I’ve been tutoring since 1998 when I started helping my high school friends with their math homework. After that, I tutored for a national tutoring company for about five years until about 2005. Around that time, I struck out on my own, and provided in home math tutoring to middle school, high school, and college students for several years until 2008.
Today, even though my career has taken me away from tutoring full-time, I continue to tutor math because it is one of my favorite subjects, and because helping people is one of the most rewarding ways to spend my time. It is a really meaningful experience for me when I can help someone get to that point where the ideas finally click into place, and s/he is able to see how concepts that at first seemed disconnected, in reality actually fit together perfectly as a whole.

Educational and Tutoring Background
I first went to work for a national tutoring chain once I had completed my A.S. in Mathematics. I have completed other degrees since then, in other subjects, including two advanced degrees in business. I am also in the final weeks of completing a law degree.
I taught math with a national tutoring chain for about five years, and became certified by them to teach all of their math programs. I have taught Pre-Algebra, Algebra 1, Geometry, Algebra 2, Trigonometry, Pre-Calculus, and Calculus as a private tutor since 2001.
I completed math classes at the university level through advanced calculus. This includes two semesters of elementary calculus, vector and multi-variable calculus, courses in linear algebra, differential equations, analysis, complex variables, number theory, and non-euclidean geometry.

Your Pre-Algebra class introduces you to new concepts such as expressions of multiple operations, basic equations, variables, graphing, and some pretty heavy duty arithmetic. In this sense, Pre-Algebra solidifies what you have previously done with arithmetic, and prepares you to go on to Algebra. While it’s true, that most of the types of calculations that you will perform in this class can be done by calculators, the reasoning that you learn in this course will make sure you know what to do with the calculators. This is important in its own right, even if you do not plan to go on to Algebra. It ensures you attain problem solving fluency in working through any arithmetic scenario, which is invaluable as a life skill.

In high school, you may encounter Algebra 1, Algebra 2, and even Algebra 3. In college, you might encounter courses like Beginning Algebra, Intermediate Algebra, and College Algebra. What’s the difference between these courses? They are all algebra in the sense that they deal with tools and techniques for solving equations, simplifying expressions and, to a basic extent, analyzing functions. What’s different about the courses is that the level of rigor increases as you advance, as well as the sophistication of the methods you use will presume you’ve attained a certainly level of understanding and proficiency with the fundamentals. Not unlike an English class, you continue to study the subject of Algebra semester after semester, and become progressively more sophisticated in the process.

A whole class is typically devoted to Geometry in high school, but less often is it its own course in the college curriculum. The essentials of the course are absorbed throughout the algebra curriculum in college, as well as a Trigonometry or Pre-Calculus course. In high school settings, the class allows students a year to digest the concepts they learned in their first year algebra course, as well as learn the logic of proofs, and spatial relationships of angles, lines, and polygons. Students will typically learn the Pythagorean theorem for the first time in this course, as well as encounter the basic trigonometry ratios that allow information about the triangle’s known sides and angles to be used to extrapolate information about unknown sides and angles.

Pre-Calculus, whether encountered in the high school or college curriculum, could be (and often is) referred to as an introduction to analysis course. This course basically assumes students have largely mastered their algebra from prior courses and now plunges into how to analyze functions that includes how to describe any patterns of behavior, such as repeating or oscillations, and end behavior of curves. When we do that we encounter the concept of describing what happens to a function as it approaches infinity for the first time, and we develop tools to describe the different ways that curves behave as they tend towards infinity.

Calculus courses in college are typically three semesters, the first two of which are single variable calculus, and the third semester is multivariable (and vector) calculus. In the high school setting, the course is usually an Advanced Placement course (AB) or two (AB and BC), and range in length from one to two years to cover the same ground that is usually covered in the three semesters of college. This course builds on the analysis ideas from Pre-Calculus but adds a new device to do so — the limit. The limit allows curves to be analyzed at the infinitesimal level at any given point to determine its behavior. It allows for exact calculations of areas under curves, as well as the calculations of infinite series. These tools are the foundation for describing scientific phenomena, especially in engineering and physics.

Because of your help, my son earned a 105% on his latest math quiz! His interim grade was 60%! He enjoys the time with you!
"Great tutor." Keith was extremely helpful in helping our daughter who was struggling in PreCalc. He only came a couple of times to help her get the concepts on an upcoming test. His help was very significant and our daughter got a 93 on that test! I would highly recommend Keith as a tutor.
"Patient and very knowledgeable with algebra concepts." Hello everyone. I would recommend Keith R. as a tutor for you, especially if you have challenges with algebra. He was very patient when helping me understand my algebra homework. I have not worked on algebra in over twenty years and it has been quite challenging for me to recall and comprehend these concepts again. I appreciate Keith's help with putting me on the right track.
"Beautiful work. Everything looks great: all work steps were shown; work was done neatly and in order." This is actual feedback from my college professor, and your help helped make this possible! =)
Your answer to my question was perfect. Thank you! And the reference video you gave me was extremely helpful.
Couldn't have asked for more! Thank you!!!
Just amazing help! THANKS!!!
Very thorough and informative help! Cheers!
Five stars! Very thorough, lovely feedback!
I love you guys!
Thank you for helping me so much. You really made a difference in my grades!
Thanks for everything you've done for our daughter Jessica. She said her other tutors have been nice, but you are especially cool!
