Personal information

I am an Alumna (both undergraduate and graduate) of Appalachian State University. My Master's Degree from ASU is Mathematics with a College Teaching Concentration, and my Bachelor's degree from ASU is Applied Mathematics with a minor in Computer Science. During my time at ASU as an undergraduate, I also had fun serving as the ASU Math Club President (see picture). Picture of me as math club president, at club expo.

I am mom to a 10 year old daughter who adds a lot of fun to life (see picture at top of the page). I love animals, with 2 adopted dogs, 1 adopted cat, and 2 bunnies at home. My hobbies include dancing Argentine Tango, Rock Climbing (primarily top roping), Mtn Biking (some street also), and pretty much anything outdoors: backpacking, camping, hiking, white-water rafting, etc.

I started helping others learn math in a professional setting back while I was still in high school, working at a local children's home in Avery County as a math and science tutor. After that, I worked with elementary/middle schools around the Boone, NC area, helping children with math through the Watauga Youth Network after-school program. I began teaching college level courses in 2004, and college instruction has become my specialty. I have worked with an array of colleges throughout the last 13 years, primarily throughout the state of North Carolina: Caldwell CC&TI, ASU, Blue Ridge CC, Spartanburg CC (in South Carolina), Cleveland CC, Central Piedmont CC, Stanly CC, and Rowan-Cabarrus CC. While I have been involved with a lot of colleges, the majority of the last decade was shared between Cleveland CC (3 years) and Rowan-Cabarrus CC (6 years). Another fun teaching experience came from back when I was in the Master’s Degree Program here at ASU, when I had the amazing experience of teaching for a semester in a Master’s Program in Puebla Mexico.

The joy I find in teaching math is helping others to appreciate and understand or connect with any aspect of math. I have committed my life to teaching math in order to help others have 'ahh-ha' moments and to realize how cool (and useful) mathematics really can be for all of us. I am excited to now be back at Appalachian State University. I speak from experience when I say, “Studying at ASU is an unmatchable educational experience".
