PhD Math Tutor | Calculus, Algebra, Precalculus, & SAT Math

Grainne O.

Hi! I'm a math tutor who loves helping students unlock their potential in math. I break down complicated topics into simpler steps so students can understand the reasoning behind the math and feel more confident solving problems on their own.

I have a PhD in Atmospheric Science from Rutgers University and a bachelor's degree in Mathematics from Hofstra University, where I graduated summa cum laude. My education and research have involved extensive mathematics, including calculus, differential equations, statistics, and applied mathematics.

I have several years of teaching experience with students of different ages. At Mathnasium, I worked with K–12 students, helping them strengthen their math skills and understand challenging concepts. As a teaching assistant at Rutgers, I supported college students with quantitative coursework and graded assignments and exams. I have also worked as a high school substitute teacher and given presentations to high school and college students on careers in mathematics.

My tutoring style is patient, supportive, and tailored to each student. I work with students to identify where they're getting stuck, break concepts into manageable steps, and practice problems together until the material makes sense. I want students to feel comfortable asking questions and making mistakes as they learn. I can work directly from class materials, homework, and upcoming exams to focus on each student's needs.

I tutor Algebra I, Algebra II, Precalculus, Calculus I, and SAT Math. Whether you want to strengthen your foundations, prepare for a test, or better understand a challenging topic, I'm happy to help!
