Thank you for visiting my site!  I am a high school mathematics teacher at ROCORI High School in Cold Spring, Minnesota.  I enjoy fishing, hunting, sports, and anything outdoors. I am currently continuing my education through St. Mary's University of Minnesota in the M.Ed. - Teaching and Learning program.  I am very excited to be advancing my career in education, and to be able to teach 21st century skills to students in our district!

(9/30/2015)  A reminder to all parents of ROCORI students, fall Parent/Teacher conferences will be held on Monday, October 12th from 4-8pm in the high school gymnasium.  Please try to attend!

(9/8/2015)  For all students who will be gone on vacation, have an appointment, or any other reason from school...if you know you will be absent ahead of time, please e-mail me in advance of the day you will be gone so I can put together class materials for you.  Thank you for your help!   

(9/1/2015)  Welcome back to school!!!

Dear Students and Parents,

Please make sure you have a graphing calculator for your math classes!  At ROCORI, we recommend the Texas Instruments TI-83 Plus or TI-84 Plus.  Either of these calculators are widely used throughout all high schools and colleges across the country.  If you do purchase one, bring it in to my classroom before school and I can engrave your name or initials into it to help prevent theft.  We understand these calculators are expensive, but they are an investment in your child's education and you will certainly need one past high school if you plan on going to college.  If you have any questions, please ask!

Thank you!
