Heather Donaldson

I'm a New Yorker at heart but was born overseas in Aberdeen, Scotland. I graduated with my Bachelor's from SUNY Fredonia and attained my reading Masters from SUNY Brockport. I use it to help digest key components of word problems that students see in a math context. I enjoy supporting teachers with cooperative structures and management to heighten engagement and increase academic gains in their classes. I love to travel, lay out by the pool, cook, go to church and spend time with friends and family.

I was an Army medic from 1989 - 1992. While in the Army, I served in Desert Storm. After serving our country, I went to school to become a math teacher. I have taught middle school, high school, community college and at a few universities. I believe in having a great work ethic. I like helping hard working, struggling math students pass class. So, if you are hardworking and want to pass your math class, come see me!

I'm incredibly blessed to be able to teach in the town I grew up in! I went to Key, Gunston, and Wakefield. I graduated from JMU with a bachelors in Math. I'm excited to make math your favorite subject!
