Clara Ashwood

Young 5s & Kindergarten Teacher
cashwood@summers-knoll.org

I am an educator of young scholars with a background of 21 years experience in Preschool and Kindergarten. I have an Elementary Education degree from University of Wisconsin-Madison and a certificate of Education Leadership from Capella University. I have been at Summers-Knoll School for five years. When first visiting Summers-Knoll, my initial thought was that I wanted to teach here because I wished I could have been a Summers-Knoll student. I would have loved it.

I have specific experience teaching Kindergarten in project-based schools, having spent 8 years at Tesseract School and Minnesota Excellence in Learning Academy. At Tesseract School I gained exposure in implementing a project-based approach to education within a team of Kindergarten and First grade teachers. At Minnesota Excellence in Learning Academy I led in creating the Math Curriculum and Personalized Learning Plan program for Kindergarten.

I live in Ann Arbor with my fiancé Matt. I love to run long distance races, bake bread, dance, and travel. This October I’ll be running the Detroit half marathon.

I draw inspiration from the young children to continue to be creative and explorers of the world. I am passionate about sharing to others the importance of the young child.

Karen Bayoneto

Director of Operations
kbayoneto@summers-knoll.org

As the Director of Operations I have overseen the day to day operations of Summers-Knoll since January 2009 and admissions and enrollment since 2017. The position is very rewarding for me because it allows me to work with not only the staff, but our students, parents and prospective parents daily. After graduating with my Bachelor of Science degree in Finance from the University of Michigan, I spent many years working in healthcare finance before joining the team at SK. I have two children, a Wolverine and a Spartan that are both alumni of SK.

Eddie Carrillo

Upper School Co-Teacher
ecarrillo@summers-knoll.org

Eddie relocated to Ann Arbor shortly after graduating from The University of Texas at El Paso in 2021. He earned a BS in Biological Sciences with a concentration in Ecology and Evolution. As an undergraduate, Eddie conducted research in education improvement in the biological sciences department. He primarily worked with qualitative data to discover correlations between how instructors speak to students and the affects it has on student outcomes. He has collaborated with multiple Universities such as the University of Georgia, the University of Minnesota Twin Cities, and the University of UC Davis. When Eddie has free time, he enjoys going to the gym, reading books, walking through Ann Arbor’s beautiful parks, trying new foods, and nerding out on some video games/comic books.

Eddie started as a teacher assistant for the middle school at Summers-Knoll and will now be an associate teacher for the 2022-2023 school year for the 7th/8th-grade class. Eddie will lead the Summers-Knoll Chess Club and looks forward to participating in the Washtenaw Elementary Science Olympiad team once again. From his research and teaching experiences, Eddie has learned how important it is to conceptualize material for students and believes Summers-Knoll grants the freedom for students and teachers to make those connections. Eddie focuses on meeting the specific needs of each student and strives to create a comfortable environment to allow students to take ask questions and take risks. Eddie enjoys the opportunity that students have at SK to express their creativity and build on the real-world skills that they will use throughout their lives.

Colin Coviello

Music Teacher
ccoviello@summers-knoll.org

Colin is very excited for his second year as the music teacher at Summers-Knoll! He recently moved to Michigan with his wife, Ashani, who is in a graduate program at the University of Michigan. Colin is a recent music education graduate with a passion for all things music. Colin began studying and performing music at a young age when he began violin lessons at 3 years old. Having grown up in a musical household, there was never a time when Colin was not involved in some musical activity. Colin inherited a love for music education from his mother, who is a choral director. He has performed in orchestras, choirs, and musical theater productions which has given him an appreciation for the broad and diverse field of music. Colin believes there is a place for music in everyone’s life, whether it be listening, performing, creating, or teaching. As a teacher, Colin wants to foster curiosity and appreciation for music no matter what interest his students have. Colin strives to show his students the beautiful and complex art form that is music, and make sure to have some fun along the way.

Aristea Fulcher

Classroom Assistant
afulcher@summers-knoll.org

I am a Preschool Assistant at Summers-Knoll and a SK alumnus. Even when attending Summers-Knoll in middle school I knew it was a special place. I’ve always loved how community-focused the school is, and I am so excited to be able to rejoin this community. It has been amazing to get the opportunity to revisit my old school and see how they’ve continued to improve it. While most schools and school plans haven’t changed for years, Summers-Knoll is constantly changing and evolving to make sure it’s the best version of itself for the student body. I spent several years tutoring and babysitting before working at the school, which ignited my love of teaching and spending time with children. I love getting their perspective of the world, even though they assume I am 55 and have children. No one sees the world quite like a kid. I’m interested in pursuing a career in teaching, but for the time being I’ve been enjoying just spending time with the kids, telling stories, making crafts, and playing games. I enjoy playing guitar, reading, and playing Dungeons and Dragons with my friends in my free time. I love animals and am a pescatarian and cat owner. I have two cats, one which my friend theorizes is stuffed with bean bag filling and the other which is named Rocket Ship. My Favorite color is periwinkle, mostly because I think the name is funny. The color is pretty too though.

Imogen Giles

French and Latin Teacher
igiles@summers-knoll.org


I am the Languages teacher at Summers-Knoll and have been an SK faculty member for over a decade. I teach Latin to every class from Preschool to 8th grade and French from 1st to 8th grade. This role in our school life means I am known as Magistra and as Madame, and I consider myself very fortunate to have had the opportunity to begin a Latin program for the School when I was first appointed to transform what was a small French program to one that embraces all our students.

I gained my Bachelor of Arts and Master of Arts degrees from the University of London in England. I taught in a number of independent schools before becoming the Head of Classics at Cobham Hall School in Kent and then moving to this country.

