About Clifford K.

****Dr Cliff requires that you contact him through the Ask-A-Question feature prior to booking lessons with him. Please be sure to provide him with the following:

-Skill Level
-Schedule request.

'Dr. Cliff,' a part-time college/university professor, teacher and tutor with 5 master's and 3 doctoral degrees in a variety of topics: Mathematics, Computer Information Systems, Computer Science, Management Information Systems, MBA, Leadership, Education and Administration. He has always used proven educational techniques to instruct undergraduate students, graduate students and school children/teenagers (K-12). In addition, Dr. Cliff is a Certified Tutor by American Tutoring Association and National Tutoring Association (Math); he holds California Teaching Credentials in Math (CSET I,II,III), Business (I,II,III), and Educational Technology/Computers (I,II); he is a Sylvan Certified Teacher in Math and Arts/Language K-12.

Dr. Cliff believes that, although many professors and teachers do an admirable job in the classroom, many students and children do not learn well in traditional institutions. Many students and children don't respond to the assembly line nature of most institutions. He believes that a student's or child's strengths and natural abilities need to be the foundation of learning. Dr. Cliff often warns against a "cookie cutter" approach to educating students, teenagers and children. You or your child is seen as an individual, and natural strengths are identified and built upon. Therefore, individual one-on-one tutoring or help is the key approach to each student who has any challenges difficulties in a given subject.

In today’s environment and economic challenges, with shorter budgets for the education, larger classes sizes and pressure of performing well in all kind of standard tests, I often see many students lacking true knowledge and skills in a given subject, since they cannot get individualized attention during the class session. That’s where a tutor comes into the picture, not only uncover major “holes” in students’ knowledge set but also teach students how to study, how to learn and through proper guidance “fill” those knowledge and skills holes.
