Bio

Do you need help in math? I can help right now. My students are children, teens, adults, and elders, across nearly all demographics, including ESL. I bring an infectious enthusiasm for math, and I work hard to make math easy and comprehensible.

I will train you at your level to help you see math with fresh, new eyes. I will work with to understand what you do know, and what you don't. From there, I will explain how the words we use and the questions we ask can be translated into math...

Do you need help in math? I can help right now. My students are children, teens, adults, and elders, across nearly all demographics, including ESL. I bring an infectious enthusiasm for math, and I work hard to make math easy and comprehensible.

I will train you at your level to help you see math with fresh, new eyes. I will work with to understand what you do know, and what you don't. From there, I will explain how the words we use and the questions we ask can be translated into math expressions and equations. (From this, you will be prepared to tackle those dreaded "word problems"!)

And as you comprehend math concepts, you will be able to solve harder and more complex equations. I am entirely confident that you will get to the level of understanding and success that you need. All I ask of you is to put in your best effort in our sessions.

I have the over thirty years of teaching and tutoring experience. I started as a tutor while in high school. I began attending the Stevens Institute of Technology, and there I received my Baccalaureate in Science as a Mathematics Major in 1989. I began to charge for my tutoring services while attending college.

Throughout the 1990's and 2000's, I was a full-time substitute teacher in the Juneau School District, in the capital of Alaska. I quickly became to go-to-guy for several teachers whenever they had planned absences. It was here, at the University of Alaska (Southeast), where I started attending formal education courses. I was also served as an employee at UAS as an adjunct professor of remedial mathematics.

In the past eight years, I taught at several charter schools in Los Angeles, while taking more education classes at the California State University (Dominguez Hills). Currently, I am a few credits shy of my teaching certificate. I look forward to achieving this and a Master's degree, even while I continue to hone my skills.

When I first meet the student, my immediate goal is to determine in which topics they are having difficulty. I speak to

Approved Subjects

Algebra 1

Algebra 1

Algebra is the generalization of arithmetic. Students have learned 2+3 and 3*5, but algebra allows for circumstances when a number is not known -- and often to solve such situations. ("I earn $350 each week, after 14% is withheld for taxes. How much should my weekly paycheck be?) Lines are thoroughly reviewed in algebra 1. I show students how linear equations occur in their lives, and how to understand both their graphs and their equations. But it's also important to understand their meaning. I explain how to understand graphs, and how to comprehend key clues.
Algebra 2

Algebra 2

Algebra 2, sometimes called precalculus, is a more complex review of algebra. Polynomials are studied in detail, specifically finding its "zeroes". I show students what the problems really ask, and the techniques to solve them. This class usually introduces trigonometry, a detailed study of circles. This course also goes into the relationship between parabolas and circles, and the equations and graphs of all conic sections.
Calculus

Calculus

Calculus is a study of how variables change -- their rate of change, to use the proper vernacular. As an analogy, algebra can tell you the average speed of a rocket ship, but Calculus can tell you its exact speed at any time, just like an odometer. I show my students how Calculus is found nearly everywhere, including in business, medicine, and nature.
Differential Equations

Differential Equations

Differential equations is the study of equations that involving one or more derivatives of functions. The differential equation governs an unknown function, which is related to its own derivates. For example: What equation's rate of change is half of the equation itself? It is noteworthy that students are often required to prove that solutions exist, and that the solutions are unique, prior to actually deriving the solutions. The challenge of this course is a fascinating and complex study, in which differential equations are self-referential. I have found that students appreciate the meta of this subject, within the equations' meaning and the process of obtaining solutions.
GED

GED

I have taught this material for years to students across the entire spectrum of competence -- and confidence. While seeming to be easy for many, this is a critical area of study for those seeking to get their GED. I show my students how they do this math everyday, and I reveal how they can adopt the practices for real life. I cover arithmetic and then the basics of algebra, along with a sense of how the number system behaves.
Geometry

Geometry

Geometry is based on points, lines, and angles. As a study of figures in "a plane", many questions can be answered very early in a geometry class using the basic concepts of a straight angle. An example is "Why do the angles of a triangle add to 180°?" (Do you know why?) Other concepts build upon this, such as: "The sum of the exterior angles of a polygon is 360°." I explain how these concepts are viewed and how viewing them in right order shines light onto the entire course.
GMAT

GMAT

If necessary, I cover the format of the GMAT and the question types of the Integrated Reasoning and Quantitative Sections. Then I explain specific strategies for the different question types, which we return to as we cover both the math fundamentals and specific questions. In particular, several question types are reviewed in depth, since many are likely to occur once.
GRE

GRE

To do well on the quantitative sections of the GRE, you must know more than just the mathematics of algebra and geometry. The newly revamped test has four types of questions on the Quantitative sections. These questions will require out-of-the-box thinking, beyond the skills taught in high school. I have been reviewing these question types, and have found strategies for them. Along with the math, I will teach you the format and how to successfully navigate the questions you that will confront you.
Microsoft Excel