I am an ardent reader and love classical music, ballet, drawing, and painting. I also love to travel and look forward to spending each Summer with my family in our home in France.

Thea Givens

Classroom Assistant
tgivens@summers-knoll.org

I began at Summers-Knoll two years ago as a classroom assistant and aftercare attendant for the Young 5s and Kindergarten class. I’ve grown up in the Ann Arbor area and have forayed in my personal and academic learning into foreign language (French, Japanese, Spanish), global cultures, and various slices of biology such as medical science, native plants and trees. Anything that has to do with humans or the natural world will often pique my interest. I’m very excited to be working at a school with a Project-Based Learning curriculum. I hope to somehow transmit my zeal for knowledge to those I work with at Summers-Knoll.

Barbara Hohmann

1st/2nd Grade Teacher
bhohmann@summers-knoll.org

Hello, my name is Barbara Hohmann. I am a First and Second grade teacher at Summers-Knoll. This is my sixth year at Summers-Knoll, first as a parent, then as a substitute, and then lead teacher. I am a passionate, creative person and always work hard to do my best.

I was raised in Okinawa until I was 10 years old and then my family moved to New Smyrna Bleach, Florida. I feel the relationships that I have formed throughout my life are powerful and have shaped who I am. Given this, teaching is some of the most important work I can do. Through human connection, I believe that we have the ability to cause change.

Over the past 20 years I have taught and learned from young people as a camp counselor, public school teacher, children’s shelter counselor and teacher, Waldorf teacher, museum educator, art teacher, and mother. I have a Bachelor’s degree in Fine Arts and a Masters in Education and Arts Administration, both from Florida State University. I also have a degree in Surface Design from the Fashion Institute of Technology in New York City, and a Waldorf teaching certificate from the Waldorf Institute of SouthEast Michigan.

When I am not teaching I enjoy my wonderful family. My partner and two children keep me busy, rock climbing, surfing, fishing and going on adventures. I love the ocean, plants and creating things.

Erika was born and raised in Ann Arbor and earned two bachelor’s degrees (Cultural Anthropology and Environmental Studies) at the University of Michigan. She has been teaching in the San Francisco Bay Area for the past 23 years and is thrilled to part of the SK community. Her teaching career began in outdoor/environmental education, where students regularly asked her, “Why can’t school always be like this?” This question drove her to get her teaching credential and devote the next 15 years to bringing thematically integrated, hands-on, project-based learning to grades 1-6 in both public and private schools. In addition, Erika spent two years teaching and writing curriculum for the education department at The Lawrence Hall of Science.

Erika’s passion is science, and thus, it has been the main through line in her career. Her hobbies are hiking, birding, traveling, reading, gardening, and dancing.

Mary Perrin

Art Teacher
mperrin@summers-knoll.org

This is my 8th year at Summers-Knoll. My BFA is from EMU, and my skill base in the arts is wide, varied, and always growing. I currently work with an artist’s collective based in Detroit, building themed vehicles, sets, and activities for creative events.

Though I am working towards becoming a certified teacher, I believe my background in the “real world” of Art, as opposed to arts education, is one of the strengths I bring to the school. Many things can only be learned through doing, and I have a lifetime of experience being an artist, working with other artists, and presenting my art to the public. My goal is to teach your children how to teach themselves art so they can continue to learn and grow as artists and creative thinkers long after they leave my classroom.

Learning Specialist
mswain@summers-knoll.org

I am the Learning Specialist at Summers-Knoll and have been here for 10 years. My Masters Degree is in Special Education from Eastern Michigan University, and my Bachelors is from the University of Michigan. I attended the Residential College, and graduated with a concentration in Latin American Studies.

I have been an educator for 40 years.I started my teaching career as a Teacher Consultant and after 7 years, I moved into the regular education classroom, where I taught 3-5th grade. I enjoyed teaching in a small school district and community.

I worked privately before coming to Summers-Knoll and many of my referrals were for students struggling in reading. Because of that, I sought out more information on dyslexia and took various reading remediation trainings including Orton-Gillingham and FAST Reading. I am thrilled to be here at Summers-Knoll and appreciate the collaborative spirit here.

I love to travel, read and learn, and spend time with friends and family. Pre-covid much of my time was spent in social justice settings. I hope to return to that sometime soon.

As the Executive Director of Teaching & Learning at Summers-Knoll (SK), I work with SK teachers to design standards-aligned, project-based instruction that fosters students’ creativity, curiosity, and compassion for others. My long-term goal is to co-construct systematic, sustainable structures that support SK teachers’ curriculum development, instruction, and continual professional growth.

Before joining SK, I was an elementary classroom teacher for ten years (six at a public school in Denver, Colorado, and four at a PreK-12 independent school in Watsonville, California). After earning my PhD in Educational Studies at the University of Michigan, Ann Arbor, I joined the faculty in the Department of Teacher Education at Michigan State University in East Lansing for seven years, where I taught undergraduate and graduate courses in literacy methods, action research, and multilingual learners’ language development across content areas.

Alongside my work in education, I enjoy cycling, practicing yoga, spending time with my spouse and two cats, and traveling.

Valerie has been a presenter at the Michigan Association for the Education of Young Children’s Conference (MiAEYC) in Grand Rapids, Michigan on several occasions. She wrote her curriculum, “Andy Warhol Can, Can You?” as a reflection of the actual activities and principles she has applied in her own classrooms throughout her career. She gives tangible examples of how even the most hesitant, “I can’t draw a stick figure” teacher can incorporate art into their Early Education environment (birth-8 years) and across all domains of the learning environment.

Valerie has been married to hubby Jonathan for 39 years and is the proud mom of 4 grown children. All are artistic in their own way and most are educators! She is an even prouder Grandmother to two sets of twins who she spends evenings with just about every single day.
