 Valerie Robertson I graduated from State University of New York (S.U.N.Y) at Old Westbury with a Bachelor of Arts degree in Sociology. This was after I completed an Associate's degree in Liberal Arts from Suffolk Community College, N.Y. I moved to NWA and completed my Master's of Arts in Sociology. As you can see, I am a non-traditional student, as many of you are. I went to school with children to care for and a full time job. It took me years, but finally after many adventures and changes of heart, I managed to pull off a Master's degree! With hard work, you can do it too! The journey is worth it

I love teaching at NWACC and living here in northwest Arkansas. It is like a dream come true. As a child, I wanted to be a dancer, a doctor, a teacher, among some of the dreams of mine.
