Bari Kahar, Owner/Advisor, Ed.D. Candidate, PENN CLO

Mathnasium Mastery Certified - Center Director
Favorite number: 39. Something funny about math: Life is all about numbers and organizing them. One life philosophy that you want every student to learn: Always get done the easy and simple math done in your math test first. Academic background: Masters in Education Leadership, Public Policy, and International Development from the University of St. Thomas, Bachelor's in Computer science from Minnesota State University. How you fell in love with math: When my eighth-grade teacher Mr. Kashem taught me how to always score better math scores. He has been a school district parent and community educator since early 2000. With his three sons Aver, Reevu and Ray he is a busy parent always. He even gets busier, when 140 other parents are asking him to develop their kids' love for math. His mission is to make the after-school additional Math learning experience as fun and accessible as possible to the 20, 000 students around him.

Irina Kahar, Owner/Principal Instructor, Ph.D. in Computer Engineering

Mathnasium Certified - Center Director
Irina's favorite number is 6. She has a PhD. in Computer Engineering from Wayne State University in Michigan. She has taught students in High school, College, and Universities for more than 15 years. Currently, in her full-time role, she is a Data Management Specialist at Mayo Clinic. With three sons, Mathnasium is something she enjoys on the side. Irina thinks a mathematician is "a blind man in a dark room looking for a black cat which isn't there." One life philosophy she wants every student to learn: whatever happens in life, happens for something good. She fell in love with math doing Algebra.

John Stokesbary

My favorite number would have to be the golden ratio (about 1.62) since it has such a strong connection to the natural world. Some things I enjoy doing are playing tennis, making music, and learning about trees. I’ve always loved math, with its major connection to physics, engineering, and the natural world as a whole, and am so glad I have the chance to share my enthusiasm with others!

Gwen Lindahl

Gwen is a part of a variety of activities including robotics, band, choir, and speech. She also enjoys the outdoors, hiking on family camping trips is always a summer highlight. Gwen's favorite number is 13, and she has a passion for teaching others and watching their math skills grow.
