Accepted To M7! Greg Is Fantastic!

REVIEWER IDENTITY VERIFIED by school email address [?]

As a reapplicant from an overrepresented demographic, I knew I needed to approach my MBA applications with a fresh perspective and a strong, differentiated narrative. Greg helped me think from first principles, challenging me to dig deeper into my experiences, goals, and motivations. His guidance was strategic and highly personalized—he didn’t offer generic advice, but instead took the time to truly understand my story and how best to present it. Greg went above and beyond, providing detailed, candid, and thoughtful feedback on every component of my application. Thanks to his expertise and diligence, I was ultimately accepted to multiple M7 schools. I couldn’t have asked for a better partner in the process.

Excellent Coach and Tireless Worker

REVIEWER IDENTITY VERIFIED by score report [?]

I started relatively late in the Round 2 cycle, engaging with Greg in late October, while working to raise my GMAT score (and dealing with a below avg undergrad GPA, albeit from a T5 public school).

Greg did a great job of breaking down the process, telling me what was (and wasn't) achievable, and distilling my key strengths and unique selling proposition for application essays. He was essential in helping me polish "Why MBA" into a concise story that I was able to use in networking with students/adcom, my essays, and ultimately interviews.

He went above and beyond throughout the process, helping me navigate idiosyncrasies that arose in various applications, and ended up providing ~10 additional hours over our budgeted 30 hours for free.

Ultimately, I received a significant ($$$) scholarship from a T15 school (which he helped me navigate off the waitlist), along with acceptances (with $$) to other T15s.

I could not have done this without Greg and firmly believe he provides the best value compared to others in the space.

Excellent experience with Greg from Avanti Prep

REVIEWER IDENTITY VERIFIED by post count [?]

I have watched Greg on multiple GMATClub videos and appreciated his openness in discussing various admissions-related questions, which led me to sign up for Avanti Prep's free consultation. We had an engaging conversation, and he was very kind to stay longer (70 minutes) during the first consultation, adding a second free consultation (75 minutes) to answer my long list of questions, given I was applying to reach schools with lower-than-average test scores.

I signed up for his hourly service to mainly work on my resume and one school essay, given my budget constraints. I thought I had a decent start on my resume, but Greg asked numerous questions to better understand my job responsibilities, allowing me to flesh out and highlight the most critical aspects. The final draft turned out to be perfectly polished. I enjoyed working with him, so I added additional hours to review my essays for an additional school at the very last minute (not something I am proud of), and he somehow managed to review them on 31 December, just before the R2 deadlines.

I believe the quality of my resume, essays and all the complementary information that Greg provided (recommender preparation material and interview prep guidance) was crucial in securing admission to a T10 school.

Overall, Greg is an excellent consultant - someone who is super polite, encouraging and truly invested in you throughout the process. I highly recommend Avanti Prep to everyone, especially to applicants who are on a tight budget and may be unsure whether a few hours of consulting can make a significant impact on their application package - it absolutely will!

I worked with Greg at Avanti Prep for my Round 2 MBA applications and couldn’t have asked for a better guide. I’m a software engineer from a top state school (3.7+ GPA, GMAT 750+), ORM, with a compelling side project but not a natural communicator. My biggest challenge was figuring out how to stand out and clearly “sell” my story. I found Greg via YouTube, and his transparent, approachable style immediately stood out. What followed was a true partnership: we tackled everything - recommendation letter strategy, essays, interview prep, resume polish, and a lot of last-minute, deadline-driven advice/support. Greg’s feedback came not just through comments in Google Docs or Word, but also over live Google Meet sessions and thoughtful emails, making every round of edits actionable, honest, and directly tailored to each school.

Greg’s real strength is helping you clarify your brand, voice, and story. He never let me settle for surface-level answers and was always pushing for more depth and clarity, no matter how many iterations it took. His school-specific insights were invaluable; every application felt customized rather than generic, and when it came time for interviews, he even researched my real interviewer to tailor the prep. His commitment showed in fast turnaround, transparent communication, and a genuine investment in my results. He treated my goals as his own.

Thanks to Greg’s guidance, I was admitted to both schools I applied to (Stanford GSB and Berkeley Haas) with a significant scholarship at one. If you want expert, honest, and deeply personalized support, I can’t recommend Greg and Avanti Prep enough. I went in thinking Haas was my best-case scenario and came out with Stanford too. Working with Greg truly made all the difference.

Best coach I’ve ever had—the difference in quality is clear

REVIEWER IDENTITY VERIFIED by score report [?]

