to help children learn, explore, and grow into curious individuals. My goal is to create an environment that makes the children feel safe and loved. I am so excited to see what Mixed Greens has in store for me, let the adventure begin!

I started my career with children at the age of 16. I began working for a non-profit organization that offered after school tutoring and mentoring to children ages 5-17, since then I have worked in elementary schools, high schools, and as a nanny. It wasn’t until I was a sophomore in college that I decided to switch my major from Pre-Nursing to Early Childhood Education, I now have my Associates in Arts in Early Childhood Education and my certificate in Early Childhood Education Associate Teacher. Most recently, I completed Spanish Immersion Teacher Training with the fabulous Guadalupe at Colors of Spanish (our long time Spanish teacher) and I have had so much fun sharing what I’ve learned and putting my own twist on our Spanish program here at Mixed Greens!  Typically, you will find me at the Farmstead campus, but I visit the OG weekly for Español!




guadalupeColors of Spanish: Guadalupe

Guadalupe, a native of the Bajio region of México, has been teaching Spanish to children and young adults in this area since 2003. Guadalupe has been bringing Colors of Spanish to Mixed Greens since 2012 and is a much loved member of our community!  She is part of the El Día de los Muertos, Petaluma committee and in 2011 was among seven individuals named as Latino community leaders in Petaluma by the Argus Courier. She has a Master’s Degree in Spanish, with a focus on early age acquisition of foreign language. Her classes encourage creativity, energy and the spirit of play!

She is the founder of Colors of Spanish, an early childhood language-learning program that has provided classes in schools, preschools and community centers in Sonoma and Marin Counties since 2004. Most recently, she trained our own Giselle to follow in her footsteps as a Spanish Educator!





Floater Teacher:  Lauren Johnson

Hi, my name is Lauren Johnson and I am so happy to be a part of the Mixed Greens Family! I recently graduated high school and I’ve been taking care of children and infants for over four years. I grew up as the oldest of five children in my family, so I love being around young, imaginative minds. I’ve always wanted to work with children, helping them grow into loving and respectful members of the community and now I get to live my dream. 

Coming from a very artistic family, I love helping children discover their creative side. I have loved music all my life and enjoy playing ukulele and guitar in my free time. On top of that, I enjoy the creative and therapeutic benefits of painting and other mixed media art forms. I consider it a wonderful opportunity to be able to share these passions of mine with children of all ages.






Movement Teacher: J.J. Johnson

My name is J.J. and I am incredibly grateful to be a part of the Mixed Greens community! My love for working with children began in high school, when I started teaching dance classes to some aspiring ballerinas who, little did they know, were really the ones inspiring me. Motivated to continue down the path of teaching, I found myself in the Early Childhood Studies program at Sonoma State University.  I was quickly drawn to the professional field of Early Childhood, and am continually inspired by the individuals who make up this valuable community. Working in various classrooms throughout my time at SSU allowed my appreciation and passion to grow even more. After receiving my Bachelors in Early Childhood Studies in 2017, I spent a year teaching at My Gym Children’s Fitness Center here in Santa Rosa. I loved being able to help provide a place where children and families could play, learn, and grow together. I believe the value of play should take an active role in children’s learning and that education should emerge from children’s own interests.

When being introduced to Mixed Greens, I immediately knew I had found a community that shares my values and beliefs. It is important to me to create an environment where every child feels safe and supported. I believe it is only then that we can teach the whole child and help shape them to be life long learners. It is with so much joy that I get to be here at Mixed Greens and I am so excited to be a part of this wonderful family!










Substitute Teacher: Courtney Hunter

Hi everyone, I’m Courtney Hunter, and I’m very excited to join the staff over here at Mixed Greens! I’ve been working with kids for the past 15 years as a preschool teacher, nanny, summer camp counselor, and field trip teacher. In 2008 I received my AA in Child Development at the SRJC right here in Sonoma County where I was born and raised.

Being a part of a young child’s learning experience is an incredible gift and learning lesson for all involved! Taking time to slow down and explore our curiosity about the natural world, figure out how things work and experiment with creative expression through art/movement/music/building/language are things that I love to encourage in children at any age (including us “grown ups”)!

Besides teaching, some of my other passions include gardening, creating visual art + music, traveling as much of the globe as possible, and volunteering in my community.  I look forward to meeting you all and continuing this learning journey together!

Substitute Teacher: Cara Viripaeff Baum

Hi, My name is Cara Viripaeff Baum. I am overjoyed to be a part of the Mixed Greens Family! I earned my Early Childhood Education credits at City College in San Francisco while working on my BA in Pyschology at USF, eventually completing my Masters in Teaching English to Speakers of Other Languages from SFSU and Multiple Subjects Clear Credential through SJSU. I have worked as a therapist for Early Intervention and taught kids and adults: preschool, k-8, high school, college, university, and adult-ed, in addition to all sorts of other fun stuff including being a nanny, camp counselor, mom, and step-mom.

I found Mixed Greens while looking for an amazing preschool for our daughter. As a mom of a micro-preemie, well versed in sensory and neuro needs, I was thrilled to find a Reggio Emilia inspired school with a philosophy based on experiential, social learning in a green environment that provides children lots of space to play, explore, and get dirty. I hope to bring my passion for early childhood education with an understanding of RIE, multi-cultural, and mindful classroom philosophies.  I also speak Spanish and in my free time you can find me on the trails as a volunteer bilingual docent with Landpaths or exploring fun places to play with our three kids, friends, and family!

amyNutrition / Rainbow Greens: Amy Hudgens

My name is Amy Hudgens, and I am the Nutritional Consultant for Mixed Greens and two other local preschools.  I am honored and excited to announce a new program that we started here the first week of May 2012. Mixed Greens agreed to be the Pilot school for my Nutrition Program for Preschoolers called Rainbow Greens!  I am also a mother of a toddler and know how busy life can get and how important it is to stay nourished inside and out. I am grateful that my dreams and visions are finally coming alive with the start up of Rainbow Greens! Rainbow Greens was developed with the intention of making learning about nutrition fun and educational for the kids. I want to keep it simple with a huge focus on organic whole foods, short fun educational lessons, and little cooking demos.  I will also be providing parents with 2 free cooking classes per calendar year so that the whole family can be involved. Also, with every monthly lesson, each child with get a card with “health tips” or a nourishing recipe on it to share with their family. I am so excited to start this program. Thanks to Mixed Greens for helping so much get this program started! Be Well, Amy Hudgens
