Evan Lossing

Evan's professional experience with Mathnasium began in 2013 when his family opened their first math learning center. Evan spent many summers and holiday breaks working as an Instructor. After graduating his bachelors degree in Business Management at Texas Tech, he began working as the Director of Operations for our family enterprise and has now relocated back to our hometown in Dallas, Texas! Evan is excited to work with our students and continue their progress with math. He, himself, struggled with math when he was in elementary school and with supplemental support was able to not only close his gaps but got into an accelerated math curriculum by the time he entered high school. Evan is a stickler for customer service and meeting and exceeding your expectations. He welcomes your recommendations. He looks forward to meeting you and sharing his passion for education with our mathletes.

Steven Lossing

Steve is the proud co-owner of multiple Mathnasium Learning Centers in Southern California, Arizona and Texas. Steve retired in 2018 from Petco, where he served as the Chief Stores Officer. He also served as the Treasurer and a Board Member of the Petco Foundation, a leading supporter of animal welfare organizations nationally. He now works full-time with his wife, Karen, two children, Libby and Evan and their terrific Mathnasium teams. Steve believes Mathnasium not only builds students' math skills, but also helps build their self-confidence. The Mathnasium method of teaching students math, the unique and customized curriculum for each student and the passionate team of instructors ensures that every student succeeds, whether they are catching up, keeping up or getting ahead!
