Michael Sullivan, Emeritus Professor of Mathematics at Chicago State University, received a Ph.D. in mathematics from the Illinois Institute of Technology. Mike taught at Chicago State for 35 years before retiring recently. He is a native of Chicago's South Side and divides his time between Oak Lawn, Illinois, and Naples, Florida.

Mike is a member of the American Mathematical Society and the Mathematical Association of America. He is a past president of the Text and Academic Authors Association and is currently Treasurer of its Foundation. He is a member of the TAA Council of Fellows, and was awarded the TAA Mike Keedy award in 1997 and the Lifetime Achievement Award in 2007. In addition, he represents TAA on the Authors Coalition of America.

Mike has been writing textbooks for more than 35 years and currently has 15 books in print, 12 with Pearson Education. When not writing, he enjoys tennis, golf, gardening, and travel.

Mike has four children: Kathleen teaches college mathematics; Michael III teaches college mathematics and is his co-author on two precalculus series; Dan works in publishing; and Colleen teaches middle school and secondary school mathematics. Twelve grandchildren round out the family.

Mike Sullivan, III s a full-time professor at Joliet Jr. College with training in mathematics, statistics, and economics. Built from experience in the classroom using feedback from his students Mike has numerous Pearson textbooks in publication including a Developmental Math series and two Precalculus series and a statistics series. When not in the classroom or writing, you'll find Mike trying to sneak in a round of golf if the schedules of his three children: Michael, Kevin, and Marissa allow it. Which might be a little easier now that Michael and Kevin are both in college.
