Award-Winning GMAT Tutors
serving Portland, OR

I attended law school at Vanderbilt University and I earned an MBA and a Ph.D. in Finance (Statistics minor) from the University of Iowa. I served for over 10+ years as a finance professor, teaching assistant, and tutor at 4 Top-40 public universities, during which time I received numerous awards for exemplary teaching. I qualified for MENSA by scoring in the 99.9th percentile on standardized tests for graduate schools: LSAT, 173 (6.0+ AWA) and GMAT, 760. I use a student-centered approach and I personalize educational plans to balance student needs based on learning styles, motivations, and interests. I have experience fostering one-on-one learning in a variety of environments, including online platforms. I guide students in identifying resources to improve their ability to succeed and monitor their progress while providing ongoing feedback. I will help you thrive in your mathematics, probability/statistics, and business courses or in your preparation for standardized tests.

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

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.

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 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".

While the focus of my career has been digital marketing, learning and teaching others has always been a pillar of my core values. I was a TA for a Rice University program and have been doing GMAT and SAT prep tutoring through Varsity Tutors off and on since 2020

Education is not one-size-fits-all. Every student deserves a stimulating environment that encourages intellectual risk-taking. As a facilitator, I guide students step-by-step to overcome obstacles, master difficult material, and unlock their full potential. My academic background reflects deep analytical versatility: I graduated from Tulane University with a triple major in Mechanical Engineering, Mathematics, and Philosophy. This rigorous foundation allows me to expertly tutor high-stakes exams. My passion for teaching began early tutoring peers in high school and teaching a class in college. Whether you are aiming to ace the quantitative and verbal sections for the GRE or GMAT, or tackling complex coursework in math or engineering, I provide the strategic framework you need. Let's work together to crush your target scores!
