John Sisk

John Sisk

Senior Consultant

MBA from: Stern School of Business, New York University

Working style: Dedicated, direct, honest, practical, committed

What I love about my job: Helping people learn things about themselves that they didn’t know before, both professionally and personally, while teaching them how to write powerful, moving stories about themselves to make their future a reality.

John Sisk’s extensive background in journalism, advertising, and television, combined with his MBA from New York University’s Stern School of Business and a career-focused mind-set, have no doubt contributed to his having earned more than 75 five-star reviews on GMAT Club—positioning him as one of the leading consultants in the industry. With a BS in journalism from the Medill School at Northwestern University, John was one of The Huffington Post’s first Chicago-focused bloggers and spent five years in the media industry, starting as a page in the NBC Page Program. After a two-year stint with NBC, he worked as a producer on VH1’s Best Week Ever before transitioning to digital media buying at Starcom Worldwide, where he planned clients’ online marketing campaigns. While at Stern, where he specialized in finance, marketing, and TMT (technology, media, and telecom), John was a vice president of the Media Entertainment & Sports Association and contributed to the student newspaper The Stern Opportunity. And as a Graduate Fellow in Stern’s Office of Career Development, he reviewed students’ resumes and cover letters and conducted mock interviews, while working with recruiters from McKinsey & Company, J.P. Morgan, Boston Consulting Group, and Amazon, along with several other top investment banks, consulting firms, and technology companies.

People often say ‘I could not have done it without you,’ but in my case, I LITERALLY could not have done it without John. With John's continued support, patience, and enthusiasm, we were able to put together an application good enough for my dream school! If that doesn't win John the Rockstar Consultant of the Year award, I don't know what will!
