About Tim


Bio

Hello! My name is Tim. When I was in college I tutored in the library and found out that I liked it and wanted to become a teacher! This was in 1980. I graduated from the University of California at Riverside in 1983 with a degree in Chemistry and a teacher credential. I have taught science and math in grades 7 through 12. Most recently I taught high school Chemistry and Pre-Engineering.

In the last couple of years I have had experience with online teaching and tutoring. ...

Hello! My name is Tim. When I was in college I tutored in the library and found out that I liked it and wanted to become a teacher! This was in 1980. I graduated from the University of California at Riverside in 1983 with a degree in Chemistry and a teacher credential. I have taught science and math in grades 7 through 12. Most recently I taught high school Chemistry and Pre-Engineering.

In the last couple of years I have had experience with online teaching and tutoring. At first it was difficult to get used to working with students that way, but I learned and now I get as much satisfaction out of it as I did when we were in the classroom.

My main subjects to tutor are Chemistry and physical science. I have also tutored recently in Physics, Algebra 1, Algebra 2, and AP Chemistry. I really enjoy my subjects, and I believe that science and math are the most important courses a student should take! (I know other teachers believe that about their courses, but of course they are wrong :) ) Join me and we’ll get through your courses together!

Algebra is one of the most important courses you will take because you will need it in high school and college science courses. When I teach or tutor Algebra I want to make sure the student understands the basics, so I explain it so the student understands the underlying concepts, not just the steps to getting the right answer.

Science tries to understand the universe around us. When I teach or tutor science I include real world examples of the concepts, so the student can relate to it on a more personal level.

Excellent/Patient Teacher

He is an excellent teacher. He is pleasant, patient and clear and interacts well with the student. I highly recommend.

Very Knowledgeable and Experienced Tutor

We highly recommend Mr Tim as an exceptional maths tutor. Over the past three years, he has worked closely with my boys, and the improvement in their mathematical ability, confidence, and overall attitude toward the subject has been remarkable. Mr Tim has a great way of explaining concepts clearly and patiently, ensuring the boys not only understand the material but also feel confident applying it independently. He takes the time to adapt his teaching style to suit their individual learning needs, which has made a real difference in their progress and results. One of the things we appreciate most is his flexibility and commitment. He has consistently gone out of his way to accommodate last-minute requests and changes in schedule, always making himself available when extra support is needed. His reliability and willingness to help, even at short notice, truly set him apart. Beyond his teaching ability, Mr Tim is encouraging, supportive, and genuinely invested in his students’ success. He has helped Jayson and Warrick build strong study habits and a more positive mindset toward maths, which will benefit them well into the future. We are incredibly grateful for his dedication and the lasting impact he has had. Mr Tim is highly appreciated, and we would not hesitate to recommend him to anyone looking for a committed and effective maths tutor.

Wonderful tutor!

My 15 year old feels Mr Tim is patient and extremely helpful. She is more confident after her first two sessions and will absolutely be scheduling more with him in the near future. Highly recommend!

Finally found an amazing Chemistry tutor! We highly recommend Tim R.!

Tim was extremely helpful in preparing my high school sophomore for her Chemistry test. Tim patiently worked through the content while offering helpful tips to explain difficult concepts. They covered the electromagnetic spectrum, wavelengths, and frequencies, calculating frequency given the wavelength, the photoelectric effect of light, and finding electron configurations.
