"I want to share a wonderful experience my two daughters, aged 7 and 12, have had at the after-school math improvement program they attend. The staff at this program are simply the best, with one standout being Chris. He is not only a fantastic teacher who has helped my daughters immensely with their math skills, but he is also the nicest person you could meet. Chris's dedication and passion for teaching truly shine through in his interactions with the students, and my daughters have benefitted greatly from his expertise. I highly recommend this program to any parent looking to help their children excel in math."
