Hi! My name is Sierra and I have the privilege of being the Center Director of Mathnasium of Cherry Hills I was first introduced to Mathnasium when I was in high school in 2012. After working as an instructor for a little while, I went off to college at Colorado School of Mines! I graduated with a degree in Mechanical Engineering and a minor in Biomechanics. But I quickly learned that, while I liked learning engineering, I didn't actually like doing engineering.
So I went back to what I had enjoyed and returned to Mathnasium. I took an opportunity to be an Assistant Director before quickly moving into the role of Center Director! It's an amazing time, being able to see a student who has struggled for a long time, finally understand something. I focus on creating a space where it's okay to not know everything and it's okay to make mistakes, because that is where the best learning happens!
Outside of work, I adore animals—my dogs, Kili and Winter, even come to work with me! I excel at picking up random arts and crafts projects for a few weeks before moving on to something else. I enjoy reading, particularly fantasy, and writing. I also have a lot of fun with a group of instructors playing Dungeons & Dragons as well as Daggerheart! I enjoy traveling and have been to every continent except Antarctica (Africa is my favorite).
I hope you stop in sometime! I'd love to meet you and your family!
I moved to Denver from L.A. in 2021 with the love of my life, Bridgette. Since graduating from Harvey Mudd College with a Mathematics degree, I’ve held many jobs—from software developer to stage manager—but nothing has been as immediately rewarding as teaching at Mathnasium. Seeing a student’s “aha” moment never gets old!
Outside of work, I enjoy yoga, cooking, and video games (a lot of video games). I’m still working on embracing Colorado’s outdoor lifestyle, but for now, I remain an indoor cat. I look forward to getting to know all the students and families at Mathnasium!
Youngkun's journey in education began with his pursuit of a bachelor’s degree in Pure Mathematics at Revelle College, University of California San Diego (UCSD). However, his passion soon shifted towards math education, prompting him to change his major to focus on secondary education. Since 2013, Youngkun has been actively involved in tutoring and various educational initiatives, demonstrating his commitment to education both within and beyond academia.
In January 2015, Youngkun became an instructor at Mathnasium, driven by a desire to make a direct impact on students' mathematical experiences. His dedication and leadership abilities quickly became evident, and by late 2017, he had transitioned to the role of Center Director. His continued success led to his promotion to Director of Operations in early 2023, where he now oversees multiple Mathnasium centers, including those in San Diego, Phoenix, Denver, Dallas, and Cincinnati.
Youngkun firmly believes that every student deserves to approach math with confidence. He is a staunch advocate of the Mathnasium method, which emphasizes a deep understanding of mathematical concepts and aims to eliminate the fear of math that often impedes student progress.
Committed to fostering the personal and professional growth of both instructors and students within his region, Youngkun strives to create an environment where learning math is a positive and empowering experience.

Hello all! My name is Daniel and I am a newer resident to Colorado. Originally from Texas, I earned my Bachelor's in Interdisciplinary Science with a minor in Physics from Texas State University, along with my teaching certification. I'm both a scientist and a teacher by profession—and a nerdy musician in my free time! I play guitar, trumpet, and bass.
Math didn’t click for me until I took physics and realized it’s a powerful tool for understanding the world. Now, I hope to help students see the hidden beauty of math. Also, I love RPGs—because watching numbers get bigger is always fun!
Hi, I’m Micah, I'm a student at Thomas Jefferson. I am personally enthusiastic about math, and hope my work can help to spread its beautiful nuance, through proof and intuition. It is my mission to help my students achieve a complex understanding and love of mathematics. Currently, I am learning differential equations, and I am excited to move forward in my mathematical education.
When I am not working, you will find me both road and mountain biking, building and coding robots for my school’s SpartaRobotic 3648 team, cooking various dishes, and you guessed it, doing math for fun! If you’re lucky you may even catch me biking or unicycling to work as I often do.
I hope to meet you soon!
Hi! I’m Harry, and I’m a student at Colorado Early Colleges. I love math and it’s my favorite subject. I’m very enthusiastic to teach it and help students out with something I enjoy so much! I’m currently in Calculus 3 and working to get better every day!
Outside of work and school, you can find me hiking, biking, driving, and in general just having a fun time with friends! I love coding and engineering and I’m working on becoming an engineer major. I love teaching and working with kids, it’s such a great feeling to help students understand something!
Hey, I’m Cooper, and I am a student at Cherry Creek High School. I have always felt myself drawn to the field of mathematics and its amazing applications. I am currently taking Differential Equations, Introduction to Real Analysis, and researching Markov chains and stochastic processes. The further along I get in my understanding of math, the more I come to appreciate its elegance, sophistication, and increasingly important place in our daily lives.
Outside of work and the classroom, I spend my time programming, volunteering, playing basketball, and doing things with my friends and family. I especially enjoy watching movies (David Fincher films are some of my favorites), and often lose much of my day to them.
I have always loved tutoring, and I find it to be some of the most gratifying work I do. I can’t wait to extend my love for math, and aid in the development of amazing math skills, to whomever I can!
