Mike Sullivan, III, has training in mathematics, statistics, and economics, and brings a varied teaching background that includes 15 years of instruction in both high school and college-level. He is currently a full-time professor of mathematics and statistics at Joliet Junior College. Mike has numerous textbooks in publication, in addition to his Introductory Statistics Series, which include series in both Developmental Mathematics and Precalculus (written with his father, Michael Sullivan). Mike has built this new statistics book in the classroom using feedback from his students. He is well aware of the challenges faced by students taking an introductory statistics course. Mike’s goal is for students to be more informed interpreters of data so that they will be better decision makers and have stronger critical-thinking skills. When not in the classroom or writing, Michael enjoys spending time with his three children, Michael, Kevin, and Marissa, and playing golf.

George Woodbury earned a bachelor’s degree in Mathematics from the University of California—Santa Barbara and a master’s degree in Mathematics from California State University—Northridge. He currently teaches at College of the Sequoias in Visalia, CA, just outside of Fresno. George has been honored as an instructor by both his students and his colleagues. Aside from teaching and writing, George served as the department chair of the math/engineering division from 1999 through 2004.
