Consultant Bio

My name is Greg Guglielmo and I am the Founder of Avanti Prep, a boutique MBA admissions consulting firm. I pride myself on offering an unmatched level of personal commitment, care, and attention to detail to clients, along with expertise across MBA admissions, coaching, storytelling, writing, and messaging.

I realize that may sound a bit like everyone on here, but I genuinely believe that my clients’ experiences and results tell a differentiated story. I invest completely in those who place their trust in me, and I deliver a unique degree of time, depth, and quality per engagement. So please keep reading and check out my reviews!

As far as background is concerned, I earned my MBA from UC Berkeley’s Haas School of Business, where I served on Haas’s eight-person student admissions team, conducted interviews, received a Haas Leadership Scholarship, and graduated with honors. I completed my undergraduate degree at Georgetown University.

Prior to founding Avanti Prep, I worked with applicants at Critical Square, another very successful boutique admissions consulting firm. Professionally, I’ve also worked for a leading private equity firm in San Francisco and was a Vice President at J.P. Morgan in New York, managing client relationships in the firm’s Asset Management business.

My written work has been published in leading media outlets, including ESPN and Nate Silver’s FiveThirtyEight (ABC News), and covered by The New York Times and The Washington Post, among others. Those writing and storytelling skills come in very handy when we’re in the (exciting) throes of story development and essay reviews!

Company Information

References to “quality” and “commitment” are easy to make in a bio like this, but they don’t mean much when they’re just words on a page. With that in mind, I strongly encourage you to read through my client testimonials (on my website, on GMAT Club, and down below) in order to understand what “quality” and “commitment” have meant to the applicants I’ve worked with.

In doing so, you might notice a few instances in which I worked with clients who had previously (unsuccessfully) worked with other consulting firms, striking out across schools before earning multiple admits and significant scholarships when we worked together in the next round or year (with the same stats and on the same or similar schools). I believe these case studies are the most telling with respect to the differentiated “quality” and “commitment” that I keep mentioning.

I hope we can meet, so please sign up for a Free Consultation via the link below!

Menu of Services and Associated Costs

I offer Packages (two tiers), Hourly Services, and à-la-carte Interview Prep. The Comprehensive Package spans every element of the application process. Hourly Services can be flexibly applied in any quantity or manner that you’d like.
My Interview Prep offering includes a school-specific mock interview and question-by-question coaching-and-feedback session, all over 2.5 hours – which is a good 90 minutes longer than the typical Interview Prep session you’ll find elsewhere!

  • Great help with interview prep and scholarship negotiation - a T10 and T15 admit with 100k in scholarships!
    2 days ago
    My background: Indian male, 30 years old, first-time applicant Undergrad: Engineering from an IIT with a decent GPA Postgrad: PGDM in Marketing and Communications from a Top 20 Indian school 5.5 years of work experience in advertising, branding, and product marketing roles GMAT: 750 When I decided to apply to business schools, my profile had quite a few obstacles that usually end up crushing most applicants’ dreams - a highly competitive demographic pool, age, no blue-chip employers on the resume, lot of job switches, and what some schools would consider a second MBA situation as well. Still, I knew that this was my ‘one and done’ shot at business schools, and so, I decided to give it my everything. I targeted one M7, three top 10, and one top 15 school ...

  • HBS / GSB Admit
    10 months ago
    I got an hourly preparation service for mock-up interview with Greg and found it very useful for my upcoming interview with HSB and GSB. The good things were: 1) very close to the real experience the type of questions Greg asked and a similar pace to the real interview; 2) thorough feedback and detailed analysis of the performance with comments on both verbal and emotional performance, as well as specific wording and stylistic element; 3) willingness to spend the time to cover everything I had concern with. I would mention Greg's balance of friendliness and professionalism, which created the perfect atmosphere for my mock-up interview.

  • Personal, Detailed Attention From Greg Got Me Into Great Schools!
    10 months ago
    Short summary first if you don’t want to read the whole thing: Thanks to Greg’s help, I was accepted to the Kellogg 1Y program, INSEAD, IMD, and USC, and I am convinced that I would not have been accepted had I not worked with Greg. Between the four schools, I received over $175,000 in scholarships. Since Greg is a small shop, he takes the time to get to know you personally and can really help you discover your voice. I consider myself a very compelling and articulate writer, but I was astonished at how much my essays improved after working with Greg. I would highly recommend working with Greg. Longer version for those interested: Age: 31 Sex: Male Nationality: American (Texas), white GMAT: 770 Schools applied: Harvard, Wharton, Kellogg 1Y, USC, INSEAD, ...

