P&Q Consultant Reviews

  • Review of John Sisk
    2 weeks ago
    "I was extremely happy working with John Sisk. I purchased 4 hours and used all of that time on application/essay review. He always responded quickly to my emails and questions. He was very honest and always provided constructive criticism which was important to me. He helped me nail down to the specifics in the essays which made them unique to me, which was key. He helped me see things that I was not always able to see. It was not an easy process, but John helped me through every step of the way. I felt very supported by him. Overall, I greatly enjoyed my experience with John and got into my top choice - a top 10 MBA program - because of him."

  • Excellent Experience with John
    4 weeks ago
    "I approached the MBA application process with a lot of confidence and focused most of my efforts on GMAT prep. It wasn’t until I actually got into the application process that I realized I needed guidance. I completed the free consultation at MBA Mission and realized that I didn’t know what I didn’t know. I purchased five hours of time with John and we began working on four school applications but it wasn’t until I began writing these essays that I really figured out what I wanted to do post-MBA. This provided my essays with direction and purpose. Without John’s coaching, my essays were pretty vanilla. Now, whenever I write ANYTHING, I envision John’s comment bubbles popping up, telling me “I need more YOU.” John ...Read the full review.

  • Five Stars for John!
    1 month ago
    "My message is simple: John was a major contributor to my recent acceptance to a top 10 MBA program. A lot of candidates have the stories and experiences to be competitive, but sculpting those stories into concise personal statements and essays that directly respond to the criteria of various admissions committees is an art – one that John has mastered. I engaged John on an hourly basis (purchased 5 hours through mbaMission). John was referred to me by a colleague who was admitted to a top 10 MBA program and credited John for his success. I had planned to apply to Booth and Kellogg. John initially sent me a brainstorming document with questions to help generate ideas for essays, short answers, and interview prep. We ...Read the full review.

  • mbaMission- John Sisk was incredibly helpful
    8 months ago
    "I chose John as my admissions consultant because I read that he liked storytelling and would help me tell my story to the Admissions Committee convincingly and authentically. He absolutely delivered. John and I went talked through my approach to the essays, and he guided me to craft my experiences in a structured way that would allow the Admissions Committee to find what they were looking for. We went back and forth on many drafts, and John pushed me to a winning draft of one of my Wharton essays. When John went on paternity leave, he ensured that I was in good hands to finish off the Wharton application (which eventually gained me admission)."

  • mbaMission - John Sisk - Highly Recommend!
    9 months ago
    "After burying myself under a pile of B-School essays, application materials and interview questions I realized I needed help and that came in the form of John Sisk at mbaMission. In our initial consultation session, he explained to me that applying to B-School is a marathon, not a sprint, and he was going to be there each and every mile along the way. The “Start-to-Finish” package was the right one for me as I was applying to six schools and had no idea how to even begin. John stepped right in to give me guidance on school selection and got my wheels turning on how to conceptualize my “story” for the various B-School essays. Over the next few months thoughts turned into well-articulated essays alongside ...Read the full review.

  • Helped me off the Stanford GSB Waitlist!
    9 months ago
    "John was a pleasure to work with and helped me manage an incredibly stressful waitlist process. After completing applications without an admissions consultant I found myself waitlisted (after interview) at Stanford GSB, MIT Sloan, and Wharton. John provided a logical and informed process to address my scenario and successfully navigate the waitlist. Even though the schools publically posted that they didn't need additional information, John helped me find ways to positively communicate to them and tip the needle in my favor. I found him to be responsive, and he always provided value added advice. My only regret is not hiring John as my admissions consultant earlier so I could have avoided the waitlist process in the first place! I can honestly say that without John's ...Read the full review.

  • Great Experience, Admitted to Top Choices!

    "I had a great experience working with John Sisk from mbaMission on my essays, resume and short answers. It was great to have a third party who really knows what he is doing and has no bias towards my writing/content. With his support, I was accepted into my top two schools (HBS and Columbia). I would highly recommend working with him. (1) John pushed me. Each time that I thought I’d nailed it, he’d reply with insightful feedback, always asking why….why did I want to do X in my career, why does Y motivate me...He challenged me, pushing me to take each aspect of my essays to the next level, really examining my motivations and how they play into my overall story. He is an ...Read the full review.

  • Great Experience, Great Results with John Sisk
    10 months ago
    "I had a wonderful experience working with John Sisk from mbaMission. I knew John was committed from our very first conversation, a free, 30-minute phone consultation. He asked detailed questions about my previous experiences and future goals, and based on what he heard, encouraged me to take a quantitative course prior to applying to bolster my quantitative profile. I ended up taking an Accounting course through UCLA Extension (one of several online options John provided immediately following our phone call); I do believe this made a positive difference in my application process, and I credit that entirely to John. As I began to write my essays, John was there every step of the way; he provided timely, detailed, and thoughtful feedback and also made himself ...Read the full review.

  • Great Experience with John Sisk
    10 months ago
    "John was incredible in guiding me through all aspects of the admissions process. I had just taken the GMAT for the 2nd time when I first talked with John towards the end of October and was fairly happy with my score but unsure of the best way to move forward in the process. John and I worked together on our game plan from there, and because I was adamant about going to business school in Fall 2016 we decided to move on from the GMAT (although my score could've used a little bit of a boost) and start focusing on the applications instead. He was instrumental in helping me choose which target schools to apply to and I appreciated how up-front and honest he was ...Read the full review.

  • Admitted to Top Choice

    "I would highly recommend working with John Sisk from mbaMission. His experience in journalism and his degree from a top business school give him a unique perspective as an admissions consultant. Entering the admissions process, I had a strong GMAT score and strong enough GPA to get into a top school, but I needed help rounding out my story. That is where Johnny was so helpful. After our free 30-minute consultation, I already had a great idea of how I wanted to put my story together, and over many iterations that story came to life with John’s help. I hesitated in spending the money to hire a consultant, but I found that I got great value from John using the hour-by-hour option. Having been accepted ...Read the full review.
