“There’s no ‘I’ in TEAM.” From the boardroom to the playground, from the pros to youth sports, this phrase is repeated again and again. While the mantra may elicit a fair amount of snappy comebacks ("But there sure is an M-E" or "But there's a U in SUCK"), we understand its core message: you can't win going it alone.
As much as young Mario may have resented that phrase—I was destined to be a professional athlete, my jealous peers just didn't realize—I understand today how foundational teams have been in my life. From my parents who instilled in me a strong work ethic and the value of education, to my college football teammates who underscored the importance of determination and time management, all the way to my case teams at Bain who showed me the power of collaboration and asking for help, one thing is clear: teamwork makes the dream work. Unsurprisingly, some of my lowest lows have come from the absence of teams: when I’ve tried to go it alone, refused to ask for help, or not opened up to those around me. It’s because of the support of others and the undeniable power of teams that I stand where I stand today.
With this in mind, I strive always to be a teammate to others: to go the extra mile in a friendship, to bring fire and enthusiasm to coworkers during a tough week in the office, to lift up my GSB squad mates in a game of pickup basketball. I've made teamwork and mutual support a cornerstone of who I am. Whether it be my extreme extroversion, my fascination with gameplay, or my genuine love of my fellow man, teamwork makes me tick. I actively seek out scenarios where I can be a teammate for others in need. Recently, that’s taken the form of my role as a Youth Basketball Coach, and a Personal Leadership Coach at the GSB. Now, I'm excited to continue this trend at Leland, as we team up to tackle the world of MBA admissions.
An oft-cited African proverb states: “If you want to go fast, go alone; if you want to go far, go together." Let's conquer these apps, together.

Helping you get into your dream school is the name of the game, plain and simple. Together, we will define your application story, use your application "real estate" most effectively, supercharge your recommendation letters, and ace your interviews. My recent experience through the process, my command of decades of Bain's institutional knowledge on how to apply to business schools, and my genuine enthusiasm for teaming-up, grinding, and succeeding together, make me the perfect coach for the scrappy applicant. I have extensive experience in the world of coaching and mentoring. As a lifelong sports enthusiast, I've long understood the importance of a coach who's invested in your success. I've relished the opportunity to be this committed mentor as a volunteer with Big Brothers Big Sisters, a Youth Basketball Coach, and a Summer Camp Counselor. Recently, I served in the Arbuckle Leadership Fellows program at Stanford. Currently I am a management consultant at Bain. I'm a dual master's degree holder from Stanford's Business and Education schools. I attended undergrad at Wharton, graduating with dual concentrations in Finance and Operations. Afterward, I worked at Bain & Company, where I spent extensive time in our private equity practice, led the Penn undergraduate recruiting team, and spearheaded the Latinos at Bain (LATBA) employee onboarding experience. I briefly left Bain to serve as a strategic extern at the National Football League, in their Club Business Development group.
