Lesson Details


Levels Taught:
Middle School, High School, College

I have dealt with geometry for years and can help you master it as well! Math is very much a language and learning to speak it is not so daunting with the right teacher. I am that person.

I have dealt with geometry from middle school to the present because my degree in physics entailed a lot of geometry. You want someone who has worked heavily in the subject and is good at teaching students to help you master the material comfortably!

I work with students through material, practice problems, test/quiz prep, teach supplemental lectures from unclear lectures in class, and write practice materials for my students! Let me help you master this topic to meet your goals.

Shoot me a message to tell me your goals and I'll help you meet them!

Teaching since:

Teaching is what I do! I have TAed multiple classes and taught dozens of students. I teach piano and other music concepts, as well as STEM fields in school. I only teach concepts that I'm completely fluent in, however, so you always get the absolute best instruction possible!

I have been playing piano for over 12 years. I retrained from scratch in the Taubman Technique a few years ago and play with ease and effortless musicality! I have taught tons of students how to play the instrument, incorporating these concepts into their playing as well.

I also tutor in STEM topics, including all math, physics, chemistry, and others. I have tutored over 2 dozen students and helped many achieve great results. I have a Master's degree in applied physics, graduated Magna cum Laude, and am fully prepared to help you master your math/science classes!

Schedule a lesson with me! See yourself improve from someone who knows how people think and understands the topics enough to impart the same onto you!

Alex is extremely passionate when it comes to teaching piano. He breaks down music theory in a way that you can understand, allowing you to take that knowledge to learning pieces all by yourself.

Excellent first lesson. I am excited to work with Alex. He seems very knowledgeable and was able to show me some very good techniques that will immediately help me improve my playing.

Alex is fantastic. As a student, it's obvious he's had years of experience dealing with the material taught, and he explains problems in a thorough, well-contrived manner. Since beginning these sessions, my grades have risen greatly. I can't recommend them enough!

I have been working with Alex for about a month and a half. He has been professional, organized, and strict. His techniques have improved my piano skills tremendously. My last piano teacher was not structured and as a result I did not learn anything from the lessons; she let me run the lessons and never taught me about music theory, hand techniques, or gave me homework. However, Alex gave me all of those things. He is patient and always wiling to share new information; he is not hesitant to answer to answer questions or critique your technique. If you're looking for someone who is serious, strict, and professional, I would strongly recommend Alex.

Alex is an amazing tutor. Working with him was a great experience. Alex identified and targeted my weaknesses in math; he reinforced whatever basics I was missing and then worked from there to polish my skills. He even worked on notes for me on his own time.

Alex was everything I needed in a tutor.

I have been communicating with Alex for about 8 months. First he was helping me with my Trigonometry class and now with Pre-Cal. I have zero issues with his performance. He is very professional and extremely knowledgeable about anything to do with Math. Keep in mind, he is good at both Math AND teaching/explaining it. I have every intention to use him for every Math class I have in my quest to obtain a degree in Com- Science. If he was living In Houston, he would probably be my wife's piano teacher.

I got tutored in Algebra for about a week and he was very accommodating of the time and when I needed more or when I needed less he was very flexible. He's an excellent tutor, he won't cut corners and will make you actually think and solve the work instead of hustling you along to the next one. If you're looking for a math tutor then I don't know that you really could find one better.

Alex has been a very helpful tutor. He is very patient and good at explaining confusing concepts. Would absolutely recommend!

Alex is a excellent instructor and comes highly recommended for dramatically improving my sons technique and well as keeping a young students interest positive and equipping him with the skills necessary to achieve his musical ambitions. His inhouse lessons are very accommodating and fees are very reasonable.
