Linda Durgin

First Grade Math, Science and Social Studies Teacher

I’m honored to be joining the C3 team, teaching first-grade math, science, and social studies. My family and I hail from a suburb of Boston, Massachusetts. My husband, Frank, and I, along with two of our sons live in Denver and our oldest son moved back to Boston this spring. I’ll definitely share my love of the ocean and my seashell collection with your children! I visit every summer to reunite with our family and friends while enjoying the New England coastline. After teaching kindergarten and 1st graders in Massachusetts, I taught gifted learners at DU’s Ricks Center when we moved to Colorado. Then I found a home at Cory Elementary for years teaching first graders. I’m excited to be a part of C3’s mission and vision, which aligns with my passion for building a trusting community of children, their families, and myself as we grow and learn together.


Robin McCarthy

First Grade Literacy Teacher

Welcome to first grade! My name is Robin McCarthy and I will be working with your children teaching literacy. This includes reading, writing and spelling. I began teaching Third grade at Tollgate Elementary in Aurora Public Schools but I have been teaching first grade at Tollgate for the last four years. Tollgate is a school for Expeditionary Learning and I am discovering many commonalities with C3.

I grew up in Colorado and enjoy spending time in the mountains both skiing and hiking. I am a resident of Park Hill and my children, Sean 25, and Riley, 23 both attended Denver Public Schools. I’m looking forward to getting to know your family and watching your child grow.




Mariel Galgas

Second Grade Math and Science Teacher

Hello! My name is Mariel Galgas and I will be teaching second grade math, science, and social studies at C3 for the upcoming school year. This year will be my sixth year teaching. I have taught both second grade and kindergarten.  I moved to Denver from New Jersey four years ago to teach, pursue my master’s degree, and to take in all of the wonderful things that Colorado has to offer. I have a B.A. in Psychology with an Elementary Education Certificate + Middle School Mathematics Endorsement and I also have an M.A. from the University of Colorado in Curriculum and Instruction with a focus in Elementary Reading and Writing. In my free time I enjoy hiking, skiing, playing volleyball, yoga, crafting, cooking, camping, and learning. I am excited for the new adventures that working at C3 will bring!


Margaret Wing

Second Grade Literacy Teacher

I received my Bachelor’s Degree in Elementary Education from the University of Northern Colorado. After teaching for a few years, I earned my Master’s Degree in Curriculum and Instruction with an Emphasis in Reading and Writing from the University of Colorado at Denver. I love teaching and working with kids. Teaching gives me the opportunity to learn something new every day and appreciate the energy it takes to master new skills. It is amazing to be a part of supporting students as they grow and gain confidence in their abilities and understanding of themselves.

In my free time, I enjoy spending time with my family and friends, reading, baking, gardening and doing projects at home. I love to take walks with, throw balls to or just hang out with my golden retriever, Annie.

Ashley Bromstrup

Third Grade Math and Science Teacher

I grew up in Fort Collins, Colorado. I earned a Bachelors’s Degree in Studio Arts from Seattle Pacific University and a Master’s of Educational Psychology from University of Colorado at Denver. I am thrilled to find a school home that combines my love of the arts and creativity with my love of teaching second graders. Before C3, I was a 2nd and 3rd Grade co-teacher at The Odyssey School and before that I was an intern at the Stanley British Primary program. Personally, I have some itchy travel feet and I love to explore Colorado in any way I can. I divide my free time between painting, hiking, biking, camping, and calligraphy.

Natalie Rigert

Third Grade Literacy Teacher

Hi, my name is Natalie Rigert and I am thrilled to be joining the C3 team as the third grade literacy teacher. I grew up in Bettendorf, Iowa. I am the oldest of three. I attended the University of Iowa- go Hawks! I majored in elementary education with specializations in reading and language arts. Over the past 7 years I have lived in 3 different states (Iowa, Illinois, and Virginia) and I had the pleasure of teaching grade levels K-3. My husband, Jake, and I finally found our way to Colorado this spring and we are here to stay! I love traveling, hiking, reading, and playing with our dog Callie. My goal is to provide a high quality, individualized education for every child. I am passionate about what I do and I love being a part of a student’s learning process. We are going to have a great year!


Mallie Buffum

Fourth Grade Math and Science Teacher

I am so thrilled to be joining the staff at C3 this year. I have always admired C3, and I can’t believe I’ve been given the opportunity to work here. A little bit about me: I grew up in a small coastal town in Connecticut and ended up going to a small liberal arts college in upstate New York called Skidmore College where I majored in Education and minored in American Studies. After I graduated, I came out to Denver to nanny for my cousin’s children and loved it so much I just never left. I started my educational career as a paraprofessional in a kindergarten classroom at Stephen Knight and then spent last year as a 4th grade teacher at Traylor Academy. 4th grade is definitely one of my favorite grades, so I am so fortunate to be able to teach it again. I love spending my free time on hikes in the Rockies, hanging out at my family’s house in Grand Lake, and exploring everything Denver has to offer. I can’t wait to meet everyone at C3 this fall.See you in August!



