Mr. Healy is a life-long Northwesterner who grew up backpacking and exploring the North Cascades, Olympics, and Washington Coast. Those formative experiences gave him a deep appreciation for the wonders of nature that continue to amaze him to this day.
After graduating from the University of Washington with degrees in Biological Oceanography and Zoology he realized a passion for teaching while in graduate school. This led him to combine his love of nature with a career in science education. Next came a teaching degree from Central Washington University and a Master’s in Science Education and Curriculum from the UW. He taught high school and middle school science in the Renton School District, where he met his wife, fellow science teacher, and love of his life. Later moving to Lake Washington, he’s proud to have helped start and grow the vibrant learning community that is EAS, with its strong parent involvement and students who learn to make a difference in their community!

Teaches: STEM and Algebra
Hello, my name is Marcus Rose and I am a middle school STEM teacher. With over 20 years of teaching experience, I bring many tools to the classroom -- love for the outdoors, how things work and most importantly a strong passion to share this with middle school learners. In addition to teaching STEM classes at the Environmental and Adventure School, I love to build things. Recently, we have been building canoes at school for use at camp and summer trips, but I also love to tinker with bicycles.
I learned to love the outdoors as part of my Biology major at Principia College where many studying abroad opportunities were part of the college culture. I continued learning about plant systems at the University of Missouri for my Master of Science in Alternative Agriculture. After a very short employment at Monsanto, I was able to grow into becoming a seasonal outdoor educator around the United States. During one particular season working for Pacific Crest Outward Bound School, I was encouraged by other instructors to continue my education and become a classroom teacher. I completed a Masters in Teaching at the University of Arkansas and then moved back to Washington. I sought an opportunity to bring expedition style learning to the public schools and I was very grateful to find a new school with the whole staff sharing these environmental and adventure goals.
When I am not working with middle school students, I love to pick a banjo, strum the guitar, work with my cattle dog and have adventures with my family.
Cristina Kollinger Collesei (a.k.a Sra. Kollinger)
Teaches: Spanish 2 - 8th grade
I was born and raised in the Eastern, upper-Amazon area of Ecuador. I learned how to swim in the Tena River, with the river current taking me down as I learned. Nature was all around me and I still stop to notice insects, plants, and fruit hanging on a tree like Christmas ornaments.
I have a Masters in Spanish and French from St. Louis University in St. Louis, MO and a TESOL Certificate from UCI Extension in California. I have lived in many places, including Missouri, California, Illinois, France, Italy and now the gorgeous Northwest. I feel at home with all the green around me and I love how international our area and school is. I have so much to learn from every single student. I love to travel and learn about other cultures and when I am in the classroom, the world comes to me, and I get to take a peek. What a privilege! I hope my students find that learning Spanish, or any other language, can open doors to knowledge, different perspectives and curiosity.
Teaches: Spanish 1 - 7th grade

Once I moved to Riverside County, I found the mountains and spent many weekends exploring them. I am looking forward to learning from this school community, staff, students, and the school’s diverse program.
I enjoy traveling to Mexico every other year to visit family. I am looking to travel to other countries in the years to come. I have been in this beautiful state for a little over a year and love the beautiful outdoors. Some of my interests include crocheting, dancing, exploring, gardening, hiking, photography and traveling. ¡Hasta Luego¡
