I have tutored students for the GMAT, GRE, SAT, ACT and LSAT for more than 15 years. I love it! As I tailor my instructions toward the unique needs of each student, my goal is to improve not only the student's performance but also the student's confidence as test day approaches.

I specialize in high-level GMAT diagnostic and execution coaching for stalled high-achievers. I don't just teach content; I identify the execution, timing, and decision-making patterns preventing score improvement and build customized strategies to break through plateaus under time pressure. After years of coaching GMAT students across a wide range of score levels, I've found that many advanced students underperform not because they lack ability, but because they approach questions inefficientlytreating each problem like a new puzzle instead of recognizing recurring execution patterns quickly and systematically. I earned my MBA from Georgetown University and worked as a former Sony engineer, bringing a data-driven and strategic mindset to every session. With 100+ five-star reviews, I've guided GMAT students to break barriersnot just raising scores, but shifting their confidence and thinking. As a result, many of my students have earned admission to elite MBA programs, including UCL
The GMAT tests two things most prep courses treat separately: quantitative problem-solving and verbal-analytical reasoning. Carl bridges both — his doctoral training at Yale sharpened his ability to dissect arguments and evaluate evidence, while his math tutoring background keeps him fluent in data sufficiency and integrated reasoning problems. He teaches students to read GMAT questions like an examiner writes them.
I enjoy helping students by explaining concepts in ways that make sense to them, by eliciting their feedback and tailoring my approach to their individual needs, and by conveying my enthusiasm for the learning process. It's great to see the light come on and to see their progress. I have an undergraduate degree in Politics from Princeton, a post-baccalaureate certificate in Quantitative Studies for Finance from Columbia, and an MBA from London Business School. I served as an officer in the Marine Corps and have worked in a number of academic and private-sector positions. I founded and am currently running an analytics-focused consulting practice.
I have always been driven to share my own passion for learning. While I was in high school, I tutored my peers after school. At college, I continued tutoring, but I also taught a class to middle-schoolers for a semester. Now, professionally, I teach seminars on Government and Politics. I went to Tulane University where I triple majored in Mechanical Engineering, Mathematics, and Philosophy. I tutor STEM topics, government, and test prep. My philosophy of education is that everyone is unique and must have a stimulating educational environment where they can grow. It is my desire to create this type of atmosphere where students can meet their full potential. I will provide a motivating environment where students are encouraged to take risks and strive for success. My teaching style is largely as a facilitator helping students overcome their obstacles.
I enjoy empowering students by making learning fun and believe that everyone has an "inner genius" that just takes the right technique to unlock. I bring a patient and friendly approach to teaching, specializing in the sciences, technology and math, and believe in teaching students to "learn for themselves".
I am an interdisciplinary educator with an Ed.M. from the Harvard Graduate School of Education and a B.A. from Dartmouth College. My background is primarily in integrated arts learning and museum education and I specialize in visual arts, history and art history, and object-based learning. In all subjects, I take a creative, inquiry-based and learner-centered approach, designing opportunities for each unique individual to meet their learning goals.
I'm not tutoring or buried in my textbooks, you will either find me rock climbing at the Triangle Rock Club, playing Ultimate Frisbee, working on my car, or enjoying the great outdoors (beaches, mountains, forests--you name it, I love it). On rainy weekends I enjoy tinkering with computers and old electronics, playing Pokemon, or picking at my guitar.
I am a recent graduate from a masters program in biostatistics at Columbia University. I received my Bachelor of Arts in biological sciences, with a focus in neurobiology at Northwestern University. In August, I will be starting a doctoral program in biostatistics at NYU. I was a teaching assistant at Columbia University in my department and also have tutored graduate students and undergraduates privately as well. My primary areas of tutoring are math and statistics coursework in addition to math sections on standardized tests such as the GRE and GMAT. I am very passionate about helping students feel more confident and excited about math. In my spare time, I enjoy running, playing piano, and spending time with friends and family.
I am a graduate of Wesleyan University, where I received my Bachelor of Arts in Sociology with High Honors. With eight years of experience working in education, I've tutored students in math, science, history, and English, as well as helped students prepare for standardized tests. I've guided adults towards passing the US Citizenship Exam and taught English in India, where I lived for six months. Whenever I work with a student I personalize the lessons to fit their particular learning style, since I know every student is unique and having the right fit can make all the difference in making learning fun and effective. My strengths are tutoring the social sciences and humanities, as well as making math and standardized tests approachable to students that normally don't like those subjects. In my spare time I like traveling, spending time in the outdoors (climbing & backpacking), meditation, and playing soccer. Next fall I will be beginning my PhD in Education at Harvard University.
