Our Team at Mathnasium of Bentonville

Cheri Summerfield

Cheri earned her BA in Mathematics from the University of Arkansas after retiring from dairy farming. With over 50 years of tutoring experience, she brings patience, understanding, and a lifelong love of math to every student she teaches. 

Her dedication and encouragement help students see math as something to explore and enjoy, not fear. 

Aaron Smiley

Aaron holds a Bachelor of Science in Mathematics from the University of Arkansas and currently teaches at Haas Hall Academy in Bentonville. He loves showing students how useful and empowering math can be in everyday life. 

When he’s not teaching, Aaron enjoys playing woodwind instruments, learning French, and spending time with his dog, Seven. 

Daryl Breithaupt

Daryl grew up in Rogers, graduating from Westside, Oakdale, and Rogers High School. He studied at Hendrix earning a double major in Chemistry and Religious Studies. Daryl then completed nearly 4 years of service in the US Peace Corps living in a rural village of ~250 people in Niger, West Africa. Upon his return he completed a B.A. and M.A. at St. John's College in Santa Fe, NM. Along the way Daryl developed a love and appreciation for mathematical thought from the ancients to the moderns and would very much like to share that affinity with the learning community at Mathnasium.

Favorite Number: Graham's Number! It will literally explode your mind!

Favorite Math Joke: Math is no joking matter! Seriously, tell whoever said that I want to know!

I love Mathnasium because…. Learning with others is always worthwhile and Mathnasium is a great place to experience that!

Brian Stephenson

I am a native of Northwest Arkansas graduating from Bentonville High School in 2009. I graduated from the University of Arkansas in 2012 with my bachelors of mathematics and a minor in education. After teaching a few years in the public school system, I saw that students are struggling with math more than I ever expected. I saw that most students need help and guidance on the art of learning. Mathnasium helps expand my knowledge by showing me a variety of teaching methods and techniques, so that I can help a more diverse group of learners.

John (Johnie) Brandt

Johnie grew up in San Diego, CA. After receiving his Bachelor of Science in Molecular Biology, he attained an MBA. Together they helped him with several jobs/careers. Oddly enough, he often used math to figure out problems within those careers. Outside of his business life, Johnie spent almost 20 years coaching gymnastics. No specific math there, but he certainly enjoyed helping his students learn to set goals and work to achieve them. Why Mathnasium you might ask? Well, Math, especially Calculus, was always a favorite subject since it just made sense--no subjective answers, always just right or wrong; plus, it was based on logic and reason. Now that he is retired, he plans to help students understand math better, because it is a subject that will always help you no matter what you choose to do in life.
