Professional Educator and Mid-Level Professional Laboratory Scientist Available to Tutor Various Subjects


I teach STEM subjects, Reading, and ELA according to current common core curriculum, but I relate the strategies needed per the individual. I firmly believe in teaching to the individual starting where the student is in order to reach success.


I am a successful mid-level career biochemist who has also been a private K-12 tutor (STEM, Reading, and ELA) for 5 years. My double minor in college was biology and mathematics; and I enjoy manipulating numbers and teaching the subjects.