I am proud to be a part of Varsity Tutors! I am originally from San Antonio, TX; I completed my undergraduate education at Rice University in Houston where I received a bachelor's degree in Biochemistry and Cell Biology. Currently, I am in my second year of medical school at Baylor College of Medicine.
I am a graduate of Washington University in St Louis, where I received my Bachelor of Arts in History with minors in Humanities and Anthropology. Since graduation, I have worked as a tutor, teacher, and director of tutors at a charter public middle school in Boston. During this time I also received my Masters in Mild to Moderate Disabilities from Simmons College. I have worked extensively with students with a range of abilities, including students with specific learning disabilities, emotional impairments, dyslexia, and ADHD. My teaching experience has given me a deep understanding of the knowledge and habits essential to academic success and has given me the opportunity to hone a variety of strategies that ensure students at each level can achieve their academic goals. While I tutor a broad range of subjects, my favorite ones are Reading, Elementary/Middle School Math, History, and Test Prep. In my experience, tutoring is the most rewarding when a student has that "aha!" moment and achieves a new level of understanding and confidence in his/her abilities. I am a firm believer in the transformative power of education, and I see my role to be that of a facilitator and coach who is there to help the student reach his/her goals through individualized support and rigorous practice. In my free time, I enjoy reading, running, practicing my Spanish, and discovering new music. I am also an avid traveler and just got back from a 3 month trip to South America. I look forward to the opportunity to work with you!

Frequently Asked Questions
Score improvement depends on your starting point and study commitment, but students typically see gains of 50-100 points with focused preparation. Many students improve their weakest sections significantly—for example, someone struggling with quantitative reasoning might boost that score by 80-120 points through targeted practice and strategy refinement. The key is identifying your specific weak areas early and working with a tutor who can address them systematically.
Your first session typically includes a diagnostic assessment to understand your current strengths and weaknesses across all sections—Quantitative, Verbal, Analytical Writing, and Integrated Reasoning. The tutor will discuss your target score, timeline, and any specific challenges you're facing, then create a personalized study plan tailored to your goals. This foundation helps ensure every subsequent session builds directly toward your score improvement.
The Quantitative section often poses the biggest challenge for test-takers, particularly questions involving data sufficiency and advanced algebra—many students haven't used these skills in years. The Verbal section trips up students who struggle with reading comprehension under time pressure or need to strengthen their grammar fundamentals. A personalized tutor can diagnose which sections are holding you back and use targeted strategies like timed practice drills and concept reviews to build confidence.
Timing is critical—the GMAT is an adaptive test with strict time limits (about 2 minutes per question), and poor pacing can tank your score even if you know the material. Many students rush through easy questions to save time for hard ones, or get stuck on difficult problems and run out of time entirely. A tutor can teach you strategic approaches like identifying question types quickly, knowing when to guess strategically, and building the stamina to maintain focus across all four sections.
Most students benefit from taking 4-6 full-length practice tests spaced throughout their preparation—this builds test-day stamina and helps identify remaining weak areas. The official GMAT practice tests are the most accurate predictor of your actual score, so prioritize those over third-party alternatives. Your tutor can help you analyze your practice test results to spot patterns in mistakes and adjust your study strategy accordingly.
Most students prepare for 2-4 months with consistent study, though your timeline depends on your starting score and target. If you're aiming for a top business school (700+), expect to invest more time than someone targeting a 650. Working with a tutor can compress your timeline by eliminating inefficient study habits and focusing your efforts on what actually moves the needle for your score.
Test anxiety often stems from unfamiliarity with the format and time pressure—taking full-length practice tests regularly desensitizes you to these stressors and builds confidence through repeated success. A tutor can also teach you mental strategies like breaking complex questions into smaller steps, managing negative self-talk, and maintaining focus when facing difficult material. Knowing you've thoroughly prepared and practiced under realistic conditions is the best antidote to test day nerves.
Look for tutors with strong GMAT scores themselves (typically 700+), proven experience teaching the test, and familiarity with the adaptive format and question types. They should be able to explain not just the correct answer, but why wrong answers are traps—and adjust their teaching style to match how you learn best. Varsity Tutors connects you with expert tutors who have the credentials and experience to guide you toward your score goal.
