Elliott Guiso, Center Director

Elliott started as an instructor at Mathnasium of Laguna Niguel in January of 2017. He had an engineering background, but wanted to work in an environment where he could do something to have a more positive impact on people. He found that kind of role at Mathnasium. After working his way to Lead Instructor and then Assistant Center Director positions at the Laguna Niguel location, he started as the Center Director for Mathnasium of Dana Point in September of 2019.

Learning math has allowed him to use logic and critical thinking skills to solve problems that relate to real world situations. That said, one of his favorite benefits of working at Mathnasium has been conquering the skills gap between solving math problems and teaching others how to solve them.

He enjoys books and games of all kinds, and he loves Indian food.

Advice to Mathnasium students: Put effort into learning everything you are required to, and put a lot of effort into learning about everything you are interested in. The experience of doing this will be infinitely more valuable to you in the future than your grades alone. Learning doesn't stop when you graduate - that is when it begins for real.

Fun fact: He is an all-around media “buff,” but especially when it comes to animation and rock music.

Favorite number: He likes prime numbers because they can either make math problems very tricky or very simple. His favorite are 7 and 11 because his birthday is 7/11.

Math joke: Pie are square.

Mojisola Aesher Ogunleye-Johnson, Lead Instructor

Mojisola Aesher earned his B.S. in Environmental Science and M.S. in Environmental Policy & Management at American Military University. He is also an alum of San Clemente High School and Saddleback Community College earning an Associates in History. He is currently studying to take the GRE and CSET.  Mojisola Aesher will be continuing his education in Winter 2020, taking courses in Business Administration, International Relations and Engineering/Nursing. He loves to read topics in Military History, Foreign Languages, Shakespeare, Global Folklore /Tales  and Manga. His favorite pastimes are playing guitar, visiting museums, photography, biking, watching BBC drama/crime and participating in his alma mater club activities (NSBE, MUN, Sigma Beta Delta, ATEP, Saber and Scroll Historical Society). His dream career is to be able to work independently in his passions and travel around the world. His favorite thing about mathematics is that it is in everything we see in life from patterns in nature to geometry in architecture. In September 2018 he completed Experienced Center Director training, and his CBEST Certification in December 2018.

Advice to Students: If a math topic is difficult for you, embrace the challenge!

Fun Facts: He loves dogs, foxes, and dragons!

Favorite cuisines: Nigerian, Southern, and Japanese

Math Joke: i 23 ∑ π ∴ delicious  ::  I ate some pie therefore it was delicious

OwnerJ. Steve Santacruz, Owner

 Steve graduated from DePaul University from the Honors Accounting Program with a Bachelor of Science in Accounting and later received his law degree from DePaul. One of Steve's main passions in life is teaching children. He has been a little league baseball coach since college and enjoys coaching his own two boys in baseball. Steve brings that passion to Mathnasium - hoping to influence and enrich the lives of children through nurturing a passion and appreciation for math. Most students simply need more focused instruction in order to excel. "The Mathnasium method achieves this and much more, due to the richness and breadth of the Mathnasium curriculum. It is the ideal adjunct for a student?s daily classroom instruction, whether the child is struggling or advanced." Through Mathnasium, Steve is excited about being able to teach math to children in a way that makes sense to them. He also looks forward to teaching children the importance of strong study skills, which will serve them in subjects beyond math as they make their way through high school and on to college. Steve and his wife, Karen, are busy raising two sons, Austin and Dylan. They look forward to serving your family!

Betty Wang, Director of Operations
