The people behind XtraMath
From left to right:
XtraMath started in the fall of 2007 when David Jeschke, a computer programmer, volunteered at a local elementary school and recognized the need for an individualized math practice program.
XtraMath spread rapidly to other classrooms by word of mouth and the program continues to evolve to meet the needs of the students, teachers, and parents.
Our resident Photoshop, AfterEffects, Audition, and quality assurance wizard is Irene Nelson.
Irene likes the wilderness, football, and math's many contributions to the world of art.
The teacher who appears in the English-language student activities is Christopher Robert, a National Board Certified Teacher in the Seattle School District.
In 2009 Chris was honored as a "Hero in the Classroom."
Heading up our internationalization effort is Seattle native Jennifer Truluck.
Former French and Italian translator and teacher, Jennifer spends her spare time studying new languages and blogging about linguistic tidbits that strike her fancy.
Sterling Nelson has a BS in Biology from UC Davis but enjoys computer programming more.
Sterling spends his spare time playing and coaching Ultimate Frisbee.
The exceptionally patient Erika Newell answers email questions from parents and teachers.
She has a BA in Mathematics from DePauw University and likes helping people use technology to its full potential. Her children love using XtraMath.
Our Spanish-language math teacher, "Maestra A." is Claudia Mesa.
Originally from Colombia, Claudia now lives with her husband in Portland, OR, where she is the CEO of the popular children's language school "Kids Like Languages."
When not teaching, Claudia enjoys traveling and getting to know new cultures around the world.
The teacher who appears in the English-language introductory videos is Denise Ohlson (not pictured).
Denise is a National Board Certified Teacher in the Peninsula School District. In addition to being a teacher Denise is also a voice artist.
