Welcome to Cimarron Middle School in Parker, Colorado. It is an honor to be the principal in such an incredible community. I graduated from the University of Northern Colorado, with a Bachelor's degree in Statistics. I pursued my passion and started my career in education at Valley High School and Liberty Middle School before moving to Douglas County School District. With these experiences, I am honored to be a part of Cimarron Middle School’s staff. I have been fortunate to be a part of the Legend feeder since opening as a math teacher, assistant principal, and principal. My wife is a teacher in DCSD and we are so excited for our two kids to begin their education in the Legend feeder. I have always had a passion for being around students and supporting others in their pursuit to achieve their goals. I believe in Cimarron’s mission in building relationships that help foster a positive learning environment. I look forward to partnering with you to build a great foundational middle school experience.

I am so excited to be a part of the Cimarron family again this year!  I graduated from Metropolitan State University with a Bachelors in Biology and then earned my Masters in Education Leadership from Regis University.  I have spent 14 amazing years in education so far.  During that time I taught middle school science for six years and then served as a middle school assistant principal for the past seven years.   My heart and passion lies with supporting middle school students, staff, and families.  I believe that by providing safe learning environments coupled with top notch instruction, every child can succeed academically, socially, and emotionally in order to become a life-long learner with a focus on individual growth.  I am looking forward to another amazing year supporting Cimarron staff, students, and families

I am beyond excited to be joining the Cimarron family this year!  I received my bachelors degree from Colorado State University and my masters degree from the University of Colorado and am entering my 18th year in education.  During that time I have had several roles as a teacher, coach, and administrator.  I live in Franktown with my husband, two daughters, and three crazy dogs.  I am passionate about education, supporting this community, and empowering others.  I am looking forward to a wonderful year.  Go Colts!

I am so so excited to be coming back to Cimarron for the fourth year!  Being born and raised in Nepal, I grew up looking at the beautiful mountains. My educational journey brought me to Minnesota, where I completed my Bachelor's and Master's degree in speech-language pathology.  Since I missed the mountains so much, I moved to Colorado with my wonderful husband in 2015.  I worked at three different schools in low socio-economic neighborhoods in Denver for a year before moving to Douglas County School District.  I have been fortunate to work with students in preschool, elementary, middle, and high school throughout my career.  My lifelong hunger for learning made me want to pursue a Master's Degree in Educational Leadership, which brought me to Cimarron!  Educating the whole child is a philosophy I believe in which requires all stakeholders' support.  I value relationships and teamwork and look forward to getting to know the students, staff, families, and the community at Cimarron.  I am so glad to be a part of an amazing school!
