GMAT Tutors, Events, and Resources

The only way to do well on the GMAT and the GRE is to understand the material and to know how to answer the questions. Cheats and guessing strategies don’t work, and you can’t “beat” or “outsmart” the tests. I am a Certified Teacher who has taught the material that appears on these tests in school. MY APPROACH IS TO TEACH YOU THE CONCEPTS AND SKILLS YOU NEED TO ANSWER THE TEST QUESTIONS CORRECTLY. I scored in the 99th percentile on the GMAT and the SAT, and I have a thorough understanding of the tests. I am a writer, with excellent language skills. As a Certified Teacher, I have 20-plus years’ experience as a teacher, tutor, test prep coach, and business trainer. I am a former teacher of high school math – exactly the math that appears on the tests – and of English grammar and writing. I am a trained and certified teacher. I have a Bachelor of Education degree and Adult Education training. I also have an MBA and have worked on Wall St as a Vice President at a major financial institution, as well as in several other business and management positions.

I graduated in three years from the University of Miami with a Bachelors degree in the fields of Environmental Science and Economics. After coaching over 100 students in academic and test preparation, working for a test prep company, and providing management and support for undergraduate students in the University of Miami Herbert Business School, I decided to pursue GMAT preparation. I am confidently able to solve the hardest questions given in the quant and verbal sections of the GMAT, and I am confident that I can help you on your journey. I also worked for a test prep company where I gained valuable skills and insights into guaranteeing score increases with all the students I worked with. I have a proven step by step system to raise your score. It starts with learning the key concepts that are tested and then applying these concepts in real test questions from tests. I am passionate, patient, and empathetic, and I believe that every student has their own academic talents that are revealed when provided the right environment and mentor.

The GMAT is a fascinating test compared to others I have coached for (SAT, MCAT, USMLE, etc) if for no other reason than because of its unique scoring and administration system. The GMAT is also differentiate from other professional school exams in that test takers are working professionals applying to business school in parallel with full-time work (as opposed to students with more flexible schedules) and the exam tests topics that most examinees have not directly used in years (think: geometry, multivariable algebra, etc). Each of these features add a dimension to the learning curve which can either make the exam especially challenging OR can be leveraged to accelerate score improvement relative to other examinees. When I coach GMAT clients, we focus on the HOW more than the what. Specifically: how to prepare for the test (what to do each day of prep) and how to take the test (what to do when at the computer on exam day). Focused review of specific content can also be useful on a case by case basis for topics that are particularly problematic for the client and also highly represented on the exam.

I bring over 14 years of experience teaching maths at the university level, combined with extensive expertise in GMAT preparation, particularly the new GMAT Focus Edition. As a Professor, I specialize in building deep quantitative reasoning skills — not just shortcuts, but real structural understanding that leads to consistent high performance. What differentiates me as a GMAT coach is my analytical, data-driven approach. I don’t believe in generic study plans. I diagnose performance patterns, identify conceptual gaps, timing inefficiencies, and decision-making errors, and then build a personalized strategy tailored to each student’s target score and timeline. I have worked with students helping them improve not only their Quant and Data Insight scores, but also their overall test-taking strategy, time management, and confidence under pressure. If you’re looking for structured thinking, clarity, and a strategic roadmap to maximize your GMAT score — I’m here to help you get there.
