Meet Dr. Stuart Donnelly — Oxford Ph.D.
Founder of Tutors of Oxford, published author, and one of the most experienced private tutors in the United States — dedicated to helping students reach their full academic potential since 2004.
A World-Class Educator Committed to Your Success
Dr. Stuart Donnelly holds a Ph.D. from the University of Oxford, one of the world's most selective academic institutions. He earned his doctorate at the age of 25, conducting pioneering research in computational fluid dynamics under the supervision of Professor W.K. Morton, with funding from a full Science and Engineering Research Council scholarship and multiple research grants from Rolls Royce.
Stuart also holds an Honors degree in Mathematics and Physics, providing him with the rare depth of scientific knowledge and analytical rigor that makes him exceptionally effective across every standardized test he teaches.
In 2004, Dr. Donnelly founded Tutors of Oxford NYC in Manhattan, offering premium one-on-one tutoring for students preparing for the SAT, ACT, GRE, GMAT, MCAT, SHSAT, SSAT, ISEE, AP exams, GED, and beyond. His reputation for delivering measurable score improvements quickly established Tutors of Oxford as the city's most trusted private tutoring service. Today, Stuart serves students in New York City, San Diego, and worldwide through online sessions.
Over the past two decades, Dr. Donnelly has guided hundreds of students to acceptance at the world's most competitive institutions — including Harvard, Yale, Stanford, Columbia, Oxford, Cambridge, NYU Stern, Georgetown, Cornell, and many more. Prior to founding Tutors of Oxford, Stuart lectured at George Washington University and taught at the French International School in Hong Kong, one of the territory's most prestigious private institutions.
