Diane Leisher is the Director of Foster Academy. Ms. Leisher's career has spanned both the corporate and academic worlds.  After teaching mathematics in public schools and earning her Master of Science degree in Mathematics from Texas A&M University, she entered the corporate world. Ms. Leisher worked in a variety of industries with an emphasis on the computer side. She presented technical seminars, developed and verified mathematical calculations for computer systems, tested software, trained users, documented software and processes, performed quality assurance, and wrote and published technical research papers and newsletters. Ms. Leisher has always used math and wants students to realize its diverse applications.

In January 2002, she "retired" to Alabama A&M University (AAMU) where she became an Assistant Professor in the Department of Mathematics. In addition to her teaching responsibilities, she served as an academic advisor for Mathematics majors and on numerous Department and University committees, including the Quality Enhancement Plan (QEP) - a required document for the University's accreditation process. After her retirement from AAMU in July 2015, she continued teaching as an Adjunct Instructor at Oakwood University and AAMU. She loves watching students' "light bulbs" come on with math!

Ms. Leisher is a Certified Laughter Leader, firmly believing in the health and mental benefits of laughter - conducting laughter programs throughout the Huntsville area. In her "down" time she enjoys being with her daughter, Mindi, and her family - especially Harbor, her young granddaughter, reading and applying self-help concepts, and learning new skills.
