About Me

Resume / Curriculum Vitae (CV):  Click HERE to view my current resume.

High School:  I grew up just South of Lincoln and attended Norris Public Schools.

Undergraduate Work: I graduated from Doane College in Crete, Ne with a Bachelor of Science degree in Mathematics in 1995.

Graduate Work :  I then graduated from Doane with a M.Ed. in Curriculum & Instruction in 1999 followed by a Ph.D. in Mathematics Education from the University of Nebraska-Lincoln in 2010. Click to access my dissertation: A Case Study of the Mathematical Learning of Two Teachers Acquiring Mathematical Knowledge for Teaching.

Teaching:  I began teaching mathematics at Mickle Middle School in Lincoln in the fall of 1995. During my seven years there, I taught 7th and 8th grade math as well as Algebra. I also coached the MathCounts team. I moved over to Lincoln Southwest High School when it opened in 2002. During my thirteen years there, I taught a mix of Algebra Block, Algebra, Geometry, Advanced Algebra, Pre-Calculus, and Problem Solving. I was also the department char during my final six years there. I enjoyed leading a fabulous group of math teachers! I made the move over to Waverly High School in August, 2015! I continue to be excited to serve the students of the community I live in! During just my 2nd year at WHS, I was able to teach 2 new mathematics courses at WHS: College Statistics (with the option to dual-enroll at SCC) and Differentiated Geometry! I am fortunate to teach those again this year. I’m also the co-sponsor for student council and the WHS quiz bowl coach. We had close to 150 students interested in quiz bowl last year. I do enjoy spending time with WHS students.


Family: Katie and I were married in 2000. She is a BSN/RN and the branch manager for Angels Care Home Health in Lincoln. We enjoy traveling, spending time with family, and living on an acreage just South of the high school. We have two daughters (along with two black labs, a shih-poo, and toy poodle).

Lauren is now a freshman at UNL…a business major…living in the Suites as part of the Honors program…(loving college!!!). Brianna is a 10th grader at Waverly Middle School. She plays the oboe & piano as well as the sax (for marching band). She is also part of student council, quiz bowl, golf, and tennis.

Professional Development & Other Activities:  I have attended numerous state and national level math conferences in addition to several national Texas-Instruments conferences. I have led many staff development workshops for Lincoln Public Schools as well as presented at regional and state conferences on various topics, including technology (e.g., graphing calculators and iPads), instructional strategies, and the importance of integrating the NCTM Process Standards in the classroom. I was a writing team member for the LPS Mathematics Demonstration Graduation Exams, facilitator for LPS math staff development collaborative groups, and a member of the Advanced Algebra revision committee. I have also taught summer courses to middle schools at the Nebraska Scholars Academy and Bright Lights.

For much of the past decade, I have taught graduate courses for the Teaching, Learning and Teacher Education Department as well as the Mathematics Department UNL.

For the past seven years I have been teaching statistics and college algebra for Nebraska Wesleyan University. This fall I am teaching a section of stats as well as a section of College Algebra.

I also teach statistics for Bryan College of Health Sciences. This fall I have two sections (including two WHS graduates!!!)

From 2004-2009, I worked with UNL on a project to help “create a national model for developing middle-school mathematics teacher-leaders who will mentor peers and offer challenging courses to their students.” For more information about Math in the Middle, visit the website at http://scimath.unl.edu/MIM/

Grants: I was awarded an Energy grant from the Nebraska Math & Science Initiative in 1997. Students learned about sound and had the opportunity to tune pop bottles using graphing calculator technology. I was named a GTE GIFT GRANT fellow in 2000. Students learned about wind turbines and had the opportunity to design their own blade systems for a small turbine. I was also awarded a “clicker” grant from Turning Technology in 2010.

Presidential Awards for Excellence in Math and Science Teaching (PAEMST): I was one of two Nebraska state finalists for the PAEMST award in 2007, 2009, and 2011. I was named the Nebraska Awardee for 2011 and spend a week in Washington D.C. during June, 2012. This was quite an honor.
