Hi, I’m Alejandro. I hold a Master’s degree in Chemical Engineering and have over ten years of experience tutoring students in math, physics, chemistry, and test preparation.

Hi, I’m Alejandro. I hold a Master’s degree in Chemical Engineering and have over ten years of experience tutoring students in math, physics, chemistry, and test preparation. Throughout my academic and professional training, I developed a strong appreciation for instructors who could make complex material clear and approachable, and that philosophy strongly shapes how I tutor today. I work primarily with AP-level high school students and college students in rigorous STEM courses, including calculus, differential equations, thermodynamics, college physics, and general chemistry, as well as SAT Math.

Most of my tutoring experience has been one-on-one, which has allowed me to adapt my teaching style to a wide range of students and learning styles. I often work with students who feel overwhelmed by fast-paced lectures or who struggle to connect formulas to underlying concepts. In my sessions, I focus on building understanding step by step, explaining the reasoning behind problem-solving methods, and helping students develop strategies they can apply independently on homework, quizzes, and exams. I emphasize clarity, structure, and patience, especially for students who feel anxious or lack confidence in math or science.

My goal as a tutor is to help students feel more confident, capable, and in control of their coursework. Whether a student is preparing for the SAT, taking on AP-level classes, or navigating challenging college STEM courses, I tailor each session to their goals and academic needs. I encourage students to reach out with questions and would be happy to discuss how I can support their learning.

Thermodynamics

I hold a B.S. and M.S. in Chemical Engineering and have tutored university-level Thermodynamics for 7+ years. I help ChemE/ME/Physics students master the first and second laws, state properties & EOS (ideal/real gases, compressibility), entropy/enthalpy, phase equilibria, and power/refrigeration cycles (Rankine, Brayton). My sessions are step-by-step: we derive key relations, read property/steam tables confidently, and then drill exam-style problems until the method sticks.

Very professional and knowledgeable tutor.

Alejandro was very knowledgeable and professional and was quickly able to assess my 14 year old son’s mathematical level and needs. My son is shy and doesn’t easily warm up to people, but Alejandro made learning fun, easy, and approachable. So happy we found him! I would 10/10 recommend him for all your SAT math needs.

Fantastic Tutor!!

Alejandro prepared the material beforehand and explained the thermodynamics questions very well!! He answered all of my questions and was really kind. I am very insecure about my learning style and he was super thoughtful and never made me feel stupid. Great person and great tutor!

Frances, 10 lessons with Alejandro

Super adaptable to tailor teaching style to fit your style!

Alejandro is a wonderful tutor who is very knowledgeable about pre-algebra. My son looks forward to each session and talks very highly of Alejandro. I highly recommend him!

Amal, 9 lessons with Alejandro

Patient helpful tutor

Alejandro was an awesome tutor. He looked over the assignment I needed help with well before starting our lesson to be sure he knew how to properly explain it to me. He was very patient and helpful with explaining the topics that I was struggling with. I would certainly recommend Alejandro for anybody looking for help with physics.

Alejandro Tutoring

Alejandro was very knowledgeable and prepared for the lesson I thought he did an excellent job. If I know of any other student I would be glad to recommend him.

Renie, 1 lesson with Alejandro

Knowledgeable and helpful tutor.

We worked on forces, he was able to help me understand the 4 lessons we were supposed to learn over 2 weeks in just 2 hours!! Would recommend him for AP Physics 1 tutoring.
