I’m a dedicated STEM tutor with over 8 years of experience helping students master subjects like biology, chemistry, physics, and math. My academic journey began with a BA in Biochemistry from Columbia University, followed by an MSc in Biomedical Sciences from Mount Sinai. I am currently in medical school where I had the opportunity to serve as head TA.

My tutoring experience spans one-on-one and group settings, working with high school, college, and graduate students. I believe in tailoring my approach to meet each student’s unique needs. I focus on simplifying complex concepts and using real-world examples, helping students grasp challenging material. My goal is not just to complete assignments but to ensure students fully understand the underlying concepts, which leads to long-term success. I tutor in both English and Spanish, providing bilingual support for students who may feel more comfortable learning in their native language.

Patience and adaptability are at the core of my tutoring style. I’m committed to creating a supportive and engaging learning environment where students feel comfortable asking questions. Whether you're preparing for exams, need help with homework, or want to boost your confidence in STEM subjects, I’m here to guide you every step of the way. Let’s work together to help you reach your academic goals!
