Middle School Faculty


Crystal Davidson

Science - 6th

Mrs. Davidson has lived all over the western United States. Born in Nebraska, her family moved to northern Utah, western Idaho, and eastern Oregon. After high school, Mrs. Davidson returned to Idaho to attend Boise State University where she majored in biology with an emphasis in microbiology. During her senior year she worked as an intern for the Veteran’s Affairs Medical Center in Boise testing strains of Streptococcus pneumonia for specific antibiotic resistance mechanisms. After earning her Bachelor’s degree, Mrs. Davidson worked in the field of microbiology, identifying microorganisms and testing for antibiotic resistance, for the next 12 years. The monotony of testing the same organisms every day finally motivated her to search out a more stimulating career, and so teaching became career number two.

Upon completing her Master’s in Secondary Education, Mrs. Davidson went to work teaching 6-8 science. She is passionate about learning science by doing science and strives to find and create opportunities for her students to apply the scientific concepts, principles and skills they learn in the classroom to real-world problems and situations. She believes that learning how to think and solve problems like a scientist is important for everyone, even if you don’t plan on becoming a scientist. After four years teaching middle school Mrs. Davidson moved to the College of Western Idaho where she taught introductory microbiology and anatomy and physiology. While she enjoyed teaching at the college level, there were a number of things she really missed about K-12 teaching. She is grateful and excited to be at North Star!

Mrs. Davidson has been married to a pretty terrific guy for almost 20 years. They have three children, Ainslee (16), Mackenzie (14), and Joseph (12) and their dog, Sam. As a family they enjoy watching movies, eating out, camping, hiking, and vacationing.

Casey Hawkins

Math - 6th

Mrs. Hawkins grew up in a rural town, Mariposa, CA, just outside Yosemite National Park. She has always been actively involved in sports and anything that has to do with the outdoors. Her love of children and passion for teaching has been with her since she was a young girl.

After graduating on the Dean’s List with a Bachelor’s degree from Sacramento State, and earning a teaching credential from Chapman University, Casey moved to Grandview, ID, in October of 1995. Midyear, after three months of subbing, she was offered a full time second grade position at Mountain Home AFB. She spent the summers of 1996 and 1997 teaching Spanish speaking migrant ed. preschoolers. In 1997, she moved to Eagle, ID and taught in the Meridian School District for the next eight years. She has also spent fourteen summers tutoring students in math. Every position she has filled with passion and excitement.

When her boys arrived into this awesome world, it was apparent that she needed to be at home more; however, as much as she loved being home, she also needed to keep her feet in the classroom. While getting her Master’s degree in Administration, she also shared a fifth grade teaching contract for three years with Mrs. Mariah Rodeghiero, one of North Star’s amazing fourth grade teachers. This was an incredible opportunity that she thought she would enjoy until retirement…until she stepped foot into her first charter school.

Upon viewing what charter schools could offer students, immediately she knew it was part of her next phase of life. She was impressed and excited about working with a group of teachers that were all grounded in the same beliefs. She has spent the past twelve years successfully teaching with some of her greatest friends at a charter school; her students’ enthusiasm towards learning and their ISAT scores prove that the method North Star has to offer is exceptional.

Casey has been married for seventeen years to her best friend, Dan Hawkins, Asst. Fire Chief at Mt. Home AFB. They have three adorable lil’ men (ages 16, 14 1/2 and 13), so life is incredibly busy driving kiddos to sporting events and enjoying quality family time. Together they enjoy biking, snow skiing, waterskiing, camping, hiking, hunting, fishing, swimming, jet-skiing, and spending time with family and friends.

Casey looks forward to her 23rd year as a teacher and can’t wait to meet and develop working relationships with her upcoming sixth grade students and their families.

Trevor Holladay

PE - 6th

Trevor Holladay grew up in the great outdoors of North West Montana. He likes to spend his down time hunting, fishing, hiking, or playing city league sports such as volleyball or basketball. He is originally from Kalispell, Montana where he went to a private school K-12th grade. Following his passion for being physically active, he moved to Bozeman, Montana and went to Montana State University and received his Bachelor of Science degree in Health Enhancement. Trevor wants to instill upon his students the same passion he has for being fit and healthy.

Last year, Trevor coached middle school girls basketball and middle school boys basketball. He truly enjoys seeing children active outside of school exercising and learning new skills. This will be Trevor’s third year at North Star and he is excited to continue teaching new students and continuing to grow the Health and Fitness curriculum.

Audrey Speicher

Social Studies - 6th

Miss Speicher grew up a barefoot wild child on a bison farm near the one-stoplight-town of Bourbon, Indiana. She loves trying new things, which has led her to a vibrant and active life. Growing up, she loved musical theater, all sports, and playing in the woods with her brothers. She studied photojournalism at Indiana University while also being a paraprofessional instructor of outdoor adventure courses such as white water rafting, coastal kayaking, and backpacking. During college, she also got to travel the world as a creative problem-solving camp facilitator for children living on US Air Force bases in Japan, South Korea, and across the United States.

These experiences in college convinced her that she wanted to be a teacher, so after graduation, she moved to Houston, Texas, to live with family while she pursued a teaching certificate. After teaching 4th and 5th grade English Language Arts and social studies for a year in traditional public schools, she decided to spend her two-month summer break learning Spanish in Costa Rica. While there, she met a rowdy bunch of adolescents from a Montessori school in Houston, Texas, of all places! They invited her to be their teacher, so she took a leap of faith and began to teach 7th, 8th, and 9th grade English Language Arts, literature seminar, humanities, physical education, and project-based science at the small, private school.

