Mike and Terri Leonard

Mike and Terri's Davis Tutoring Center is located near downtown Davis. The tutors, Mike Leonard, PhD, and Terri Leonard, MD, have 40 years of combined experience tutoring full time with hundreds of students from Davis and surrounding communities.  2018 is the fourth consecutive year that the readers of the Davis Enterprise have voted Mike and Terri's the best tutoring service in Yolo County. They tutor math, science, English, and Spanish for grades 7 through college. They also offer assistance with SAT preparation and college counseling for all their students. They were formerly known as "Academic Improvement Center."

Both Mike and Terri tutor math, science, Spanish, and English, which means that students do not have a "subject-specific" tutor. Rather, a student can get help with his AP physics homework, his English essay, his AP Spanish homework, and prepare for his calculus test all in the same hour.

Additionally, because they have a tutoring center (rather than meeting students in their homes), their students are encouraged to come to their office at any time to use their resources. Many of their students spend several hours a day at their center.

Free tutoring hours are available to their students. When a student cancels his regularly scheduled tutoring session, any of their other students may "drop-in" during that time at no additional charge. This is a very popular feature of their tutoring center.

Because they have tutored in Davis since 1997, they are very familiar with the classes and teachers in the Davis school district.

Their students vary widely in academic ability and motivation, and their tutoring is individualized to meet the specific needs of each student.

They require no enrollment fees or long-term contracts.

About the Tutors

Mike Leonard, Ph.D.

Mike earned a bachelor's degree in geophysics from the Department of Earth and Planetary Sciences at the University of California at Berkeley, and was awarded the departmental citation for the highest academic achievement among his graduating class. He then stayed on at Berkeley to earn a doctorate in geophysics, a State of California Teaching Credential in math and science, and a wife, Terri. Prior to opening Academic Improvement Center, Mike divided his time as a research scientist, consultant, and educator and has been a classroom teacher up to the college level.

Terri Leonard, M.D.

Terri graduated phi beta kappa and summa cum laude from U.C. Berkeley with a degree in psychology, a State of California Teaching Credential in math and science, and a husband, Mike. She then dropped out of U.C. Berkeley's Bolt Law School to attend medical school at U.C. Davis, graduating in the top tier of her class. Upon graduation she was persuaded by her husband to abandon medicine and join him in a blossoming business he had recently started. Terri has also worked as a classroom teacher in math and science at the middle school and high school levels.
