Meet Upper School Science Teacher Mitch Thomsen

Mr. Thomsen working in the gardens with studentsWhen and how did you first come to MPA?
August 1991. I had moved back to Minnesota in 1989, got married and taught for a year at St. Bernard’s school in St. Paul. I wanted to make a change and interviewed at MPA and St. Thomas Academy. I was offered a job at both schools. I really liked the atmosphere at MPA, knew Chris Jensen, and felt that MPA was the best place for me.

What memories do you have of your first days at MPA?
The joyful return of the students at Back to School Night. Camille Wainwright doing interesting demos in chemistry. Chris Jensen keeping the biology classes moving. I remember feeling that I was in a “fast” crowd. Here, at MPA, all the faculty were very talented and hard-working. The goal is creative, student-involved education and everyone, everywhere was doing this. The school was alive with positive action. I felt I needed to “raise my game” if I was going to be an effective part of this hard-charging group. There was such a collegial feeling between all the teachers. The male teachers had to wear a shirt and tie. This is where I started my biology tie collection. Mostly I was quiet and I listened. There was a lot to learn.

What’s the best thing about being a teacher at MPA?
I have the freedom to do what is best for my students. I can explore new ideas with colleagues and come up with interesting things for myself and the students to do. I can bring in new best practices and keep my classes current with what is happening in the world now. I can use the garden area as an ongoing research resource. I have connections with Ramsey Washington Metro Water Shed District and their expertise and support has been critical to the success of the rainwater gardens at school. I have the support of the administration and they have been instrumental in encouraging me to be involved in the garden, new classes, and new technologies. I have a wonderful relationship with my fellow science teachers. Every day is like a department meeting as we talk and share new ideas, and activities in a very collegial setting. We work together well as a team and we support and help each other. Read More


Meet The Peterson Family

The Peterson FamilyMiddle School math teacher Chris Peterson has been a teacher at MPA for eight years, but became a parent to an MPA Panther himself this school year!

What’s the best thing about being part of the MPA community?
The people. It is a great feeling coming to a school where I know I have colleagues I can count on, families who are involved, and students who are engaged with their academics.

What is your favorite MPA tradition or event?
There are a lot to choose from, but I really enjoy going on the fifth and sixth grade canoeing trip.

In what ways has MPA prepared your child for life in the 21st century? 
From an early age, teachers work with students to be independent and think for themselves. Students have to learn how to work independently and with other students of different ability levels and personality types.

Complete this sentence:
MPA teaches my child: How to be independent, work with their peers while also learning, and how to be respectful to one another.

What advice do you have for another family considering MPA?
MPA accepts students for who they are and works with them where they are at. If you want a school that focuses on the whole child, choose MPA.


Please Welcome Jay Dean to MPA Permanently!

What position will you be holding at MPA?
Assistant Upper School director

From what school/organization are you coming?
The Blake School

Tell us a little bit about your education and past experience.
I earned my B.S. in Producing for Electronic Media from Syracuse University and earned my M.A. in School Counseling from Loyola Marymount University. My teaching and administrative experience includes time at The Crossroads School for Arts & Sciences in Santa Monica, California (2002-11) and The Blake School (2011-22). At Blake, I served as Middle School director for five years. I also served in the interim assistant Upper School director role here at MPA during the 2022-23 school year.

What did you find appealing about MPA during the interview process?
What initially drew me to MPA is the focus on the whole child, its progressive approach to teaching and learning, and the recognition of the importance of social-emotional learning and DEIJ work. After being here for nearly a year, what keeps me at MPA are the people. I have deeply enjoyed my experience working with the talented and dedicated teachers and our curious, creative (and often hilarious!) students. I want to spend more time with them here!! MPA is a “transformative” partner for students and families, and I am excited to continue being a part of that. Read More


Meet Lower School Art Teacher Ellen Scharfenberg

Ellen ScharfenbergHow long have you taught at MPA?
I came to MPA in the fall of 2021. I was looking to move back to the Twin Cities area after having taught elementary art in rural Wisconsin for four years to be close to my family.

What’s the best thing about being a teacher at MPA?
I think the best thing about being a teacher at MPA is the wonderful people that I get to work with. Not only are the faculty and staff at MPA truly amazing teachers and professionals, but some of my closest friends.

