Head of BümoBrain
Virtual School

Having started a K-12 education company, Nguyen has a passion for education that has evolved tremendously. After graduating summa cum laude, Nguyen started a budding education service that grew into an INC5000 educational enterprise. In her former years, she worked with a wide range of students from all over the world in academic instruction, test preparation, and college admissions.

A well-known college consultant, Nguyen has placed some of the brightest students into the top universities, such as Stanford, Caltech, Yale, among many others. However, in recent years, Nguyen has been hyper-focused on the world of early childhood education.

As a mother of two toddlers, this intrigue transformed into a true passion for early childhood learning. Thus, Nguyen co-founded BVS as a robust resource for parents and children who desire to learn through exploration, imagination, innovation, and creativity.
