Talena has enthusiastically returned to San Diego thanks to her Navy husband most recently from the US island territory of Guam. She is originally from Houston, TX and followed in her love of numbers and her parents’ career path by majoring in finance at the University of Texas at Austin (Hook ‘em, Horns!), eventually earning her Master of Business Administration before deciding that she liked teaching about mathematics more to students than to adults. She became a teacher in 2006 and earned her master’s degree in education from UT Arlington in 2014. Talena has taught for several years internationally as well as here in California and is extremely excited to bring her love of mathematics to more students! When she’s not in the classroom, you’ll find her either being sat on by one of her three cats or out on one of the many hiking trails in East County. Please feel free to ask her for water or snacks if you need it, she always has extra!
