Hello! I hold a Ph.D. and have 15+ years of teaching experience. I help students turn challenging math concepts into clear, manageable steps. I work with students from elementary through college and specialize in SAT Math preparation. My students have gone on to attend highly selective universities, including Ivy League schools.

My approach is patient, organized, and individualized. Rather than just showing students how to get the right answer, I help them understand why a method works, recognize patterns, avoid common mistakes, and solve problems independently. For School and SAT Math, I focus on both mathematical knowledge and practical skills: efficient problem solving, test-taking strategy, time management, and recognizing the question types that appear repeatedly on the exam.

One of my greatest strengths is explaining difficult ideas in language students can easily understand. I believe most students who struggle with math can succeed when concepts are presented clearly and patiently. Whether you need to catch up, maintain strong grades, prepare for an exam, or pursue an ambitious SAT score, my goal is encouraging, focused, results-oriented instruction tailored to your needs.

Approved Subjects

ACT Math

ACT Math

I hold a PhD and have more than 15 years of experience tutoring students in mathematics and standardized test preparation, with a particular specialty in college-entrance exams. I know the ACT Math section thoroughly, its emphasis on pre-algebra, elementary and intermediate algebra, coordinate and plane geometry, and trigonometry. And I help students master both the underlying concepts and the pacing strategies the timed format demands. My approach focuses on identifying each student's specific gaps, reinforcing the fundamentals those questions depend on, and building the confidence and speed needed to perform well under pressure. Whether a student is aiming to raise a subscore or reach the top of the scale, I tailor each session to their target and current level.
Algebra 1

Algebra 1

Does Algebra 1 ever feel overwhelming? I'm here to change that. I help students make sense of algebra by breaking tough concepts into clear, manageable steps you can actually follow. Together, we'll build a strong foundation in equations, inequalities, functions, and graphing. I'll always show you the "why" behind each step, not just the "how."
Algebra 2

Algebra 2

Algebra 2 is where things really start to build, and I'm here to make sure every new concept clicks. I help students work through the tougher material, from quadratics and polynomials to logarithms, rational functions, and beyond, by breaking each topic into clear, manageable steps. My approach is patient and structured, and I always focus on the reasoning behind the math so you understand not just how to solve a problem, but why it works. My goal is to help you strengthen your skills, close any gaps, and walk into every test feeling genuinely confident.
Elementary Math

Elementary Math

The early years of math set the tone for how a child feels about the subject for a long time, and I love helping young students build a foundation that's both strong and stress-free. I work patiently through the essentials — from counting, addition, and subtraction to multiplication, division, fractions, and word problems — breaking each idea into clear, manageable steps. Many kids come to me feeling like they're "just not a math person," so I focus on turning that around with plenty of encouragement and small wins along the way. My goal is to help your child strengthen their skills, fill in any gaps, and feel genuinely confident with numbers.
Geometry

Geometry

Geometry asks students to think in a whole new way: visually, logically, and step by step. And that's exactly where I help it click. Whether it's proofs, angles, triangles, circles, area and volume, or coordinate geometry, I break each topic into clear, manageable pieces and focus on the reasoning that ties them together. Proofs especially can feel intimidating at first, so I walk students through how to think their way from what they know to what they need to show. My approach is patient and structured, and my goal is to help you build both strong problem-solving skills and real confidence in the subject.
GRE

GRE

I hold a PhD and have more than 15 years of experience tutoring students across the full range of the GRE — Quantitative Reasoning, Verbal Reasoning, and Analytical Writing. Having earned an advanced graduate degree myself, I know firsthand what the exam demands and how to prepare for it strategically, from the algebra, arithmetic, and data-interpretation skills the quant section tests to the vocabulary, reading comprehension, and argument analysis at the heart of the verbal section. As an experienced academic writer, I am especially well-equipped to help students strengthen their Analytical Writing, teaching them to build clear, well-reasoned essays under timed conditions. I tailor each session to the student's target score and program goals, focusing on the specific areas where they can gain the most ground.
Korean

Korean

As a native Korean speaker, I bring both fluency and real cultural understanding to every lesson, not just how the language works, but how it's actually spoken and lived. I help students at every level, from learning Hangul and building first words to reading, writing, and holding natural conversations. My approach is patient and structured, and I focus on practical communication so you can use what you learn right away. Whether you're studying Korean for family, travel, work, or the love of the language, my goal is to help you speak with real confidence.
Linear Algebra

Linear Algebra

I hold a PhD and have more than 15 years of experience tutoring mathematics, including college-level and advanced coursework such as linear algebra. I help students work through the core topics of the subject — systems of linear equations, matrices and matrix operations, determinants, vector spaces and subspaces, linear transformations, eigenvalues and eigenvectors, and orthogonality — connecting the computational mechanics to the underlying concepts so the material actually makes sense. Because linear algebra is often a student's first encounter with abstract mathematical reasoning and proof, I focus on building the intuition behind the definitions and theorems rather than just memorizing procedures. I tailor each session to the student's course and level, whether they need help keeping up with lectures, preparing for exams, or deepening their conceptual understanding.
Prealgebra

Prealgebra

Prealgebra is the bridge between arithmetic and algebra, and getting it right sets students up for everything that follows. I help students build a solid grasp of the essentials: fractions, decimals, ratios, integers, and the first steps of working with variables and expressions. This is often where math starts to feel abstract for the first time, so I focus on the reasoning behind each idea to keep it from feeling confusing or intimidating. My approach is patient and structured, and my goal is to help students strengthen their skills and step into algebra with real confidence.
Precalculus

Precalculus

I hold a PhD and have more than 15 years of experience tutoring high school and college-prep mathematics, including precalculus. I help students master the full range of the course: functions and their graphs, polynomial and rational functions, exponential and logarithmic functions, trigonometry and the unit circle, sequences and series, and the analytic groundwork that prepares students for calculus. Because precalculus is where many students either build the foundation for calculus or start to fall behind, I focus on making sure the concepts are solid and the connections between topics are clear, not just memorized. I tailor each session to the student's course and pace, whether they need to keep up with class, prepare for exams, or get ready for calculus ahead.
SAT Math

SAT Math

SAT Math is my specialty, and I know exactly what it takes to move a score. Beyond the math itself, the SAT rewards strategy — recognizing question types, managing your time, and avoiding the traps the test loves to set. I coach you through all of it alongside the content. We'll build genuine mastery of the algebra 1–2, problem-solving, geometry, and data analysis the test covers, while sharpening the test-taking instincts that turn knowledge into points. My approach is patient, structured, and built around your target score, so you walk into test day knowing you're ready.
