Molly MacDonald, Early Childhood Teacher  Molly Mac Donald  

Molly is the oldest of seven children and has been working with children since those first days of babysitting the little ones.  She began her formal teaching working with young children with significant disabilities in 1992 and continued that work for eight years.  It was at this time that she was introduced to Waldorf education and began to look deeper and explore.  In search of Waldorf for her own young children, she started a parent child class with a friend and continued that work for two years.  She then taught Handwork for a year and found herself pulled to River Valley where she began assisting in the Kindergarten.  She is excited now, to be returning to parent-child work this year and has begun her Waldorf Early Childhood training at Sophia’s BHearth in Keene, NH.

“Waldorf Education receives each child, with love, on their path toward growth and independent human development.  It allows both the time and space for each individual to unfold and shine, at their own pace, while providing just the right amount of imagination, creativity and inspiration.”

Christina HummelChristina Hummel, Class of 2023

Christina Hummel knew when she was six years old that she wanted to be either a teacher or a doctor. Christina attended a Waldorf School in Germany from kindergarten through grade five and then a public school on a Greek island from grades six through twelve. As she began thinking about college applications and what she might like to be, it became clear which of her two dream professions she wanted to pursue. She wanted to be a teacher and specifically a Waldorf teacher. Having received her Certification in Early Childhood from Sunbridge Institute, Christina did her practicum at the Merriconeag Waldorf School. She joined River Valley in 1998 as one of its first two kindergarten teachers, moving into the grades in 2001 while pursuing her certification in Elementary Education from Antioch New England. Christina loves morning runs with her dog, getting together with friends, and learning a new language – though she has discovered it doesn’t come as easily as it once did.

“I wanted to be able to give children the wonderful gifts and experience my Waldorf education had given me. I love the notion of being with a class for eight years and truly knowing them—caring for them at each stage of their development and seeing them grow into adulthood. I love being their guide though the grades.”

Melanie completed her Waldorf teacher training in Waldorf elementary and early childhood education at Antioch New England Graduate School in 2006 and also holds a BS from Pennsylvania State University. She enjoys dancing in any form—especially African Dance & Contra. Otherwise, her children and her chickens bring her her greatest joys.

“The secret of education lies in respecting the pupil. It is not for you to choose what he shall know, what he shall do. It is chosen and foreordained and he only holds the key to his own secret.”  – Ralph Waldo Emerson

Annie Porter, Class of 2019, Pedagogical ChairAnnie's preference 2017

Annie Porter found Waldorf education twenty-five years ago as a parent, and was fortunate to be part of both the Hartsbrook and Princeton Waldorf School communities, as well as River Valley. Annie received her undergraduate degree in Art History from Smith College and went on to receive both her Waldorf teaching certification and her MA in education from Sunbridge Institute. Her three children are Waldorf graduates. She loves being outdoors, tending her garden and beehives, hiking and sailing off the coast of Maine. She loves a good book. She loves having time to write and she cares about local community development, and supporting the efforts of artists and farmers.

“I believe that Waldorf education functions as a social movement that meets the needs of today’s children, many of whom are growing up in a culture that pulls them out of their childhood. Children are often disconnected from real experiences of work, nature, and art. As a Waldorf teacher, I enjoy working every day to give children an experience of the tangible sensory world, and a sense of the dignity of the human being.”

Lynn VazquezLynn Vazquez, Educational Support Teacher

Lynn began teaching at RVWS in September of 2005. Prior to that she taught at a Waldorf initiative in Wilton, CT and served as a class teacher at the Vancouver Waldorf School in North Vancouver, British Columbia. Before receiving her certification in Waldorf Education, Lynn taught mathematics to seventh and eighth grade students in an inner city public school in New York State. She received her Bachelor of Arts in History and Mathematics from Binghamton University and her Master of Science in Remedial Education from Sunbridge College. Lynn has been teaching for the past 21 years and delights in learning. Recently she became certified as an Orton-Gillingham reading specialist and has taken several courses in preparation for HANDLE screener certification.

While at RVWS Lynn has served as a class teacher and is currently enjoying her role as an educational support teacher, as she has always been interested in individual differences and the different learner. She believes that Waldorf education encourages children to celebrate their unique gifts and talents and teaches students to honor their peer’s differences.

“Inspired by many of my teachers, I believe that Waldorf education enthuses, inspires and elicits compassion for others. The curriculum addresses the needs of the child at each stage of development and uses an experiential and artistic approach to teaching academics in a collaborative learning environment.”

Cindy Schretlen

Cindy Schretlen, Director of Admissions and School Life

Cindy joined River Valley Waldorf School first as a parent in 2000, when her children were small. The more she learned about Waldorf education through workshops, speakers and volunteering at the school, the more deeply she came to value what it offers children and their families. Cindy has been serving as Admissions Coordinator since 2001 and is a past member of the College of Teachers.

Outside of RVWS, Cindy enjoys gardening, cooking, reading, yoga, spending time with family and dear friends, and is seriously considering getting back on her bicycle.

“I first bumped into Waldorf education when my oldest son was a toddler; the more I researched and read about it, the more it just made so much sense! I decided at that time if there was any way for my children to be educated in a Waldorf school – that was what I wanted. I was not disappointed. Introducing new families to Waldorf education remains one of my favorite things to do.”


Reeve Kelly, Business Administrator

Reeve’s professional background is entrepreneurial, providing business consulting for public schools. She first became interested in alternatives to the traditional educational model during her work at Hurricane Island Outward Bound School in Rockland Maine. She received her BA in English Literature from Rutgers University. After graduating, she worked with public schools to manage the business side, and eventually co-founded a software start-up. Throughout that time, she sought a different experience for her own young children, eventually learning about Waldorf education and River Valley Waldorf School from a family friend. Enrolling her children at River Valley Waldorf School is the best decision she has made as a parent.


Lynne Allbaugh, Buildings and Grounds Coordinator

Charlene Chapman, Bookkeeper

Robbie Miller, Administrative AssistantRobbie Miller

Robbie grew up outside of Philadelphia and received a BA in journalism from New York University. She lived in New Mexico for many years during which time her sister was one of the founders of Golden Circle Kindergarten and, in fact, her niece and nephews were among its first kindergarteners. On a bulletin board in New Mexico, Robbie saw a notice for a watercolor painting class and when she went to the first class she found out that the teacher had studied painting at the Goetheanum. The teacher used Rudolf Steiner’s color exercises and the first three classes focused on the color yellow; the fourth class introduced golden yellow. Robbie felt right at home and thus began her journey with Waldorf Education and Anthroposophy. On frequent visits home she visited Golden Circle and after she moved back to Pennsylvania, was asked to join the River Valley Waldorf School Board of Trustees in 1999. Her relationship with the school has grown deeper as the years have progressed.

“When I went to the graduation of the Santa Fe Waldorf School and heard the teacher describe his relationship with his class and saw the students speak and perform, I was extremely moved by their confidence and self-awareness. I thought, if I had graduated from a Waldorf school what a different person I would have been at that age! That’s what convinced me of the value of Waldorf Education.”
