To Whom It May Concern:

As a former student of David Grinstein, I am pleased to write a letter of recommendation on his behalf.

Last semester (September – December) while attending Curry College Continuing Education program, David provided tutoring services to me on a twice-a-week basis for Statistics. I previously had taken Statistics three years ago and struggled throughout the semester and failed. In my current position, I am a Manager of a HR Department for a major corporation, but knew that I would need the assistance of a tutor to pass Statistics, which is a very difficult subject for me to grasp and understand.

Upon my first tutoring class with David, I felt that I made the right decision in having David as my tutor, as David took a sincere interest in asking me questions about my education and approached teaching Statistics in a very calm manner. David was always timely, prepared for our two hour session, patient with me and extremely knowledgeable with explaining and teaching me Statistics. In addition, with all of the varied homework assignments David always was able to breakdown the lengthy task of problem solving to me in a manner that I was able to work through understanding how to approach problem solving with Statistics. At the end of the semester, I achieved a B-, which I know I never would have obtained without the tutoring sessions and support from David.

I would highly recommend David as a tutor.

David Grinstein is a wonderful tutor. Mathematics has always been my weakest skill and I was signed up to take the GRE, and had a month to study. David is extremely knowledgeable and very articulate. I was easily and quickly able to understand the concepts that I had previously struggled to comprehend. David was very patient with both my lack of knowledge and comprehension in the field, which allowed me to quickly pick up on the mathematical concepts that I needed to know for the test. David offered many methods for both learning and recalling the material, which was particularly helpful for the GRE. Working with him was a pleasure and each meeting was both informative and enjoyable. I was surprisingly pleased with my score, and would not have been able to succeed without David’s help.

To Whom it May Concern:

I highly recommend David Grinstein for tutoring in Math. He taught my son, who is in high school, Algebra, Geometry and also helped in English.

David has a wonderful rapport with people of all ages, especially children. He also helped my younger son who is in middle school, in math. His ability to connect with his students and his talent at teaching simple concepts, as well as more advanced topics, are both truly superior. He has good written and verbal communication skills, is extremely organized, reliable and computer literate. He designed course of study for my kids while we went on vacation (out of country) for a month. David can work independently and is able to follow through to ensure that the job gets done. He accomplishes these tasks with great initiative and with a very positive attitude.

I recommend David to you without reservation. If you have any further questions , please do not hesitate to contact us.

David G was a great tutor, he was very patient yet very thorough. He explained things very clearly

was very reachable and available. If there was anything he didn't understand during the session, even if it was the smallest thing, he would review at night and email me back a response very quickly. He didn't just tutor me, he basically taught me the course and is also very nice guy!

To Whom It May Concern,

I would highly recommend David Grinstein as a math tutor.

He tutored my son who is in high school for Geometry. We

Definitely made the right decision. When I seen my son was

Struggling with the Geometry we immediately called David.

He came to our house and broke down every problem explaining

in a manner that my son could understand and comprehend.

My son went from a C to an A the very next semester. David is

Caring, patient and extremely knowledgeable and without his help

My son would not have succeeded in Geometry. He makes math


I am honored to recommend David as a tutor! Please do not hesitate to call us with any questions.
