Eliza Waugh (Alpha Class)
Eliza loves to be part of a community where creative ideas are free to be explored and where learning is an integrated, joyful, collaborative and encompassing experience.

Her sons, now high school age and beyond, attended AHB and she served several years as a board member, as well. Learning and discovering with children has always been a passion for her. If you’re ever in her classroom for long you’re bound to hear her say, “We are each other’s teachers!” because she believes that children offer insight into living and learning in the moment that demonstrates the true meaning of happiness.
When not at school, Eliza loves to spend her time with her family and pursuing the joys of writing, art, the great outdoors (especially in a kayak or hiking boots), yoga, reading, cooking and being with friends

Kelly Larson (Beta Class)
So much to learn… so much to explore… so many exciting challenges and opportunities. Kelly has felt so lucky to be able to share her curiosity of the world around her with students throughout her teaching career. Kelly received her Master’s in Education from the University of New Hampshire. She has taught in the primary grades in Barrington NH, Albuquerque NM, Salt Lake City UT, Los Alamos NM and finally here in Austin TX as she and her husband raised two boys and her husband pursued a career as a geologist.
Everywhere Kelly has taught, whether public or private schools, small or large communities, she has enjoyed taking children on a path of wonder and excitement about the world we live in. She has investigated forests and fields of milkweed in New Hampshire, and built a garden from scorched earth in Albuquerque. In Los Alamos she created a curriculum for the district to get every child in the school outside at least once a month to marvel at the amazing aspects of nature.
As the Japanese proverb states- to teach is to learn, and there is nothing more amazing than exploring right alongside children. Kelly looks forward to learning and creating memories alongside your children.
Kristen Mazzaferro (Beta Class Assistant)
Kristen grew up just outside Boston, MA and comes from a family of educators! In high school she had dreams of becoming an elementary art teacher, so she took early childhood education classes and worked part time in a kindergarten class. However, these dreams were rivaled by her love of fashion. As college approached she was torn between pursuing her love of working with children by studying to become a teacher, or her love of fashion by studying design.
She chose to study fashion and costume design at Framingham State University but couldn’t give up working with kids, so she worked as a nanny during the summers. After she received her Bachelor of Science in Fashion Design and Retailing her passions amazingly merged as she landed a job at TJX Companies designing clothing for toddlers and girls. During her 7 years at the company, she also sought out volunteer opportunities to work with children, primarily volunteering at children’s community theaters helping to create costumes.
In 2016 she decided to move to Austin and leave the corporate fashion world, focusing instead on growing her own brand and developing her skills as an educator. Finding a place at AHB has been an absolute dream come true. She loves her role as an assistant in the Beta class and being a part of the close knit AHB community. Her favorite part about teaching the Beta students is helping them to discover their talents and strengths and encouraging enthusiasm for learning. She is so excited to grow and learn from the AHB staff and contribute by bringing her creativity and passion for the arts to AHB.
Lindsey Pearlstein(Gamma Class)
Lindsey is absolutely elated to join AHB because of its tight-knit, collaborative community of engaged children, parents, and faculty. From its focus on inquiry-based learning to its pro-social justice stance, AHB is a prime example of the progressive school that Lindsey has been seeking. Education has been her passion for as long as she can remember, as she is dedicated to assisting others towards creating positive change in the world.
Lindsey grew up outside of Boston, Massachusetts and has been working with children for as long as she can remember. In high school, she worked at two Boys & Girls Clubs as a camp counselor and tutor. She also led the Brookline Literacy Partnership, an organization at her high school that promoted literacy in areas without adequate access to literary materials, by building libraries, tutoring, and helping classroom teachers. This spurred her love of literacy and book collecting. She now has over 1,000 books in her classroom library!
When applying to college, Lindsey sought a university with a top-notch College of Education. She decided to attend The University of Texas at Austin and graduated in 2017 with high honors. While there, Lindsey was extremely involved, taking on leadership roles in the Student Government, Education Council, Bridging Disciplines Program, and Alpha Delta Pi sorority. She student taught and taught in AISD before coming to AHB. She has also used education as a means to travel the world and has taught English abroad in Thailand & Guatemala!
Matthew Grey (Gamma Class Assistant)
Matthew earned his BA in Adolescent Education from the College of St Rose in Albany, NY. Over the years, Matthew found himself teaching such varied classes as preschool in Albany, high school in Brooklyn and The Bronx, and elementary school in small town Upstate New York.
In early 2014, Matthew wandered down to Austin, TX in a pursuit of sunshine, friendliness, and tacos. An escape from the cruel winds of winter may have also played a part in his decision to move, but that is a topic of great debate among current Matt scholars. After searching for a way to combine his passion for education with his love of progressivism, Matthew found AHB School and leapt at the chance to join its community.
Matthew’s varied interests include playing music, cooking, gardening, traveling, and reading. He has a ferocious feline named Joose.
Kirsten Coleman (Delta Class)
Kirsten has taught at AHB for over 9 years, serving in various roles as Math Coordinator, Teacher Board Representative and co-teacher in the Beta, Gamma and Delta classes. Her approach to education is that learning to think and applying that thinking to making decisions is the most important and exciting thing one can do. She is always striving to find the intersection of the subject knowledge and its application. Since 2001, Kirsten has coached various teams in Math Pentathlon, Destination Imagination, Math Olympiad, and the Stock Market Game. She also tutors students in reading, writing, science & math. In what turned out to be a fun experiment, Kirsten started, directed and taught in a small private middle school located in Austin for one year. Prior to teaching children, Kirsten worked for high-tech firms on the East and West coasts. In that world she held various technical, educational, consulting and management positions and enjoyed them all. The job which helps guide her current teaching approach was one in which she was an intermediary between executive management, sales personnel and programmers, getting to travel the world seeing different industries, cultures, and types of jobs. Kirsten is a graduate of Earlham College, a small liberal arts Quaker School in Richmond, Indiana where she majored in Sociology and Anthropology and spent a semester and summer in Spain. Kirsten has also enjoyed volunteering as a Big Sister, at Heifer International, for the Girl Scouts, and for various animal rescue league outreach programs to the elderly.

