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

Core Teacher & Gymnastics : 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:  Maestra Ofelia

Ofelia is originally from Nicaragua and arrived in Sonoma County in 2018, where she is journeying through the adventure of raising a bilingual family with young children. Through Colors of Spanish, and as a provider of Preschool Spanish to a number of Santa Rosa preschools, she is enjoying the sharing of Latin American culture and history to the next generation of multi-cultural and bilingual Californians. You can often find her at local Spanish Story Times – either as a provider or participant as she further develops her skills as a language leading instructor and mother.




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.








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: Kathy Kuula

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!

Substitute Teacher:  Megan Izen 

Hi, I’m Megan and I am so grateful to be part of the Mixed Greens community, especially opening the new Lia Lane location! I have my Bachelor’s degree in Women’s and Gender Studies with a minor in Mathematics from Sonoma State University, and my Master’s from CUNY Graduate School of Journalism.

My nephew is a Mixed Greens graduate and I fell in love with the Mixed Greens philosophy visiting him at school, picking him up and hearing the exciting things that he did, and exploring with him on many amazing field trips. After living in New York and spending time abroad, I’m back in Sonoma County and excited to start this journey with your little ones at Mixed Greens!

I speak Portuguese and Spanish, I have a very curious toddler (who is also a Mixed Greener), and when I have a free moment, I’m usually experimenting in the kitchen.
