Spanish

I am a native Spaniard with a perfect command of both the Spanish and English languages, having used both languages for over 25 years. I can give my students insights into the use of Spanish that few teachers can provide, including the origins of words, their cultural contexts, and a guide to the most proper use of each word and construction. Spanish is a universal language with the second largest number of native speakers, and a cultural heritage including the immortal Don Quixote (the second most published book worldwide after the Bible), Lope de Vega, Quevedo, Borges, Garcia Marquez, and many other universally recognized literary authors. Whether you need help learning basic or taking your Spanish to the next level or you need a translator with the knowledge and dedication requisite for your job, I would be happy to help you.

Precalculus,

Precalculus

Precalculus is a key subject in the High School curriculum which formalizes and extends many of the concepts in previous courses and adds new ones that will serve as a bridge to later courses. This makes Precalc a particularly challenging subject for many students, and at the same time it makes it a specially important one, as it lays the foundation for the more advanced concepts and procedures routinely used in Calculus. I have extensive experience tutoring PreCalculus to students of all levels, and my ability to make the concepts in the Precalculus curriculum understandable to any student by following different approaches is one of the reasons that sets me apart. I have been helping students succeed in Precalc for many years, let me help you as well!
SAT Math,

SAT Math

I have been helping students improve their SAT Mathematics scores for many years. SAT Math uses concepts that are not particularly challenging, but because students are likely to not have seen some of the specific types of problems in the SAT Math exam most are likely not to score up to their full potential. I will help you practice, reason, and fully understand all the types of problems you will be tested on in your SAT Mathematics exam so you can be confident that when exam day comes you will be prepared to do well.

Awesome, reliable and knowledgeable tutor

Ruben is probably one of the most involved tutor we've come across. He spends a lot of time with my son and really explains the material in an easy to understand way. My son has a very difficult time with Precalculus, but Ruben is really helping him. Ruben makes himself available and really puts the effort in. I don't think there's a better tutor!

Knowledgeable and accommodating tutor

Ruben did a great job tutoring my son. Ruben explained and did practice problems with my son in areas he needed help with in precalc. My son was able to do precalc problems with confidence because Ruben helped him understand the subject matter. I highly recommend him.

Sincere and great teacher who teaches the right way, not shortcuts

Ruben is a genuinely great teacher! He helped our kid with a major turnaround in his performance in AP Calculus. Ruben worked with our son to understand what he needs and then came up with a plan to achieve his goals and executed perfectly on it. I highly recommend Ruben if you are looking for someone who will help your kid understand, practice and learn the right way!
