In-person lessons

Dave is the most professional, patient and thorough tutor, going the extra mile to complete a day's lesson or to ensure the concept is understood. We have been using Dave for almost a year, first for Geometry and now for Algebra II. I cannot begin to express what a gem he has been.

David did a great job in explaining concepts and problems that I was struggling on before I had our first lesson. He is very patient, and is really good at breaking things down so that you end up owning it. I'm excited to keep working with him to achieve that A that I'm shooting for this semester!

David helped me prepare for some homework and an exam on arithmetic and geometric sequences, summation notation, and binomial theorem. I felt much more confident in these topics after our session! Highly recommend!

David is remarkably knowledgeable and patient. He provided same day tutoring for my 14 year old with pre-calculus. My son took to David's methods immediately and was actually smiling doing his math, which has not been the case for sometime. We look forward to future sessions!

"Mom, David is a math genius".that's what my daughter said to me.Thank you David for tutoring my daughter.We are super lucky to find you.

David really took the time to understand my questions and problems. He taught me in a way that I could understand and tried not to complicate things. I highly recommend him.

I am Miguel's Father. After the first meeting I noticed a big confidence change in Miguel, Miguel had taken calculus 1 before and got a D and he repeated the class this semester in the first test he got a C, after that is when he started getting tutored by David, next test he got a B and the 3rd test he got an A, Miguel met with David the day before finals to study so we're still waiting for final results. I met David that day and saw how he tutors, I like how calm and patient he is and how he knows his stuff he was not trying to figure out how to do the problems. Miguel will take calculus 2 in the Spring and he says he will see David whenever he needs help.

He has been able to check my son's foundational knowledge in algebra 1 and 2. His ability to observe, question, and challenge my son's knowledge/skill is apparent and invaluable in giving my son instructions that improve his capabilities. We will definitely continue to hire Dave in the future.

David has been an amazing math tutor! He has take a "math-a-phobe" like me and made be believe in myself and abilities to do the work. I actually enjoy math now and although it is still a challenge I am no longer scared of it. I would not hesitate anyone from using Dave because it is that good. Worth every penny and more!

David is wonderful! He was able to teach my son to understand complex mathematical concepts in a timely manner with a great sense of humor.

He gave me new perspectives on basic arithmetic and pointed out my bad habits that hinder me as i work through a problem.

It had been five years since my last math class, and David U. helped me get back up to speed with all of my trigonometry, geometry and advanced algebra in record time by teaching me effective ways to remember all of that information (instead of just memorizing it.) He was able to see where my weaknesses were and even dropped off extra practice problems for me to do. This alone made the difference in a whole letter grade on my midterm. I ended up passing Calculus II with a B! Thanks David U. for all of your help.

Thanks, Rachel! I'm glad my tutoring helped, but the lion's share of the credit goes to you. You worked super hard this summer, and together we accomplished a miracle! All the best to you in your future studies.

Different 'tricks' to complete complicated word problems, such as mixture and distance problems. Also, very patient and willing to work with an admittedly fatigued student.

Thanks, Nick. I look forward to working with you again.

I have met with David for two sessions so far. I am currently struggling in my first Calculus course and he has been a monumental help in first pinpointing my strengths and weaknesses, and then helping me work on exactly what I need for improvement. He immediately noticed that my issues with math stemmed not from Calculus, but from my core algebra skills which he got to helping me with right away. He is incredibly easy to work with; his space is quiet and easy to concentrate in, and, so far, each time I've left I've felt better about what I was working on than before. I look forward to working with him again in the future!

David really knows calculus, and he has been able to clarify for my daughter exactly where she is making mistakes, and what she needs to be careful of. Definitely worth the investment- my kid would not be spending her Friday afternoons getting pre-calc tutoring if she did not feel like it was really helping her.

Thanks, Teruko! Your daughter is a very sharp student - the kind who's not satisfied with memorizing formulas, but works to understand them on a gut level. Working with her is a pleasure!

David is a great tutor. I think I threw him a curveball with Discrete Math, but he was excited and picked it up like riding a bike. He definitely knows his stuff. He is very respectful and not pushy at all. I could have been more prepared, but we just opened up the book and started getting to work. I recommend David, no problems!

Thanks, Mike, for your kind words. You're a nice guy too!

This was my third session from Dave and he has been an amazing help with my calculus. He has also gone above and beyond to give me a few other tips on some of my other subjects. Thanks Dave!