  • Over The Moon: 50% Scholarship To A Top 10 Program As An Indian Male)
    10 months ago
    Background Engaging a (sub-par) consultant during the last admissions cycle had already been a bitter experience that I primarily made due to the seemingly beneficial geographical proximity (they were based in the same city as me) and undeniably 'low-cost' services (be sure to verify advertised claims). Already on the other side of 30, I felt that this time around was really going to be my last real chance at gaining admission to a Top MBA program and I didn't want to leave any stone unturned. Here's some brief background: -Indian Male -US Undergrad + First Masters (Top 30 School) -750+ GMAT -9 years of work-ex -Re-applicant in R1 2018 (from R2 in the previous cycle) As an Indian male engineer with nine years of experience when I would start the MBA program, ...

  • 100% + 80% Scholarships To Two M7 Schools - Forever Indebted!
    10 months ago
    I couldn't be more thankful to Greg Guglielmo for helping me realize my goal. I engaged a very well-known admissions consulting firm for my round 1 applications. I was rejected from three M7 schools and received a waitlist invitation to a top 20 school. My objective metrics were reasonably strong (3.5 years' work at top tier law firm, 770 GMAT, strong extra-curricular involvement). While I felt my previous consultant did provide some useful pointers, I felt that perhaps his reviews were rushed and quite a high level. He did not drill down into the content of my essays or provide meaningful suggestions, and I did not feel I put my best foot forward. I dusted myself off and re-applied in round 2, this time to a further ...

  • Accepted Into Wharton
    10 months ago
    Choosing a Consultant: I had a pretty traditional & solid background when I applied, but really needed help with telling my story. I had spent a lot of time preparing for the GMAT and not a lot of time researching, so I felt a bit rushed applying to 5 programs in Round 2. I was looking for someone who was experienced with the MBA process to help me brainstorm story ideas, solidify my goals, and improve my essays. I had a few meetings with a few MBA consultants from larger firms but ultimately decided to go with Greg due to the thoughtfulness of his initial profile assessment. Working with Greg: I began with 10 hours and added a couple more hours later on. From the get-go, I felt like Greg ...

  • Accepted To Wharton & Columbia With $100k In Scholarships!
    10 months ago
    As a reapplicant who worked with a different consultant last year and did not receive interviews invites, I was anxious about applying this year and hesitant to work with a consultant. I can say with great confidence that this year’s success is completely a result of my work with Greg and his unique, personalized and brilliant approach to crafting my application. With a 740 GMAT, 3.85 GPA, 5 years of work experience at a big tech company, and career goals in brand management and entrepreneurship, there were no glaring red flags about my previous application. I felt lost when it came to improving my application, and apprehensive about my odds this year. I initially set up a free consultation with Greg, which went probably two times longer ...

  • Above & Beyond Doesn't Do Greg Justice...
    10 months ago
    When I started searching for MBA counselors, many started to sound similar - either promising to move mountains or being pessimistic on my candidacy. As a white American male in Finance from New York, slightly older than the average candidate with a 700 GMAT score and 3.3 GPA, I was realistic about my candidacy but optimistic with strong essays and direction I could succeed in the process. From Day 1, Greg broke this mold and working with him was by far the best decision I have made throughout the admissions process. Even before engaging, Greg offered to do a quick read through of a draft essay I wrote for a school, offering complimentary comments as part of his free consultation. He was frank about my odds ...

Georgetown McDonough- Accepted with 20K Scholarship 3. Kellogg- Dinged after Interview I was looking for a comprehensive service that would help me prepare my MBA application. I researched many consultants that would be cheaper as well as effective. Finally based on my friend's suggestion and talking to fellow mods, I decided to reach out to Greg. I was applying in R2 but started my application very late (after Christmas) Greg and I discussed my profile, goals and target schools. We initially started with my resume. I was in the assumption that my resume was good enough. But ...

  • From Despondence To Delight – Greg Helped Me Achieve My DREAM
    10 months ago
    Hiring an admissions consultant is never an easy task – especially with the plethora of options in the market and the significant cost involved. I approached Greg when I seemed to have lost direction regarding my MBA process and he turned out to be my best investment till date. My first attempt at GMAT landed me a disappointing 640 followed by a second attempt a month later which got me 700. I was confused and doubted my chances to land a good school with that score. Greg was warm and friendly and offered to hear my story over the first free consultation. Although only the first consultation is usually free, Greg voluntarily spent another session with me just to understand my background and what factors mattered ...

  • Indian IT Male: Full Scholarship To Top ~40 U.S. Program
    10 months ago
    It has been amazing working with Greg from Avanti Prep. The quality of service I received and the results that I ended up with were way above my expectations. I worked with Greg on an hourly basis for my resume, essays, and interview prep and received a full scholarship to a top ~40 U.S. program. I am an Indian IT Male with a low GPA and ~680 GMAT. Greg helped me bring out positives in my profile and highlight them in the best possible way. He was kind enough to offer me a free hour of service to finish the process for one essay we were working on. In the beginning, I had some issues with the payment, but Greg was kind enough to start working ...
