About RSM-Wellesley:

RSM-Wellesley is conveniently located on Washington Street in Wellesley Hills, just off the intersection of Routes 9 and 16. 

Opened in 2011, the RSM-Wellesley math school now serves more than 300 students from Wellesley and the surrounding communities of Weston, Newton, Dover, Needham, Wayland, Westwood, Medfield, Lexington and Natick.

As a branch of the Russian School of Mathematics and a campus of RSM-Newton,  our mission is to help our K-12 students build a solid math foundation and develop lifelong critical thinking skills.  We do this through a combination of great curriculum and exceptional teaching.  Being so close to Newton, we are fortunate to be able to draw heavily upon the experienced teaching staff of RSM’s Newton headquarters.

About the Campus Principal

Angela Dzhitenov, Campus Principal

Angela Dzhitenov

Education: M.S. in Computer Science and Applied Mathematics, University of Latvia

After graduating with a Master’s in Computer Science and Applied Mathematics and working at the Academy of Science of Latvia (Institute of Electronics and Computer Science), Angela took a detour to spend some time working as a graphic designer in advertising. Her love of math pulled her back to work for RSM, where she has been an avid teacher for the past three years.

Her two children are RSM students and her oldest son is graduating from the Queen Mary University of London with a focus in Theoretical Physics, something she is proud of and feels demonstrates the success of the RSM approach. She feels that the RSM curriculum is an invitation for students to think and explore. Instead of focusing on teachers providing solutions, she highlights that RSM thrives by training students to find their own solutions independent of outside instruction. One of the best advantages to RSM that Angela has found is that student challenges are adjustable at the earliest stage of education onward, making one kind of problem applicable to higher levels with simple tweaks. This model offers a new way to enjoy math, by creating excitement in collecting and organizing knowledge into digestible information.

Angela is excited to become the Vice Principal for the RSM-Weston branch in Massachusetts and is taking over as Vice Principal of Wellesley this Fall, with the hope to expand the availability of the supportive and nurturing RSM environment.
