Jackson Vanover
Motivated by the coastal redwoods and the sight of the Pacific Ocean, Jackson Vanover chose to attend the University of California at Santa Cruz. Thanks to the early inspiration provided by a stellar calculus teacher in high school, he went on to receive a degree in Computational Mathematics. Three years spent with an outdoor education program for kids in Davis, California has given him both a knack for working with youth and a love for teaching. Now out of college, Jackson is thrilled to be putting his love for math and his passion for education to good use. He hopes to allay the oft-held fear that mathematics is pointless drudgery by providing context, encouraging discovery, and just generally geeking out.
When he’s not in the office, Jackson can be found in his makeshift recording studio tracking vocals, laying down drums, tuning guitars, or putting the finishing touches on his latest piece of music.
























Austin Lim

Austin Lim recently graduated with highest honors from UC Davis, where he earned a B.A. in English and a minor in art history.

Wherever he’s placed, he enjoys seeing how texts (i.e. everything we write, read, and interpret) can be tweaked to promote  communication and encourage curiosity. He’s currently considering a career in education and is excited to explore new ideas with the students he tutors.

Austin is fascinated by peculiar words, Victorian fiction, and pop music. He paints; he reads; he crafts. Right now, he’s also trying to get back into rock climbing after a hiatus of a few years.

Zachary Hutkin
Zachary Hutkin is a 5th year Astrophysics student at the University of California, Berkeley.  He hopes to graduate this semester.  Zachary decided to study Physics because of his love of Einstein and his propensity for trying to explain the world around him.  After two years he changed majors to Astrophysics because of its focus on relativity, a subject he is extremely passionate about.
Zachary struggled a great deal transitioning from the “plug-and-chug” emphasis of K-12 schools to the theoretical and conceptual focus of science at the college level.  He is excited to pass on what he has learned to aspiring science and math majors so that they can transition more smoothly and with less stress.  He tutored several of his peers during high school and college and he is very confident in his ability to tailor an explanation of a concept to any student.
Zachary is a die-hard Chargers fan and loves to play to football, soccer, and tennis with friends.  He has played and refereed soccer for most of his life and hopes some day to coach.

Katie Siembieda is a Fairfax native and Drake High School graduate. She received her Bachelor’s in Environmental Studies and Conservation Biology at UCSC. While studying there, Katie became an intern for UCSC staff and professors working on a USDA-funded project that measured the efficacy of organic pest and soil disease management in organic strawberry farms in Watsonville. This internship helped foster Katie’s passion in studying how individual organisms and species in ecosystems function and affect each other in multitudes of ways, as well as inspired her senior thesis, which investigated the role of insectivorous birds as pest control in various farming ecosystems.

Since moving back to Marin, Katie has started to volunteer at Wildcare Bay Area; helping to rescue, nurture, and eventually release wild animals who have been orphaned or injured. She enjoys reading nonfiction books on animal behavior (especially crows, ravens, and scrub jays), evolutionary theory, and taxonomy. Aside from her passion for wildlife, Katie is an obsessed Giants fan, and can often be found discussing baseball on Reddit forums for hours, or stalking all of her favorite Giants players on Instagram.

As a Sage tutor, Katie loves helping kids realize how creativity and imagination can apply to the sciences, while helping students find learning methods that work for their unique personalities. Katie works well with students with attention-deficit problems to help them minimize distraction and approach organization and learning in a way that encourages them to embrace their unique learning styles, and not feel hindered by them.