Describe your typical day. 
My typical day at MPA begins with prepping art materials for my classes that morning and probably talking to Ms. Mastel across the hallway. I usually teach three Lower School classes in the morning, followed by a great lunch by our Sage staff. I always try to take time to eat and connect with my colleagues. After lunch, I either help with Lower School lunch or recess and teach two more afternoon classes.

Do you have a favorite lesson to teach?
I think that one of my absolute favorite lessons to teach is the second grade fall cabin project. This lesson is a great way for second graders to practice using a one-point perspective and learn about the other elements of art such as space, overlapping, and making objects smaller as they get farther away.

Meet The Goetzke Family

The Goetzke FamilyPeyton started school at MPA in 2020 for her Kindergarten year, and Rowen began her Kindergarten year in 2023. Ashley has worked at MPA since 2016.

What do you love about MPA?
We love MPA for many reasons, but the one that rises to the top would be the encouraging environment for Peyton. It’s been amazing how fast her teachers get to know the ins and outs of how her little mind works. The care and compassion they show to her from day one is truly special.

How does MPA inspire students who dream big and do right?
The character development that happens at MPA is so impactful. Students are not only inspired to dream big and do right, they also see it happening around them on campus. They witness this with their peers, teachers, and the older students they see in the hallway. This is the beauty of a PreK-12 campus. Read More


Welcome To MPA, Samantha Sanchez!

Samantha Sanchez

What position will you be holding at MPA?
Assistant Director of Diversity, Equity, and Belonging

From what school/organization are you coming?
I worked at a very small community college in New Jersey and am completing my Master’s degree at NYU.

Tell us a little bit about your education and past experience.
I received my Bachelor’s degree in Black Studies from the University of California, Santa Barbara and led efforts in higher education reform to increase access and the holistic achievement of minoritized students, which began my professional career in both DEIB and education. After working in K-12 with neurodiverse students and for a private corporation leading community empowerment and equity efforts in urban planning, I decided to pursue my Master’s degree in Sociology of Education at NYU–both so I could fulfill a lifelong dream of living in New York City and to further my research pursuits.

What did you find appealing about MPA during the interview process?
My education philosophy and research foci are centered in the holistic development of students, so it was beautiful to see so many people dedicated to developing the whole student and practicing education models that center student needs. I also found myself in a (virtual) space with people I felt incredibly comfortable with and could sense how fundamental community formation is at MPA.

What’s your big dream?
I have dreams of buying a farm, own lots of animals (we have five dogs now!), and growing a majority of the fruits and vegetables we consume.

What are you (and your family, if you so choose) passionate about?
My family is incredibly passionate about just that–family! We seize every opportunity to be together and spend quality time with one another. These days, that often looks like a group FaceTime where all you can see is all of our foreheads (I have no idea why we all FaceTime that way) and gatherings at our family home. The last big family outing we had was some months ago at Disneyland for my nephew’s first birthday!

What’s a fun fact about you that our community would love to know?
I am originally from California! The rest of my family currently lives in Southern California and my fiancée is originally from the Bay (Northern California), but she and her family moved to Minneapolis some time ago…which is what initially brought me here!

What position will you be holding at MPA?
K-5 Spanish Sub

From what school/organization are you coming?
Wayzata Public Schools

Tell us a little bit about your education and past experience.
My favorite job was being a 2 week program facilitator for El lago del bosque – Concordia Language Villages. I got my masters in World Language Intruction through Concordia College. I’ve taught at Armstrong High School, Totino-Grace high school, The Churchill School and Center (For Students With Language Based Learning Disabilities) and Wayzata public schools. Fun fact, I’m also licensed to teach Biology/Natural Sciences 5-12.

What did you find appealing about MPA during the interview process?
I met one teacher who said they went to school there and they wanted to teach there – that’s the kind of story that proves the school has major impact on people. Honestly….I saw the tree in the library and the mini door and knew it was the place for me. Also, the Spanish classroom had non-binary pronouns up on the wall as options, which made me feel included. (I’m leaving a district that was less inclusive). Also, all 3 directors are very genuine and easy to connect with.

What’s your big dream?
My big dream is to grow old and still be close with my two nieces.

What are you (and your family, if you so choose) passionate about?
I bike each day after work and read each night. My girlfriend and I enjoy knitting. I own a lot of plants and even name them….I’ve had a pathos named Viney for 14 years. My family revolves around local social justice/activist/art causes…mainly housing/renter rights and environmental stuff.

What’s a fun fact about you that our community would love to know?
I grew up surrounded by Croatian elders. I only have one great aunt left and we are very close.
