Meet the Administration

About Tennille Foerster

This is my second year leading this amazing school, but I have been a part of the Sierra community for 20 years!  I taught 6th grade at Sierra for 12 years, my own children are Sierra alumni, and I was the assistant principal here the previous 6 years.  I am a product of Jeffco Schools, Weber, Moore, Pomona (I can still sing the Weber and Pomona school songs), and then went to college at Miami University, where I was a pitcher on their softball team.  I taught for 15 years, was an assistant principal for 8 years, and also did some coaching at Ralston Valley early in my career (softball and lacrosse).  I am a huge sports fan, love reading, and being with my family and friends.  “Work hard, play hard” are words I live and lead by.  I feel so blessed to be a part of this Sierra community, and am eager to continue developing established and new relationships with all of our students, staff, and families. 

About Brandon Rowland

Greetings Sierra! My name is Brandon Rowland, and I am your Assistant Principal. This is my second year serving in this role here at Sierra, but 14th as a school administrator. I started my career in St. Louis as a Special Education and math teacher after graduating from the University of Iowa – Go Hawks! I’m very fortunate to have the opportunity to bring my daughter to work with me and I love seeing Opal learn and grow as a kindergartener at Sierra. My wife, Kara, is a graduate of Arvada West and CU Boulder and in our free time, we like to travel, garden, play cards with friends, host Midwest-styled potlucks, and go camping. Our youngest daughter, Emma, is looking forward to being a Sabertooth!
