Knowledgeable and patient

Ephraim has been a great tutor for my son who is currently moving up to 8th grade, he has prepared him for AMC 10, algebra 1 honors, and geometry honors recently. My son was initially struggling in 5th grade, however, he is now excelling and excited to do math. He is motivated to go to his lessons and enjoys it so much, that I don't even have to remind him to go to lessons. Ephraim explains the material very well and is very patient with children. I highly recommend him.

Exceptional math tutor

It has been about a year since we have been studying math with Ephraim. Our primary focus is to go over Algebra and to prepare for math competitions including AMC and Mathcounts. He is very knowledgeable about how to prepare for the test and exceptional at identifying areas of weakness to explain things clearly. He always steps through any questions or areas of doubt before moving ahead. My son got a great outcome from the recent MAP test on math and he is confident that he is well prepared for upcoming math competitions. Not only from an academic perspective, Ephraim is exceptional at communicating with and motivating young adults. Ephraim has made the tutoring experience enjoyable and my son loves math even more than before. We highly recommend Ephraim to all students!

Extraordinary GMAT tutor

Ephraim is an extraordinary GMAT tutor. He’s the right tutor for the business school applicant who fits any of the following criteria: 1. Values their time and wants to approach the GMAT as efficiently as possible 2. Hasn’t done math since high school and needs to revisit the fundamentals 3. Is seeking a perfect score Ephraim breaks things down so that you understand WHY the answer is right. He’s been teaching math so long, and from so many different perspectives, that he knows the best/fastest way to teach any topic you throw at him. Plus, he’s super encouraging all the time and made relearning math for the GMAT a genuine pleasure. If for whatever reason I need to get good at math again, I’m calling up Ephraim.

Knowledge and dedication

Ephraim is the best math teacher I have even known. Having been teaching my high school daughter for about a year. It’s our fortune to have him in my child’s education experience. He’s knowledge, dedication, and passion is remarkable.

Happy to have found Ephraim.

Ephraim is very organized and responsive, he took the time to find details and information that he would need to help my son be successful during the tutoring and in my son's math class, as well as competition math. My 12-year-old son enjoyed his first lesson and found the time spent with Ephraim extremely helpful. My son is looking forward to the next lesson with Ephraim.

Mr. Ephraim is a great fit for my children

I have been using Mr. Ephraim weekly for my daughters’ math tutoring needs. One is an advanced math student and the other is slightly above grade level. He fills the gap between their school lessons and where they need to be to be competitive with other ambitious students. He is patient, kind and conveys a genuine love of teaching mathematics. I can’t wait until my son is old enough for Mr. E. in a couple of years! He is a refreshing change from the uni. student math tutors, who tend to be fine for cramming for an upcoming test but aren’t up for giving a deeper treatment of math topics.

Ephraim is very kind and nice. He was able to identify my weaknesses and help me understand how I can go about overcoming them. I really appreciated his help. I definitely recommend and will use him to tutor me again!
