I highly recommend him as a tutor for all levels of math and mathematically based sciences.
Keith has been an incredible math teacher for my daughter, helping her get two years ahead of grade level.
He is professional knowledgeable and all of this with one of the best positive attitudes I have run across in my life.
Mr. Offen tutored my 6th and 8th grade children and was always professional, knowledgeable, and dedicated to his work.
He has been teaching my daughter math and calculus, and we have been extremely impressed with his professionalism, patience, and dedication.