I worked with a few different coaches at various points in my MBA application journey,
and Greg was without a doubt the best. Before working with Greg, I did not really
understand how there could be such a big pricing or quality difference between
coaches. After working with Greg, the difference in quality is clear.
You simply cannot compare the level of nuance, experience, and school-specific
expertise of someone (Greg) who has done this thousands of times for hundreds of
applicants to a coach who has only applied on their own, helped a few clients, or does
this on the side. It becomes evident as soon as you speak with him.
I am an applicant from South America who had targeted mostly T30 schools in
Round 1. Thanks to Greg’s guidance, I was admitted to Berkeley-Haas and even
waitlisted at Stanford in Round 2—a dream result and massive upgrades for me coming
out of Round 1. I truly believe I couldn’t have done it without him. (I am still on the
waitlist at Stanford, trying to increase my GRE score, and holding out hope!)
Beyond his professionalism and expertise, Greg brought a level of dedication that is
incredibly rare. He genuinely cares. You’re not just a client—you’re someone he’s fully
invested in. It felt like he owned the mission of getting me admitted. When I succeeded,
it felt like we succeeded. And had I not, I know he would’ve felt the pain just as strongly.
That level of emotional investment is rare and deeply motivating.
On top of that, Greg is unbelievably proactive. He was always a step ahead, sending
me exactly what I needed to do next—even things I didn’t know I should be doing to
maximize my chances. From little things like finding the right ways to engage with club
members to crafting a thoughtful post-interview thank-you email to so much more, he
knew it all and made sure I was on top of every detail.
Greg isn’t doing this on the side—he’s a true professional. Coaching is his craft, and it
shows in everything he does. He’s full-throttle, forward-thinking, and the most committed
coach I’ve encountered. If you're serious about getting into a top MBA program and
want someone who will coach you like your success is his own—work with Greg. Best
coach I’ve ever had. Hands down.​

Gifted Writer and Mentor

REVIEWER IDENTITY VERIFIED by school email address [?]

GRE Score of 319, top 30% in my class, and transitioning Naval Officer. I used Greg's hourly service for 20 hours of essay prep for three M7 schools. I was accepted at one and waitlisted at another. I was hesitant to have someone help craft my essays, but he knew how to guide and not take over my narrative. He took my disorganized thoughts across multiple drafts and showed me how I could amalgamate them into coherent themes. I felt confident that all my essays were my own original thoughts expressed in my unique voice. I plan to stay in touch with my new friend!

Accepted to M7 - Greg is a must use!

REVIEWER IDENTITY VERIFIED by school email address [?]

I came from Consulting industry and had a 3.82 GPA with 329 GRE. I needed help crafting my Personal Statements and supplemental essays.

I was accepted at multiple M7 and T15 programs with a scholarship ($$) and cannot recommend Greg more. Working with Greg was the smartest thing I did during my admissions process. He invested a ton of time and went above and beyond to help craft my stories and essays. The investment in his hourly services definitely paid off and was worth every penny.

The one application that I did not use Greg for was the only school that I was not accepted to - go figure.

Cannot Recommend Greg / Avanti Prep Enough!! Accepted to M7

REVIEWER IDENTITY VERIFIED by score report [?]

Product Avanti Prep Package

Consultant Greg Guglielmo

Background: Female, International, GMAT: 655, 2.5 years work experience at a boutique investment bank.

Greg was such a pleasure to work with and I wholeheartedly recommend Avanti Prep to anybody looking for career coaching or MBA consulting services. I started working with Greg on the Columbia Business School application 2 months before the R1 deadline and got accepted! Unlike larger consulting firms, Avanti Prep adds a personal touch and has exceptional service and dedication. Greg goes above and beyond and roots for your success. I've spoken to many current MBA students and most of them did not have the same experience with other consultants at other firms so I feel incredibly lucky to have found Avanti Prep!

Product Avanti Prep Package

Consultant Greg Guglielmo

Background
- White Male (US)
- GPA: Above a 3.5 from Top 20 Liberal Arts College
- GMAT: Above 700
- Previous Role: US Military Officer

When I initially considered applying to business school, I spoke with one of my friends, also a former US military officer, who had been accepted at LBS. He highly recommended that I work with Greg, who was the “best in the business.” I took my friend’s advice, and I am extremely grateful that I did. Greg helped me develop a narrative about my accomplishments and my unique strengths that differentiated me from other applicants. That is the most valuable aspect of having Greg as your consultant – he understands what resonates with admissions officers at individual schools, and he can help you structure your application to highlight your best attributes and show that you can add value to a specific MBA program.

Greg put forth a great amount of time and effort to learn my story: my GPA / educational background, my test scores, my work experience, my interests outside of work, and my past community outreach. He worked with me on several iterations of my resume to make sure it captured all of my relevant and unique experience. His mock interviews reflected the tone and style of each individual school, and he provided feedback that allowed me to craft insightful responses to potential interview questions. Greg’s efforts had an enormous positive impact on my applications, and the results reflect this.

Results: I applied to 6 schools, received interview invites at 5, was accepted at 4 (HBS, Booth, Ross, Darden), and withdrew 1 (LBS) after being interviewed. Greg’s effectiveness was demonstrable throughout the process, from start to finish. It is also worth noting that I received scholarships at 3 of the 4 schools to which I was accepted.

Dream outcome: dual admit GSB/HBS

REVIEWER IDENTITY VERIFIED by post count [?]

As a non-traditional background applying in R2, Greg had successfully elevated my profile for top business school, leading to dual admit to GSB and HBS + misc. offers and waitlist (most are M7)

Greg analysed my background and story diligently and provided very useful feedback to elevate my profile. He is also not afraid to be frank about his comment and approaches, which contributed the good chemistry between the both of us.

Greg is always looking to improve my whole profile, including essay, additional essay, interview answers, even in the smallest possible way to ensure there are no rocks left unturned.

although he has a proforma for certain things, he remained very flexible and would patiently listen to my recommendation and incorporate them into the end product (Eg. essay). He is also not afraid to criticize my approach when needed, making him not just a great consultant, but also a tutor.

Overall, I would definitely recommend him to anyone who wants to aim high. But a reminder is that - be ready to put in the work to complement his hard work!
