"I have been working as a Substitute Teacher for a while. I teach Math and Science classes in middle school and high school. I support middle schools and high schools both in West Sacramento and Davis Joint Unified School Districts. Math and Science subjects are the two subjects that many students (about 90%) does not like and I would like to change the mentality. Both Math and Science subjects make up the entire universe. Students have to be very good at both subjects in order to compete in the real world.

Teaching is my passion. I started teaching when I was very young. In my early career, I taught Police General Order and Penal Code in the police force. Especially in Math, I hope that I can help one student (at a time) to discover the fun in learning and using Math.

I spent better part of three (3) decades (from 1984 to 2009) running a successful electronic company. I also served as one of the Chief Scientifics in the company. I have authored and co-authored many technical papers. I used Math and Science everyday on the job. I have been constantly helping my colleagues in answering fundamental Math and Science questions.

The universe is huge. If you do not have a college degree, you will have a hard time to find a good paying job. I will like to help you to success. I was invited to attend many high schools graduation ceremonies, and at almost every high school where I was invited, about 30% of the senior class is going to on to a four-year university/college. Please prepare yourself early so that you can attend a four-year university/college." less...
