José Salomón Sánchez was born in Guanajuato, México to a family of farmers and small business owners. Salomón grew up in a large Catholic household, where he helped out with the family business and enjoyed a free-range childhood a la Huckleberry Finn. José and his family migrated to the United States when he was 14 years old, ultimately settling in Monterey County, where his grandparents had worked as Braceros in the 1960's and his father and uncles as seasonal agricultural workers in the 1980's.

José went on to study at the University of California at Berkeley (Roll on, you Golden Bears!) where he obtained degrees in Mathematics, Spanish Linguistics, and Education. Shortly after his graduation, he founded the Greenfield Community Science Workshop (Greenfield CSW) in 2011, though everything he knows about CSW's he learned at the Watsonville Environmental Science Workshop.  To José, the defining characteristics of a CSW are a) their commitment to social justice -- CSWs are located in underprivileged neighborhoods, b) their genuine connection to the community and their tolerance, understanding and respect for children and their families, as well and their cultures and ways of being, c) their unstructured approach to learning, and d) their accessibility -- CSWs welcomes everyone, regardless of income, academic achievement, career goals, etc. 

When not at the Greenfield CSW, José enjoys watching, playing, and talking sports, as well as running, hiking, kayak fishing, and coffee...lots of coffee. One of Jose's greatest pleasures is singing with a live Mexican Banda or Mariachi. 

Curt Gabrielson has 25 years of experience teaching science and mathematics with interesting hands-on techniques that involve simple materials and experiences from everyday life.  He has a degree in physics from MIT and is an adjunct faculty at the Exploratorium Teacher Institute in San Francisco California.  Curt has written 5 English books with science and mathematics activities for students and teachers.  He has taught in California, Mexico, India, China and Timor-Leste, always making a close connection between the local culture and the principals of science and mathematics.

Curt was founding director of the Watsonville Environmental Science Workshop for 11 years before he relocated with his family to Timor-Leste, a developing nation in Southeast Asia.  There he worked with the Ministry of Education on national curriculum development and teacher training, and assisted the national university to open a physics department.  In 2019 he returned with his family to central California and began working with the Greenfield Community Science Workshop. He focuses on presenting school-day field trips by classes to the Workshop and professional development with local teachers.

In his spare time he enjoys hiking, climbing and making music.

Omar Vigil is a CSW Technician. He is originally from Mexico City and resides in Watsonville. Omar graduated from California State University, Monterey Bay (Go Otters!). During the week, Omar works as a Housing Coordinator for Housing Choices, an non-profit organization that aims to assist all people especially those with disabilities to attain access to affordable housing. On Saturdays, Omar manages the Science Workshop’s drop-in program and helps orchestrate field trips with the youth. If you are looking for a great place to workout make sure you ask Omar on your next visit to the Science Workshop. He is an extreme gym junkie, film enthusiast and enjoys riding his motorcycle or working on his cars during his spare time.  

Marisela was born in Salinas, a couple miles away from her hometown of Greenfield. Her interest in science stemmed from her family trips to the beach, local aquarium and the natural landscape that surrounds Monterey County. She’s also had the opportunity of exploring the city of Los Angeles, especially the cultural food options it provides. At UCLA, she earned a bachelor’s degree in Biology and Spanish. Marisela is the lead technician for the Science Workshop's Mobile Program. She travels to the surrounding towns of Greenfield to provide kids, just as those in Greenfield, the opportunity to engage in science. On her free time, she enjoys watching movies, reading a book, going on hikes or stress-relieving nature walks

Mónica Aguilar is a CSW Technician. She is a proud daughter of immigrants, self-identified Xicana and resident of Greenfield.  Mónica recently graduated from the University of California, Los Angeles (#onceaBRUINalwaysaBRUIN!). Mónica is the lead technician for the Science Workshop's After School Science, Technology and Engineering program.  She conducts hands-on science activities and science concepts with the students of Greenfield Unified School District's four elementary schools. She has worked with the youth of low-income communities throughout her entire collegiate career and hopes to continue impacting their lives by introducing them to topics that have historically been dismissed to them. Through the privilege of having access to higher education she hopes to positively contribute as much to the issues affecting the wellbeing of Latinx populations. Mónica plans on continuing her education in the near future by pursuing a Masters in Public Health. She enjoys working out, learning about different cultures, trying new foods, taking pictures of her baby nephew and spending quality time with her family and friends.

