Ms. Susie is beginning her 2nd year at Rising Sun Montessori, as a Primary teacher (Guide). She has a Master of Arts in Education and is finalizing the Montessori certificate for Primary. She has three years’ experience teaching in a Montessori classroom and is in her tenth year of teaching in a public-school setting. Before that, while her own children were growing up, she was an instructional aide for 14 years in a rural school in the California foothills above Fresno, working in all grades from K to 8th and Special Ed.
Susie has a strong interest in the arts and has engaged in many different art forms from clay, weaving, all things fiber, and many more artistic endeavors. Her dream for this year is to bring as many art experiences as possible to the Sunflower students. She believes art, music, and the Montessori Method give children the chance to express themselves in a way that supports self-esteem and sense of autonomy; something that is so important for a growing child.
Susie has a fiber workshop at her house where she spends hours weaving, knitting, felting, and sewing. She also loves to travel and has been to Chile, Peru, and Spain. Her daughter, Sophie, is a mediator in the fall, winter, and spring months and runs trail crews in the high Sierras in the summer. Susie’s son, Eli, lives in New York City and works as a comedy writer, with SNL on his resume. They are 9th and 10th generation Californians, whose ancestor walked with Father Serra into Alta-California as a foot soldier.
Susie is excited about being back in a primary classroom. She has a deep love and respect for the Montessori approach and believes it is THE key to raising a well-balance individual who knows how to successfully meet the challenges of today’s world. She looks forward to this new school year and all the amazing times with the students.