Alice Elder (Delta Class)
Alice is a native Austinite who grew up in Hancock neighborhood. In 2003 she received her B.A. with Honors in anthropology from the University of Texas at Austin. Alice then went on to pursue graduate studies in anthropological sciences at Stony Brook University in New York, where she completed her M.A. in 2006 and her Ph.D. in 2013. In the course of her doctoral studies, Alice spent almost two and a half years collecting behavioral, ecological, and nutritional data from wild groups of agile gibbons, siamangs, and mitered langurs in Bukit Barisan Selatan National Park, Sumatra, Indonesia. This long-term fieldwork culminated in her dissertation: Competition among three primate species at Way Canguk, Sumatra, Indonesia. While entering and analyzing data, and writing her dissertation, Alice worked as a substitute teacher in the Austin Independent School District. From 2011 to 2015, she gained experience in the instruction of elementary and secondary students in general and special education settings. In the Fall of 2013 Alice took on the challenge of being a long-term substitute teacher for a vibrant class of second graders at Maplewood Elementary School.
Alice is currently working on her alternative certification through the TEACH Quest program to teach science for grades 4-8. When she is not educating herself or others, Alice spends her time exercising outdoors, gardening, cooking, or folding origami. She is very active in local USTA leagues and tournaments as a singles tennis player. Alice is also the proud mother of an abundantly fluffy cat, who she named after her hometown when missing it terribly in cold, cold New York.
Alice perceives learning as an active process that is constructed by building upon previous knowledge and aided through guided discovery, whereby teachers model and facilitate this process. She feels that curricula should be based in real-world contexts likely to be relevant to student’s global reality. Thus, Alice is excited to join the team at AHB Community School, where she hopes to flex and grow her teaching skills in a dynamic, progressive learning environment.