Austin Rand

Fourth Grade Literacy Teacher

Austin Rand will be joining us from Joe Shoemaker Elementary to teach 4th grade focusing on literacy alongside Mallie Buffum who will continue with math, science and social studies. Austin has been teaching in a multi-aged 4th and 5th grade classroom.

Born in the Greater Boston area, I have lived in Denver, Oakland, and Boston over the past ten years. I attended the University of Colorado – Boulder for my undergraduate degree and completed my Masters in Education at UC Berkeley in 2016. For the past year, I have been teaching 4th and 5th grade at Joe Shoemaker School here in Denver. When I am not teaching I can usually be found outside: running, riding my bike, camping, or skiing, somewhere in Colorado.  I look forward to joining the C3 community next year!

Fifth Grade Literacy Teacher


Lisa Iverson

Fifth Grade Math and Science Teacher

I have lived in Colorado for 12 years.  I grew up in Alaska, with mosquitoes, rabbits and mussels (the shellfish) as pets.  After a summer arts camp in middle school, I fell in love with Shakespeare, and went on to earn an M.A. degree in Theatre Arts. I have attended universities in Oregon, Washington and Colorado, most recently earning my teaching credentials at CU Boulder.  Through theatre, I discovered a new love: helping people learn.  I have taught students of all ages and from many backgrounds.  For the past 6 years, I have taught 3rd, 4th, and 5th grade students at Cory Elementary. During that time, I was also a member of the C3 design team, and helped shape the education plan.  I spend my free time with my husband, family and friends.  For fun, I enjoy cooking or getting outside to hike, travel and play.  I also enjoy visiting art galleries, seeing theatre and live music, and reading voraciously under the covers with a flashlight.



Susan Halstead

Music/Admin Assistant culture and community

Susan Halstead is joining C3 as our music and PE/Dance teacher. Ms. Halstead received her Bachelor of Music Education from Michigan State University where she studied vocal music with her voice professor and Grammy Award winner, Molly Fillmore. She was born and raised in the Chicago area and now loves living in colorful Colorado spending most of her time skiing, hiking and running. She is so excited to be a member of the C3 community and is looking forward to a wonderful school year!​

BJ Kittleson

Visual Arts

I am a Denver native and I grew up in the Park Hill neighborhood.  I am a graduate of the University of Colorado with a Masters in Elementary Education.  I have taught first and second grade for 15 years.  The last eight years I have been a first grade teacher at Polaris at Ebert Elementary.  Educating at the primary level is a passion.  I believe it is the most important part of our lives.  My time outside of school is spent with my family.  I have a daughter, Elise who is 5 and a son, Bennett who is 8.  We spent a great many of nights in a tent during the summer enjoying our beautiful state.  It is my favorite to share beautiful natural places with my wife and children.  Outside of teaching I enjoy painting and drawing the amazing memories from being outside.


 Susan Logan

Reading Interventionist and Literacy Coach

I moved to Colorado in 1990 to learn to ski.  After hearing my father tell his friends he paid for college only to see me tend bar I decided to get serious about using my degree and in 1992 I began teaching first grade in the Cherry Creek School district (making much less than when I tended bar!) I taught first, second, and third grade in Cherry Creek for ten years and learned beside brilliant students and colleagues.  During this time I  pursued my Masters Degree in Curriculum and Instruction at UCD and began working with a staff development organization called the Public Education and Business Coalition (PEBC).  In 2002 I transitioned from working with children to working with adults and became a National Literacy Consultant for the PEBC.  In this role, I worked with teachers across the country  to develop and implement the best instructional practices in literacy.  Although I loved the work, the travel became challenging for my family and I found the most rewarding part of my job was when I was in classrooms with children.  The opening of C3 has provided me with the opportunity to return to a teaching position and what I missed most, developing a community with young learners.  As I walk to school each morning I feel a balance between three parts of me: the mother, the teacher and the learner.  I look forward to a tremendous year of learning beside your children.


Robb Mike

PE/Senior Team Lead

Twelve years ago, I arrived in Colorado from Hawaii, with the intent of completing a graduate program at DU and quickly returning. While I’d be lying if I said the ocean doesn’t occasionally beckon me, I couldn’t be happier having established roots in this vibrant and amazing state. This upcoming year will mark my 10th year in education, having spent the majority of it teaching curricula that was focused on experience, self-direction, and authentic application within Jefferson County Schools. I have had the opportunity to work with a variety of grade levels, from primary to middle school, which provides me with the unique ability to know from where students have come and to where they need to get. When I’m not working alongside the students, I can often be found running trails in the mountains and climbing on rocks with my wife and dog. I’m thrilled to be coming on board at C3 and look forward to sharing my ongoing passion and excitement for learning.
