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.

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!