In the meantime, most of Miss Speicher’s family decided to move to the northwestern United States, so she decided to follow by becoming a University of Idaho graduate student at the McCall Outdoor Science School field campus. There, she got to hone her ability to make science and learning fun and acted as the UL Diversity Scholar studying inclusive education practices. This was also where she was introduced to North Star Charter for the first time! North Star and the state of Idaho made such an impression on her that she decided to become a teacher here for good!

Entering her 6th year of formal teaching, she can’t wait to approach 6th grade social studies from a holistic perspective that encourages critical thinking, cultural appreciation, creativity, and collaboration. When she’s not teaching, you may find her rock climbing, playing the ukulele, or trying a new recipe.

Tyrel Whitt

English Language Arts - 6th

The soft blanket of snow that had cascaded gently down the night before now crunched under the early morning footsteps of the Whitt family as they welcomed the newest addition, Tyrel Cole Whitt, to their family. Six siblings, a myriad of sports, and an adventurous outdoor lifestyle led to 18 years of valuable experience and precious memories as Ty grew up in North Pole, Alaska.

After graduating high school he traveled to Eugene, Oregon to attend a junior college that had offered him a basketball scholarship, and eventually a baseball scholarship as well. Albertson College, now College of Idaho, recruited Ty as a pitcher, and Ty received his first true taste of the beauty Idaho had to offer. He graduated from C of I with a degree in elementary education in 1999.

The next five years were an epic saga of life changing experience as Ty worked as a hotshot firefighter in 12 different states and traveled internationally to 3 different continents. He was fortunate enough to marry his gorgeously brilliant and talented wife Heather in 2004, the same year he began his teaching career. Ty now has two beautiful and precocious daughters, Zinnia and Poppy, who are 7 and 3 years old respectfully. An aspiring author, he happily spends his free time reading, writing, playing games, and making artistic glass mosaics for his and his wife's art business, r.a.d. Mosaics. With over a decade of time spent encouraging junior high students to understand, value, and wield the power of language with respect and careful thought, he is returning to North Star with an enthusiastic attitude and high expectations. Every day is a learning opportunity as we read, write, laugh, and reflect.

GRADES 7 & 8

Kelly Dillon

Math - 7th

Welcome to 7th grade math for the 2017-2018 school year. My name is Mrs. Dillon and this will be my 2nd year with the North Star family.

My husband and I moved here from Pocatello, Idaho where I taught 6th grade math. I love teaching because it is a constant challenge and I get to be creative on a daily basis. No day is ever the same which makes teaching all the more exciting. I take teaching seriously and work hard to give each student the opportunity to have a successful math year. This past year, Mrs. Ellis and I also began the the MathCounts program at the school which is a combination of a Math Club and a competitive team for any students in 6-8th grade. Any students who love math and want to be challenged and learn cool new things are welcome to join.

When I'm not teaching, I enjoy exploring the outdoors such as road biking, hiking, fishing, and camping. I also enjoy concerts and playing guitar and clarinet. I am excited to start the new year and get to know each of you.

Krystal Ellis

Math - 8th

Krystal Ellis grew up in Cottonwood, Idaho and Moses Lake, Washington. After graduating from Prairie High School in Cottonwood, she attended the University of Idaho and took courses in Mining Engineering. She worked as an intern at a silver mine in Kellogg, Idaho for two summers before deciding that her passion lied in education. She took one semester of education classes and then took some time off to work. She enlisted in the Air Force where she served two years as a Korean Linguist and earned her A.A. Degree in Korean from the Defense Language Institute in Monterey, California.

She absolutely loves teaching at North Star last year and treasures the relationships she has built with her new North Star family.

Jennifer Kemp

Social Studies - 7th & 8th

Jennifer Kemp was born in Vermont and spent her early childhood in North Carolina. At age six she moved with her family to Idaho. After coming to grips with the fact that she would never be a princess, she decided to turn her love of school into a life long career and began pursuing her goal of becoming a teacher (she was 9).

In 2008 she graduated Suma Cum Laude from Lewis-Clark State College in Lewiston, Idaho and now holds a Bachelors Degree in Secondary Education/Social Sciences with a minor in History. While in college she discovered that, in addition to having a great love of history, she had a passion for the martial arts.

Jennifer has also spent the last couple years working with Global Service Partnerships to make service learning and cultural expansion opportunities in the beautiful country of Belize available to North Star students and families.

Daniel Hock

English Language Arts - 8th

Daniel Hock hails from Bedford, England, but regrettably does not have the accent. Instead, he has lived most of his life in the Treasure Valley, save for a year attending the University of Puget Sound where he realized he wasn’t cool enough to hang out with those cats. He quickly came back to his home of Boise and graduated with a B.A. in Secondary English Education from Boise State University. He’s never been to a Broncos game (but will tell you stories of many a Steelheads game), still hasn’t visited the old state penitentiary, and will always get Twin Falls and Idaho Falls mixed up. But he’s rafted down the Snake River, rocked out during Treefort, and at one point knew the baristas at Java who knew his order. Idaho has grown on Daniel over the years, not without a good dose of teenage angst, but he’s glad to call it home.

Daniel is glad to be returning to North Star for his second year, and putting names to the faces of middle schoolers that roam the halls. He's lived in Eagle for two years and has three dogs: Aurora, a pit bull puppy; Emma, a chow/lab mix; and Coots, a poodle/yorkshire terrier mix. It's a true menagerie. His meager free time is spentfinding new literature to read, particularly modern and postmodern works; playing video, tabletop and card games (ask him about Magic: the Gathering!); and trying to finish that novel that every English major is trying to write.
