Cynthia Prentice-Craver has been teaching human anatomy and physiology for over twenty-eight years at Chemeketa Community College. Cynthia’s teaching experience both in grades 6–۱۲ and in college, her passion for curriculum development, and her appetite for learning fuel her desire to write.

Her M.S. in Curriculum and Instruction, B.S. in Exercise Science, and extended graduate course-work in biological sciences have been instrumental in achieving effective results in the online and on campus courses she teaches.