Aaron Oyoque is a CSW Student Instructor and currently works with the communities of Soledad and San Lucas through our Mobile Program where he helps elementary school children bring their projects to life. He was born in Salinas, CA and is currently attending Hartnell College. Aaron is particularly passionate about youth, and plans to dedicate his professional life to serving them. He loves meeting new people and is known for his patience. On his free time you can find Aaron barbecuing and listening to music or enjoying his favorite thing about South County, Greenfield’s scenery!

Fabian Chacon, widely known as Chacon, is a CSW Student Instructor. He was born in Guadalajara, Jalisco (¡viva Jalisco!). He is currently attending Hartnell College and hopes to transfer to a four year university. He aspires to one day hold a position in government. At the Science Workshop, not only does Fabian help the kids build and create their projects but he is the behind the scenes man for the Mobile Program as he prepares the materials necessary for the projects being conducted during the week.  Fabian’s favorite science moment would be the invention of light since we greatly depend on it on our day to day activities. He is an individual who enjoys skeet shooting, fishing, carpentry and eating steak! 

Juan Salvador Silvestre, also known as Juanito, is a CSW Student Instructor. He was born in Oaxaca, Mexico, and is a trilingual (Triqui, Spanish, and English) student attending Hartnell College. He envisions himself becoming a Sheriff officer. Juan really enjoys working with kids and experimenting with their projects at the science workshop’s drop-in and after school programs. Juan plays in a regional Mexican band as a side hobby (¡shau!). When not at school or at the shop Juan stays fulfilling his physical goals either through running or getting a good work out at the gym.

Elizabeth Acevedo is a CSW Student Assistant attending Greenfield High School. Elizabeth has lived in Greenfield all of her life. She plans to pursue a career in computer science after graduating high school (woo class of 2020!). She is part of the After School Science, Technology, and Engineering program as well as the drop-in program. She is very passionate about her job as it allows her to learn from students as much as they learn from her. Elizabeth is very grateful for the existence of the science workshop as she has seen how much of an impact science can do in the life of a kid.  Aside from liking math and science, Elizabeth is a very physically active individual who enjoys bike rides, working out and spending quality time with those she cares about most.

Alberto Jose Chacon, also known as Chacon (Fabian's little brother, if you did not yet catch on) is a CSW Student Assistant. He is a student at Greenfield High School. Alberto was also born in Guadalajara, Jalisco.  He is part of the drop-in and after school programs. At the shop, he helps kids build just about anything in their imagination.  At the schools, he helps facilitate the project of the week while integrating a science concept. It comes with no surprise that Alberto really enjoys fixing electronics and tinkering with cars and computers. He aspires to one day work for Google or Tesla as a computer science engineer.  Aside from all the tinkering, he enjoys hunting and relaxing.

Omar Jr. Perez is a CSW Student Instructor. He is about to graduate High School this spring and will continue his education at Hartnell Community College. Omar is thinking of pursuing a career in mechanical engineering or carpentry. He is part of the Mobile Program team and can be found at the drop-in program from time to time. He enjoys his job because he gets to assist kids while learning new things himself.  You can always catch Omar at Greenfield’s Patriot Park, wearing an Adidas hoodie, playing soccer! (¡Arriba el Barςa!)

Sabrina Silva is a CSW Student Assistant and is currently a high school senior (go class of 2019!). She plans to continue her education at  Hartnell Community College where she intends to pursue a career in nursing. You can find Sabrina working with the kids at the science workshop’s drop-in program or traveling with our Mobile Program to places like San Ardo and San Lucas. She is fascinated by fire whirls and her favorite science moment is the invention of electricity. She likes that there is a mutual interest in science between her and everyone who comes in to the Science Workshop. Sabrina enjoys a good horror novel, listening to BTS and speaks a little bit of Korean!
