Since we met, Ossama has been more than a mentor; he has been an unwavering champion of my growth. At Deloitte, he guided me through everything from community initiatives to high-stakes turnaround projects. Ossama was crucial during my transition to New York. From lunches to strategy sessions, he saw my potential and empowered me to exceed my limitations. His true superpower is the psychological safety he creates. This makes him invaluable for coaching. At difficult career crossroads, his 'big picture' thinking provided a new vantage point that shifted my perspective. He was instrumental in crafting my narrative and prepping me for interviews, transforming uncertainty into clear direction. For anyone seeking a down-to-earth champion who makes it safe to dream big and helps you execute even bigger, Ossama is the one.

Ossama provided comprehensive support throughout my consulting preparation process. His expertise in case study analysis strengthened my structured thinking, his guidance on resume refinement made my CV clearer and more compelling, and his interview preparation support contributed substantially to my professional development and acceptance.

Osama was incredibly supportive throughout my interview preparation process. He helped me analyze a complex case study, guided me through a structured consulting approach, and even supported me in developing a clear and compelling PowerPoint presentation prior to presenting it to the partner at one of the Big 4 companies. His ability to break down problems, challenge assumptions, and provide practical, actionable feedback made a real difference. The interview went very well, and his guidance played a key role in that outcome. I highly recommend Osama to anyone looking for thoughtful, hands-on consulting support and interview preparation.

Marie was my manager for my summer internship at ButcherBox in 2024, where I was the company's first Product Manager Intern. Marie was immensely helpful, and continues to be. For the internship, Marie planned out my summer to develop PM skills effectively, helped me to shift from an individual-contributor engineering mindset to product management, coached me on effective presentation strategy to company leadership, and helped me to navigate impostor syndrome in a role and industry that were both new to me. A year later (2025), Marie also coached me on my resume. I can now say with confidence that Marie's management and mentorship were valuable in progressing my career, as I have now landed my post-graduation dream role in product management for an environmentally sustainable company.

One of the most knowledgeable finance professionals I’ve had the pleasure of working with. Andrew’s insights and guidance have been instrumental in my career development. From banking to PE and public investing, Andrew’s got a broad and unique set of experiences to learn from. Can’t say enough good things.

Jay is amazing at supporting others and I have had the privilege of him steering me in the right direction on many occasion’s . His approach is like non other very honest, realistic and leaves a great impression on you. I can count many times that I have come to him for advice, and opinion and there has been times that he has provided guidance not even knowing. He is humble in his work while being impactful to those around him.

I’ve been incredibly fortunate to have Ossama as a mentor throughout the most pivotal stages of my career. From guiding me through a complex transition from the Middle East to the US, to providing thoughtful, candid advice on career decisions, he has consistently gone above and beyond. His support during my Wharton eMBA application was invaluable: he helped me shape my narrative and pushed me to articulate my true leadership story. He also played a critical role in preparing me for high-stakes interviews, meticulously reviewing my resume and helping me position my experience in a way that ultimately led to successful outcomes. What truly sets him apart is his genuine investment in the people he mentors: he combines strategic insight with deep empathy, and he challenges you to aim higher while giving you the confidence and tools to get there.

For more than 15 years, Ossama has been the mentor who shaped not just my career, but my entire professional identity. From my earliest days in industry to navigating the complexities of consulting, he has been the steady voice pushing me to think bigger, aim higher, and execute with intention. When I decided to pursue Wharton, he was the first person I called — and the one who stayed with me through every step: refining my story, sharpening my resume, and preparing me for interviews with a level of rigor and care that only someone deeply invested in your success would offer. I can say without hesitation that I wouldn’t be where I am today without his guidance. Ossama is the rare mentor who combines strategic insight with genuine humanity, and anyone fortunate enough to learn from him will feel the impact for the rest of their career.

Faisal offered helpful, strategic, and logical feedback throughout my application process. He conducted a detailed review of my final application, including my essays, résumé, transcripts, and more. He helped me identify weak points and showed me how to address them to strengthen my overall application. I felt he truly evaluated my materials through the lens of an admissions counselor, which helped me refine and elevate my application. I was admitted to CBS and have since interviewed with NYU. I highly recommend Faisal.

Caring, thoughtful, and empathetic. I wouldn’t have had my offer to Harvard Business School without his encouragement and advice.
