I’m thrilled to recommend Aaron Birnbaum as a coach on JoinLeland.com. Aaron is an exceptional cybersecurity expert—a CISSP-certified professional with an MBA and decades of experience, from shaping security strategies for Fortune 100 companies to founding TRaViS ASM, an innovative attack surface management platform. His technical depth spans frameworks like NIST, CMMC, and HIPAA, and he’s a gifted speaker who’s educated global audiences on security awareness, social engineering, and more. Working with Aaron has been a game-changer for me. His ability to break down complex cybersecurity concepts into actionable insights is unmatched—I’ve learned a ton from him, both as a friend and a mentee. He’s approachable, insightful, and genuinely passionate about helping others succeed. Whether you’re a startup founder needing a vCISO or a professional aiming to level up your security skills, Aaron’s expertise and mentorship will deliver immense value. The world deserves access to his knowledge, and I can’t recommend him highly enough as a coach.

Stephen is the number one reason I landed an internship and job at Bain. He helped me practice cases and prepare for interviews. I did practice cases and preparation with several coaches, but Stephen was by far the most helpful. He was able to thoroughly analyze my performance and highlight specific areas for improvement while also providing specific advice, strategies, and help to be able to consistently implement the improvements. He was direct and firm, but also caring and compassionate. Stephen is the best consulting prep coach I’ve ever seen.

Amanda comes with a strong product and user focused background. I've had the privilege of working with her on many complex features and have seen her navigation through incredibly tough situations with ease. Trust her to shed light on how to be a good product builder and a mentor to everyone around her.

Stephen helped me land a consulting role at PwC and Gartner! He is an analytical thinker and gives great insight as to how to approach complex issues. After casing with him, I felt much more prepared to do my interviews and received great feedback from those I talked to. Being able to practice a skill I had not previously been savvy to was instrumental to my success- he works with people where they are at and helps build them up to tough cases, until they have mastered the practice.

Stephen is an amazing one of a kind coach. I’ve worked with him in multiple instances over 5+ years, mostly navigating career moves and negotiations. Stephen helped me do due diligence in exploring and applying for roles in management consulting as well as product management. He also assisted me in preparation for interviews and in staying up to speed on industry trends and valuable insights for promo negotations.

Ryan is among the most caring and intelligent peers I've met at business school. I know many people benefit from his coaching and guidance and land in their ideal roles.

Ryan is one of the most generous, thoughtful coaches you’ll ever meet. He truly cares about his students and will always go the extra mile for them. Highly recommend the chance to work with Ryan!

I went to business school with Ryan and he is incredibly knowledgeable about finance recruiting and willing to go above and beyond to help others.

Ryan is the ideal coach! He is incredibly knowledgeable in both the industry and broader recruitment world. And moreover he's an intelligent, kind and naturally extremely helpful person who genuinely enjoys helping others to achieve their potential.

Nariman is an outstanding mentor who had guided my career from its birth to the heights it has reached now. She's tremendous at recognizing potential and directing that potential towards achieving milestones. I am forever indebted to her.
