Hey all! I'm offering discounted coaching since I just started again in May and I'm building up a client base again. I was an extremely active coach back in 2022 on Leland and several other platforms before I started at McKinsey and had to pause due to contractual obligations--feel free to check my reviews on Leland. I have extensive experience coaching across all aspects of MBA admissions: 1. I have helped 30+ students get into top MBA programs, including HBS, Stanford GSB, Wharton, etc. I also have experience helping several students get into top executive or non-traditional programs (Stanford MSx, Wharton EMBA, etc.). 2. I am a former professional writer, and I have helped almost all of my students brainstorm, recraft, tune, and edit their essays. This is primarily what I help with for MBA applications. 3. I spent years tutoring standardized tests (GRE, GMAT, SAT). While I no longer offer tutoring services, I can help you develop a study plan and tackle weak points. 4. I am a professional resume reviewer for both MBA admissions and consulting applications. 5. Additionally, I was part if the Student Admissions Program for the Wharton MBA program

About John
Just rejoined the coaching world after 3 years as a consultant at McKinsey! Offering discounted services for several weeks as I build up my student base again. I offer 3 primary services: 1. McKinsey/MBB specialist offering case interview prep (coached 50+ students to MBB offers); ALSO full preparation on everything from resume/networking to behavioral 2. MBA resume, essay, and interview coaching/review 3. GRE/SAT tutor with years of tutoring experience (NO LONGER OFFERED!) But I'm always happy to cater to anything you need help with! I love teaching and dreamt of being a teacher when I was younger, but unfortunately teachers are under-appreciated and underpaid in the US, so I went a different route. After quitting McKinsey, I declined several jobs to focus full-time on coaching. Feel free to message me with any questions, and I look forward to helping you land your dream job or MBA/graduate school offer! As a Wharton MBA student, I was extremely active in the Wharton Consulting Club and coached over 30 students to consulting offers. I'm also a former writer and psychology researcher, so I know exactly how to deliver and crush behavioral interviews, especially McKinsey's PEI. Since Wharton, I have also tutored an additional 50+ students in all aspects of consulting. I'm known for my rigorous/methodical casing approach and feedback and my devotion to my students (check my reviews on here!). During and before business school, I also helped students with MBA admissions, and I served in the Student Admissions Program while at Wharton. Additionally, I tutored the SAT and GRE, receiving a 170/170 quant, 169/170 verbal, and 5.5/6.0 analytical writing.
