Personal information

I am an alumna of Appalachian State University, with a master's degree from Appstate in mathematics with a college teaching concentration, and a bachelor's degree from Appstate in applied mathematics with a minor in computer science. During my time at Appalachian, I also had the pleasure of serving as the ASU Math Club President! (see picture) Picture of me as math club president, at club expo.

I am mom to an 11 year old daughter, who is my world and definitely adds joy to life (see picture at top of the page). I love animals - with 2 adopted dogs, 1 adopted cat, and 2 bunnies at home. Hobbies for me include dancing Argentine tango, rock climbing, mtn biking, and pretty much anything outdoors: backpacking, camping- you name it.

I have always been a teacher at heart - helping others learn math since grade school. I became a professional math and science tutor at a local children's home in Avery County while still in high school myself. After that, I worked with an after school program, going into elementary/middle schools around the Boone, NC area, helping children learn math through the Watauga Youth Network (WYN).

My specialty has been teaching college mathematics since 2004. I have worked with students at several colleges throughout the last 14 years.

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 blessed to finally be back (back since 2017) at Appalachian State University.

I speak from experience when I say, “Studying at Appalachian State University is a life-changing experience".
