Hi! I am Crystal Bubick, honored to be one of the Instructional Coaches here at RMCA. Not only am I blessed with a beautiful family, a wonderful husband, and daughters who inspire me every day, but I also have the privilege of working with some amazing students and dedicated educators. I am so grateful for our RMCA community. Go Knights! I have three degrees from the University of Denver and have been in education for almost two decades. Colorado is my home. The mountains are my backyard. When I am not at RMCA, you will find me exploring the Rocky Mountains, taking in the symphony of the beautiful Colorado skies, adventuring with my tribe, and chasing sunshine and water.

In my free time, I enjoy crafting, reading, and of course, coffee!!

My name is Grace Rempe and this is my second year at RMCA. I love my job because I have seen how confidence-boosting and impactful education is in shaping how people view themselves and the world around them. It is my desire to teach my students not only what they need to know, but also to help them understand what they are capable of. I want students to know they are inherently valuable and loved. In my free time you might find me out for a run, reading somewhere outside, playing cards at a coffee shop, or training for a bike-packing trip a friend and I are planning (any tips welcome). I am originally from Iowa where my parents and younger brothers still call home.

Hi, my name is Lisa Robbins. I’m starting my 5th year working at RMCA. I’ve lived in Colorado for 25 years. I was raised in Iowa, but later moved to Colorado to attend Fort Lewis College in Durango. I’ve been married to my amazing husband, Justin, for 19 years. Our two sons attend RMCA. Our oldest son is starting middle school and our youngest son is entering 5th grade. In my free time I enjoy having lunch with friends, reading, and watching my sons play baseball.

I am so excited to be teaching 4th grade this year! I earned my B.A. in Social Science and Education and have experience teaching a variety of elementary grades. I love building a classroom community where every student feels encouraged, supported, and inspired to learn. One of my favorite things about teaching 4th grade is watching students grow in their independence and confidence. Outside of school, I enjoy music, gardening, traveling, and spending time with my family.

Hello! My name is Madison Shrum, and this is my second year at RMCA. I received my Bachelor’s Degree in Clinical Psychology and am currently in my final semester of graduate school where I am earning my Master’s Degree in School Counseling, both from Adams State University.

I’m originally from Southern California, and I moved to Colorado Springs a little over a year ago with my husband, Jarrett, and have loved every minute of it. I’m looking forward to a great school year and the opportunity to support your students!

Hi, I’m Kristin Siekmeier, a Colorado native, and this is my 13th year teaching and my eighth year at RMCA. I absolutely love teaching and working with kids. I’m so excited to be teaching fourth grade this year and can’t wait for all the learning and growth ahead. Outside the classroom, I love being in the mountains, spending time with friends and family, and cozying up on the couch with a good book. I’m a lifelong learner myself, and I hope to inspire my students to develop that same love for learning every day in our classroom.