Microsoft Excel

Arguably the single most important software ever developed, the spreadsheet is indespensible in any business endeavor. Its applications are extraordinary, and powerfully revealing information can be gleaned from data by even a moderately experienced user. I explain the very basics of MS Excel, including proper keyboard use so students learn quickly and efficiently. Then I teach "cut, copy, paste" along with basic functions, and how to quickly fill a column or row with data. Other functions are taught to collect and alter data, and formats are explained to show information in nearly any way imaginable.
Prealgebra

Prealgebra

I help students understand prealgebra by reviewing the basics of arithmetic and introducing concepts of generalization. For example, imagine you travel 4 mph faster on your bike than I do on mine. What speed are you going if I am going 12 mph? What's my speed if you're going 9 mph? These sorts of questions introduce concepts to students, concepts that build to the idea of a variable, a letter that is used for any unknown number.
Precalculus

Precalculus

Precalculus is Algebra 2 or Algebra 3, because it includes the final study algebra prior to Calculus. Polynomials are studied in detail, including finding real and complex "zeroes" from Descartes' Rule of Signs. Also studied is trigonometry, the study of circles. I teach this in very clear terms, using circular props so students can visualize the sine and cosine waves. This course often ends with limits and an intro to the rate of change of a function, such as speed.
SAT Math

SAT Math

I have taught the Mathematics portion of the SAT numerous times in the past, to groups and individuals. (I have created a workbook to assist students, which I am currently updating.) If needed, I first focus first on the format of the exam, and how to take advantage of the question types. Then I go over the content and the math needed to understand. Throughout, I discuss solving strategies with the student, so that they understand what to expect and how to approach the questions.
Trigonometry

Trigonometry

Trigonometry is a detailed study of circles. Imagine a point on a circle, as the circle slowly turns. How does the point move as the circle moves? What is its height from the center, and left-right distance from the center? The study of trigonometry often involves graphing trig functions, the study and graphs of inverse trig functions, and trig identities. I explain these concepts and others in a straightforward manner, so students can see the basic functions and why they are studied.

Sean is great with teenagers

Sean is tutoring my 17 year old who has never liked math. She is actually understanding and beginning to realize that she can do this. Sean is excellent at presenting without talking down to her and stresses the positive and her taking responsibility for her education. I've used multiple tutors over the years and Sean is the best.

Phil, 11 lessons with Sean
Tutor responded:

Thanks so much, Phil!! Your 17-year-old has really begun to recognize the value of her own education, and is a pleasure to work with.

Engaging, energetic, and knowledgeable

My son and his cousin have had two sessions with Sean thus far. His tutoring style is engaging, upbeat, and focuses on topics that the learners indicate are areas of difficulty. Sean is professional but not stuffy and very accommodating. Our family will continue working with Sean and I strongly recommend his services.

Tutor responded:

Thank you so very much, Charles. I really appreciate that you recognize that I try to be accommodating...

SAT preparation and High School Math Tutoring

Sean is preparing my son for my upcoming SAT in Oct and helping Jonathan with his pre-calculus class. I believe Jonathan will do much better on the next SAT. Jonathan feels more prepared and confident. Sean is working so hard with my son to reach his dream of getting into a highly completive engineering college. Sean is a knowledgeable, patient and caring tutor. Especially in preparing Jonathan for the SAT and assistance with his pre-calculus class. Sean knows how to relay subject matter to children and teenagers at their capability in such a way that they understand what he is teaching with clarity. My son looks forward for the next tutoring session.

Mordy, 2 lessons with Sean

Sean S. is an excellent tutor.

Sean is a patient and methodical tutor. His knowledge of Algebra 2 is excellent. My son got a lot out of the session. I would certainly recommend Sean to others and will use him in the future.

Tutor responded:

Thank you so much, Howard!! Your son made was an excellent progress during our session. I believe that his listening skills will serve him well...

Patient and thorough tutor

Sean has been a real help in boosting my daughter's confidence in Algebra. He takes his time explaining concepts thoroughly to make sure she understands something before moving on. Prior to the tutoring sessions, she was panicking and worried that she would not catch up. Now she is feeling confident in her abilities and understanding of the subject. I highly recommend Sean as a tutor.

Kate, 1 lesson with Sean
Tutor responded:

Thank you so much, Kate!! Your daughter works very hard to be a diligent student. It's always a pleasure to tutor her and watch as all the pieces come together. I genuinely hope that she is aware: with this level of work, she'll do extremely well with whatever she chooses in her life.

very knowledgeable tutor

Sean did a great job tutoring me!! We went over my review packet for my upcoming math test, focusing on area under the curve and derivatives. He was very good and patient when I didn’t understand.

Anna, 1 lesson with Sean

Patient tutor

I have had three classes with Sean and plan to take a few more. He is very professional and has so far been a life saver. I have struggled with excel for years and the one on one classes have helped me tremendously. As a professional in the business world, the refresher in math with the excel will be invaluable for any working environment.
