Our Company

Twainstein was conceived as a one-stop shop to help graduate school applicants gain admission to their dream schools by walking them through every phase of the 16-week process, from GMAT/GRE preparation to school selection to fine-tuning essays and proper interview preparation.

Our Name

Twainstein Logo

Twainstein borrows its name from two of the most well known scholars of the 19th and 20th centuries: Twain and Einstein. One, the brilliant writer, the other, the preeminent scientist/mathematician. Once upon a time, top business/graduate schools sought to create their entering class from Twain’s and Einstein’s; that is, they believed that a diverse class of poets and quants (Business School parlance for writers and math-heads) would complement the team-oriented atmosphere prevalent in most top business and grad schools. Today, Top 25 programs are looking for candidates who possess both. Any weakness in one area can spell doom for an applicant. Twainstein was created to bridge the gap between poets and quants so that all of our student’s GMAT/GRE scores are well-balanced and their applications complete.

Application Consulting

What cardinal sins do most personal statements commit that seals their fate in the eyes of admissions committees? What could have been removed/added/revised or reworded that would turn an otherwise “rejected” or “waitlisted” response to an outright ACCEPTED? What words or phrases were used in describing past job descriptions or leadership accolades that will create an incongruity in the “line” of your story, forever tarnishing an otherwise stellar package? These landmines take a trained eye to suss out, and yet any one of them could easily offset a sterling GMAT/GRE score and derail your chances for admission.

Founder Avi Lidgi

Avi Lidgi founded Twainstein based on the well-documented Business School admissions principle that a successful applicant should be part poet, part analyst. This is what makes Business School so unique. Whereas most graduate programs are seeking either quantitative geniuses (engineering, medicine, accounting) or amateur Shakespeare’s (Art History, Law, Advertising, Psychology) Business Schools are looking for mastery in both. Part Einstein, part Twain, a Top 25 B-School applicant ought to shine in both major areas. Having spent five years in mortgage banking and six as a staff writer for the Los Angeles Times and Jewish Journal, Avi combined both of these skills to craft applications that earned him admission to the top Business Schools in the country. A graduate of UC Berkeley’s Haas School of Business, Avi founded Twainstein with the philosophy that every person can ace the GMAT or GRE, regardless of natural ability. It is a standardized test that can be taught (and learned), and Avi did so for four years as Master Instructor and Content Developer at one of the leading test prep companies in the country. There, he secured hundreds of admissions into top graduate schools for students whose lone weak area was the GMAT or GRE. Also, as a professional writer who has seen the ins-and-out of the Graduate School admissions process firsthand, he takes a scalpel to every personal statement that comes across his desk.
