Meet Our Staff

Ms. Becky Grinnell: Primary Lead

I am a proud Michigan native, born in Flint and raised in Flushing. After spending
15 years in the Lansing area, I am now based in Howell and am excited to join the
Stepping Stones Montessori community as a Primary Lead.

I hold an Early Childhood Credential from the American Montessori Society and a
Bachelor of Marketing Management from Northwood University. With four years
of experience in an authentic Montessori school, including two years as a
Primary Lead Teacher, I bring a deep passion for guiding and inspiring young
learners. My background in human resources enriches my ability to build strong
teams and communities, but my focus and love remain centered on supporting
children’s growth.

As a dedicated educator, I am committed to nurturing dynamic and supportive
classroom environments. I strive to help every child reach their potential by:
– Crafting and implementing age-appropriate lesson plans
- Building vibrant, inclusive classroom communities
– Supporting young learners with individualized attention and positive
guidance
- Maintaining open, collaborative communication with families and
colleagues

Outside of my professional life, I cherish traveling and sharing adventures with
my husband and two children, Rylan (11) and Regan (9). Whether we are
exploring new places or enjoying simple moments together, I love creating lasting
memories through discovery, togetherness, and family experiences.

Ms. Mandi Kaufmann: Upper Elementary Lead

I have been the Lead Guide in the Upper Elementary at Stepping Stones since the fall of 2013.  I received my Bachelor’s degree in elementary education from Goshen College in Goshen, IN. I taught 4th grade in North Carolina for 4 years and then traveled and taught in different capacities in Indiana, South Korea, and Virginia.  I’m so happy I found Montessori and this school. I completed my Montessori training for Elementary 1 and 2 from the Midwest Montessori Teacher Training Center in Illinois. My family includes my husband, Lane, 4 year 4-year-old daughter, Emri, and 1 year 1-year-old Avett. We enjoy spending time outdoors, including canoeing, camping, biking, hiking, and gardening. I love to read and crochet when I have the time.  

Ms. Alex DiTrapani: Lower Elementary Lead

I have been working at Stepping Stones since the fall of 2016.  I started as a substitute teacher and ran the elementary after-school program.  The following year, I became the Lower Elementary assistant, a position I held for two years.  After finishing my Elementary 6-9  Montessori training at Waterford Montessori Academy, I accepted my current position as the Lower. Elementary lead guide.  I also hold a Bachelor’s degree in Elementary Education with a focus in language arts from Michigan State University.  Before discovering Montessori, I was a Kindergarten teacher at Belding Public Schools.    

I feel thankful to have found Montessori and such a great school to practice this teaching philosophy!  I am excited and optimistic about the possibilities this school year holds!

I live in East Lansing with my sister Danni.  We enjoy exercising together, spending time with mutual friends, and visiting our parents and their dog in our hometown of Spring Lake. In my free time, I enjoy hiking, baking/cooking, reading, and exploring new places.

Wendy Sylvester-Rowan: Art Lead

I am originally from Philadelphia, PA, and I completed my Bachelor of Science in Art Education from Miami University in Ohio.  I have taught elementary through middle school art in public and private schools in Indiana, Michigan, Hawaii, and Germany, and have been at Stepping Stones for over ten years. I teach art to the elders in the primary program as well as to the children in the elementary classroom.  My husband and I have two children (both of whom attended Stepping Stones!) and two rescue dogs.  I enjoy the arts, traveling, and hiking.