We did calculus 2, and it was a tough subject and he taught me very well with a few tricks and I passed my exam with flying colors. HIGHLY RECOMMENDED, WORKS WELL with you to understand it.

Thanks, Joe, I couldn't have done it without you!

David is a great Math tutor. He is gifted in the area of Mathematics and is able to clearly explain concepts to those of us who aren't.

Thanks, Teresa! Always a pleasure working with you.

Dave has worked with my high school Senior for the last few months preparing him for the standardized tests. Dave has focused on the strategies in all the Math concepts that were long forgotten and really helped him in the Tests. Dave responds better by phone (no Texting) than computer in the end. He's very patient, on time and really knows his material through Calculus.

Thanks, Vicki! Working with Alex has been a pleasure.

Approved subjects are in **bold**.

In most cases, tutors gain approval in a subject by passing a proficiency exam. For some subject areas, like music and art, tutors submit written requests to demonstrate their proficiency to potential students. If a tutor is interested but not yet approved in a subject, the subject will appear in non-bold font. Tutors need to be approved in a subject prior to beginning lessons.

The CBEST is an exam that's not very difficult. The math it requires is mostly just standard algebra and geometry. Any decent math tutor is sufficiently knowledgeable to tutor for this test.

In my case, I have 30 years of experience in tutoring not only algebra and geometry, but also trigonometry, calculus, differential equations, statistics, number theory, and more. I have also tutored specifically for the CBEST on a number of occasions. I am highly qualified to tutor students needing help in preparing for the CBEST exam.

I look at differential equations as a game, and that's how I teach it: This is the objective, these are the rules, here are some helpful tricks you can use. This approach certainly worked well for me in my own studies; when I took a course in differential equations on my way to earning the degree I hold (a B.A. in Math), I understood the material so well that I scored 100% on every exam, including the final.

Likewise this way of looking at differential equations seems to have worked well for the dozens of differential equations students I have tutored over the past 25 years. A good many of them have enjoyed excellent outcomes, mastering the material well and achieving high grades in their courses.

It worked for them, and it can work for you too. Treating differential equations as a game makes it fun and easy!

Discrete math includes topics such as summation with sigma notation, mathematical induction (both weak and strong), combinatorics, and graph theory. These are all subjects I have studied extensively in a variety of settings: in courses I took on the way to receiving my bachelor's degree in math, in my work over the past 30+ years tutoring students who were dealing with these topics in their courses, and privately just for my own pleasure. I have already enjoyed considerable success tutoring these topics outside the WyzAnt system, and I am eminently qualified to pursue these topics with WyzAnt students as well.

A linear algebra course typically begins by considering matrices as a tool for solving systems of linear equations, which is a fairly mechanical process, and then progresses to the very abstract realm of vector spaces, in which a "vector" need not involve numbers at all, and "addition" and "multiplication" may be defined as something completely different from the familiar arithmetic operations we've used all our lives. Working with this latter type of problem requires thinking outside the box. That's something I'm good at, which is why I was able to sail through the three Linear Algebra courses I took on the way to obtaining my B.A. in Math, earning A's in all three of them. I've had a good deal of success as well in helping my own Linear Algebra students master these skills, during the 25 years or so that I've included that subject in my work as a professional math tutor.

Both aspects of Linear Algebra, the more mechanical operations and the more abstract problems, are important. Both by my academic training and through my accumulated experience as a tutor, I am well qualified to help students achieve mastery in this fascinating yet sometimes challenging subject.

I have been a professional math tutor for more than 30 years, and in that time I have tutored a number of students in the area of Symbolic Logic; currently I am in the process of writing an Introduction to Symbolic Logic. Logic has always come very naturally to me; I began studying it when I was 12 years old (which was a long time ago!). In the course of pursuing my bachelor's degree in Mathematics, I took (and earned A's in) two separate courses in Logic, one offered by the Math department and the other by the Philosophy department.

Some of the topics covered in those courses were: Logical statements and truth values; negation; conjunction, disjunction, and implication; truth tables; De Morgan's Laws; syllogisms; conditional statements and the inverse, converse, and contrapositive; proof by contradiction (a/k/a indirect proof, reductio ad absurdum); logical equivalence and the biconditional; proof via truth tables; tautology; contradiction; and paradox (including the Liar Paradox and Russell's Paradox). I am well qualified to teach all these topics, and more.
