This past May I graduated with a bachelor's of science in K-8 special education and a minor in coaching from The University of Maine at Farmington. At Farmington, I graduated with multiple semesters on the Dean’s list. Outside of school, I love to be outside. Some of my favorite things to do are playing sports such as golf, basketball, and hiking. I love playing sports, especially golf. It is a mental game that challenges you on every hole. I like to play at different courses and collect their monogram golf balls for my display case. My favorite time to hike is early in the morning. During the winter, I enjoy relaxing at home watching Sunday football with my family and playing basketball with my friends. This year I am excited to begin my teaching career and learn from my colleagues and establish relationships with students in the upper grades.

She continues to be an avid skier and enjoys time on the hill with her husband, Greg, and two children, Vincent and Libby. During the four months that snow isn’t covering the ground, you can find Jane cheering at baseball and soccer games, coaching Girls on the Run/Girls on Track, weeding her gardens, playing tennis and, of course, reading a good book.

David Green-Leibovitz


About David coming soon!

Ross Greene

Physical Education/Health

I am a K-12 certified Physical Education teacher and have been teaching K-6 P.E. since 2015. My educational background includes a B.A. in Psychology from Dickinson College in Carlisle, Pennsylvania and completion of the Teacher Apprenticeship Program (TAP) with an endorsement in Physical Education through Champlain College. While enrolled in TAP, I was awarded the Excellence Award for Outstanding Teaching. This award is given to the aspiring teacher that demonstrates best practices and pedagogy among all TAP students.

I believe P.E. is a great place to learn skills, movements and strategies of course, but also lifelong skills like cooperation, sportsmanship and perseverance. The skills, movements and strategies students learn will put them on the path toward physical literacy. The lifelong skills will help students be the best they can be not just in elementary school, but far beyond. It is my goal to teach each student how to become physically literate, but also to help each student lead a physically active lifestyle.

Personally I enjoy all sorts of different physical activities, but I particularly enjoy skiing, biking, and playing tennis. When I was in grade school, I played a variety of organized sports including soccer, basketball, tennis and track. Even after organized sports, I was always doing something active. You could find me playing roller-hockey, wiffleball, table tennis, or biking. I have always enjoyed competing for the fun of it as well as for the social aspect. I have always enjoyed being active and I attribute this to all the great memories I had as a child participating in organized sports, playing pickup games with kids in my neighborhood, having new experiences at summer camp and trying to keep up and compete with my older brothers.

My goal for the P.E. program is to provide the students of The Warren School positive experiences in P.E. class and to build the foundation of the necessary skills to lead an active and healthy lifestyle. I hope to create lifelong movers promote this lifestyle in and out of school.
