Manhattan GMAT

Chris Ryan

Chris Ryan

Manhattan GMAT
GMAT Instructor
GMAT Score: 790

Chris earned his teaching stripes the hard way -- in the classrooms of America’s high schools. A five-year physics and chemistry teacher and a veteran of Teach For America, Chris has been winning rave reviews for his work at Manhattan GMAT.


The bearer of a 790 official GMAT score, Chris has no shortage of teaching chops. In addition to blowing up high-school laboratories, Chris developed and taught a summer program on complexity theory, attracting a critical mass of other geeks (his undergrad degree in physics from Harvard gives him geek cred).


Having run out of explosives, Chris returned to school and earned his M.B.A. from the Fuqua School of Business (Duke), graduating in the top 10% of his class. While at Fuqua, Chris was the head teaching assistant in core Statistics and Finance courses. He also won both the Asa T. Spaulding Award for Leadership and the Distinguished Service Award for his contributions to Fuqua. Subsequently Chris worked for two years as an associate in McKinsey’s New York office.


Currently, as Director of Product and Instructor Development, Chris is involved in hiring, training and overseeing Manhattan GMAT instructors throughout the country. He also manages the creation and revision of content for our curriculum and other student offerings.


Outside of Manhattan GMAT, Chris pursues interests in the independent film world. He is an executive producer on Sólo Dios Sabe (Only God Knows), a Mexican-Brazilian feature film starring Diego Luna and Alice Braga that competed at the 2006 Sundance Film Festival. Chris is also co-adapting a novel into a screenplay.



Ron Purewal

Ron Purewal

Manhattan GMAT
GMAT Instructor
GMAT Score: 800

Ron Purewal has always been enthralled by standardized tests. In his elementary-school days, he never liked state-sponsored aptitude testing, because it always ended too soon; even today, he can be found loitering in the Study Aids section of Barnes & Noble, perusing everything from the curricula of second-language English proficiency tests to the weird dice that populate spatial reasoning exams.


He is an inveterate strategist, approaching every quandary in life - whether it be the GMAT, a sequence of Tetris pieces, or a decision about when to go to sleep or which lane is best in a traffic jam - with an absolute dedication to finding optimal solutions and explaining them, in detail, to whomever is fortunate (or unfortunate) enough to be listening. He is also an unconventional and flexible thinker, known for questioning dogma - whether that be the 'established' solution to a math problem or the 'acceptable' yet essentially arbitrary pairing of food items like cereal and milk - and for evaluating courses of action solely on their effectiveness. Ron brings these traits - an unflinching commitment to solving problems, and a remarkable diversity of approaches to finding those solutions - to Manhattan GMAT, where he is a natural choice to teach our 9-session course and private lessons.


Ron has taught students of all ages in almost every imaginable subject area, from AP calculus and physics to technical writing and human nutrition. He has taught standardized test prep for over a decade, and has written and edited major test-prep companies' curriculum materials. He will be teaching MGMAT's 9-session course in the San Francisco Bay Area, where he has lived since graduating from Stanford with honors degrees in mathematics and chemistry in '99.



Stacey Koprince

Stacy Koprince

Manhattan GMAT
GMAT Instructor
GMAT Score: 780

In addition to her teaching duties, Stacey runs her own consulting business in Montreal, specializing in comprehensive corporate strategy. As with all management consultants, she is an expert in any topic and on any problem a client cares to pose. Over the past decade, she has gotten quite good at telling other people what to do, including such clients as Intel, various European banks and AT&T (are there any consultants left who haven’t worked for AT&T?). She is also quite good at traveling to exotic locales on someone else’s dime (New Zealand is her favorite to date).


Before starting her fabulous consulting career, Stacey earned a biology degree from the University of Michigan, where she began her teaching career as the first undergraduate organic chemistry lab assistant. (She also worked as a university fundraiser, a barrista, an admin for a doctor’s office, a short-order cook, an emergency-room gopher... you’re probably beginning to get an idea why the consultant’s life is for her.)


Post-degree, she moved to Boston without a job and promptly began working for Another Test Prep Company when her rent was due. She helped that Other Company launch its medical board preparation programs and began her long and varied history with standardized test instruction. If you can think of the standardized test, she has probably taught it – including, of course, the GMAT, which she has been teaching for more than a decade (and on which she earned a score of 780). Her former students have gone on to such institutions as Columbia, Haas (Berkeley) and HBS. Stacey’s favorite thing about teaching is that moment when she sees the answering spark in her students’ eyes because they thoroughly comprehend a difficult concept.
