Introducing Sigma Mathematics

IMG_4550.JPG

Teaching has always been my passion. I love tutoring many different areas of math to all age groups of students. I also enjoy creating learning plans to suit individual students' need. My goal is to make math learning easier, interesting and more comfortable for each student. My reward is the “I get it now!” moments with my students.

The Tutoring Service You Can Depend On

We think learning math is like building blocks. The stronger you build the foundation, the higher you can build on top. Sigma Mathematics helps you, or your child, build a sturdy math foundation and support the building process at every step. 

We offer one-on-one and small group tutoring so that we can design the best lessons for each student. The lessons can be at your desired locations at your desired time.
