Testimonials
I spent twenty years inside Major League Baseball, and I've since consulted in baseball and hockey. This is what the people I worked with and for have to say.
Zack’s contributions gave us the confidence to be bold at the trade deadline, acquiring key players who directly impacted our World Series victory. His impressive ability to connect with our people fostered trust and helped us turn analytical insights into action. I highly recommend partnering with Four Rings for their invaluable perspective and expertise.
When we worked together in Boston, Zack was an important, different perspective in our decision-making process. He made well-articulated arguments backed up with objectivity. Now, Four Rings allows him to bring a fresh viewpoint with strong problem-solving skills to clubs across all sports. He’ll positively impact any organization.
Zack is unique in that he thinks from a big-picture strategy perspective while simultaneously offering practical and realistic steps to improve. He helped us with technology, data science, organizational design, and finding good people. The fact that success follows the teams he works with is not a coincidence.
Zack gave me a lot of ideas, and we talked almost every day. He works hard, listens, communicates clearly, and is open minded. He gets it that both analytics and years of on-field experience are important to winning.
Zack’s ability to create innovative and impactful data-driven processes has always stood out. He not only has the experience and expertise to set up an elite data analytics department from scratch — the hiring, the technology, the structure, the management — but he also understands the big picture and how best to integrate objective decision-making into the broader operation. A proven winner and great teammate, Zack would be an asset to any organization seeking to better itself and establish a competitive edge.
Zack did an excellent job for us. He modernized our baseball operation through a large-scale expansion of R&D and an infusion of innovative thinkers into various departments. He hired talented leaders and created a collaborative culture, empowering people to voice their opinions and participate in healthy debate. He welcomed traditional and novel perspectives, genuinely listened to them, and then distilled the vast information into good decisions.
For nearly two decades in Boston, Zack was an integral part of one of the most successful front offices in sports. As a division rival, I respected his work; when I became his colleague, I got to see firsthand the intellect and mindset behind it. Beyond his contributions to four championship teams, the Red Sox family had in Zack both a conscientious manager of people and a loyal friend and teammate. His influence on the baseball operation here was profound.
Zack has a sharp analytical mind and is an independent thinker. He is able to tune out noise, critically assess complex operational issues, and effectively communicate logical solutions. He is a strong team builder, with much experience identifying, developing, and empowering talented staff. Zack helps create and enhance a collaborative culture fueled by intellectual curiosity and the desire to build competitive advantages.
There’s a special camaraderie you develop with people who have worked alongside you for a long time. Zack is one of those people. For more than a decade, I had a front row seat to his career development and experienced firsthand his depth of knowledge, ability to really listen and hear people, and the emphasis he put on cultivating relationships and connecting with his colleagues and his team. He’s one of the most capable people I know.
