Owner and Teacher

Hello, my name is Kristin Hammer. I created Nature Together because I love teaching young children and I have a passion for the great outdoors. I have seen first hand how engaged children become with the natural world and how excited they are to learn about wildlife.


I moved to Mukilteo 9 years ago from Illinois with my husband and, at the time, 3 year old son. We were in awe of Washington’s beauty and started exploring the parks in our community right away. We now have three kids and continue to take them outside to learn, play, relax and exercise.


I have a bachelor of science degree in ecology from Winona State University in Minnesota. After I received my degree I traveled around the country doing work in the ornithology (study of birds) field. During my few years of bird work I discovered that I had a passion for teaching. I then decided to go back to school to earn a masters of science degree in curriculum and instruction with an emphasis in environmental education from Northern Illinois University. I have taught in museums, nature centers, parks and preschools. I also completed Erin Kenny’s teacher training and became a Cedarsong-Certified Forest Kindergarten teacher.


In my spare time, I like to spend time with my family (husband, three kids, and 2 dogs), walk in the gulch, visit the mountains, the beach, and work in my garden.




My name is Theresa Costanzo and I will be joining Kris on her adventure with Nature Together.


My husband and I moved to Washington in 1997 and have raised 2 boys here. Having grown up in Pennsylvania, Texas and North Carolina I have been able to experience diverse natural surroundings but I admit the Pacific Northwest is my favorite. Our access to such variety: beaches, forests and mountains, is unmatched.


I have assisted in a traditional Preschool environment for the past 13 years and plan to apply all I’ve learned to the Nature Together model. I have always taken an active role in my boys’ education, volunteering in their classrooms, and leading the Art Docent program at their school. I am a Certified Yoga Teacher having studied Viniyoga at Whole Life Yoga in 2013 and have been sharing movement and mindfulness with kids and adults since then.


I make time for a workout every day. I am passionate about fitness and healthy food and how they contribute to our emotional and mental wellbeing.




Hello, my name is Alyssa Burrows and I am delighted to be joining the Nature Together team. 


I grew up in Sonoma County, California, and moved to Mukilteo in 2021. I have thoroughly enjoyed experiencing all of the biodiversity western Washington has to offer, and tide-pooling has become one of my favorite hobbies.


I graduated from the Santa Rosa Junior College with a degree in Natural Sciences and I am currently attending Cascadia College’s Bachelors of Applied Science - Sustainable Practices program. I discovered my passion for education while teaching horseback riding, and continued connecting children with nature while working with San Luis Obispo Botanical Garden. Outdoor experiences play such an important role in enriching children’s education and appreciation of their community’s environment - I’m so excited to be a part of that with Nature Together! 




Hi my name is Darla Bauer and I am thrilled to work with the elementary class.


I grew up exploring the pacific northwest and a formative experience the summer my dad was in the Forest Service cemented my love of the outdoors.


I spent 15 years building a career based on leadership training for adults with a bachelors degree in Liberal Arts and a masters in International Business. Having (4) kids of my own has shifted my focus to early childhood education.


In our family we learn about the world around us through the rhythms of each season. My kids have participated in the 1000 hours Outside challenge annually since 2019. We also love the Exploring Nature with Children guide.


Nature walks and bike rides have been a saving grace during the last few years and have led to a deep appreciation for the community of Mukilteo. 


Thank you for this opportunity to explore alongside each student. I know we will learn and grow together.

My name is Bryan Carli and I’m excited to be a part of the Nature Together teaching staff.


I was born and raised in the foothills of the Sierra Nevada Mountains in Northern California. Some of my most fond childhood memories were made hiking, camping, visiting river swimming holes and playing on the lake. This is where I developed my love for nature.


I completed a bachelors in Health Science, at Walla Walla University in 2004. This led me into public health education and I eventually completed a science teaching credential and a Masters in Education at the University of Redlands. I have over eight years of teaching experience with elementary and middle school-aged kids. 


My wife and I moved to the Seattle area in 2013. We love the PNW and have enjoyed raising our three children here. I have been a stay-at-home dad over the past nine years. I always enjoy exploring the great outdoors with our children, and I am excited that I get to continue exploring with the preschoolers at Nature Together! 



Substitute Teacher

Hi, my name is Susan Mays and I am excited to be joining the Nature Together program as a substitute teacher.


I was born and raised on Whidbey Island and have lived in the area most of my life. I now have the privilege of raising my own children (Indie and Lincoln) with my husband Adrian here in Mukilteo and I couldn’t be more grateful. I love the Pacific Northwest and all it has to offer – especially the forests and beaches where you can find us spending part of almost every day.


I have a degree in sociology from Seattle Pacific University and spent years working outside the home, but now enjoy getting to spend most of my time with our littles. I also love spending time doing volunteer work for a few local non-profits, running and being active, and exploring new places with my family. I’m looking forward to getting to know you and your child!
