Chief Igniter
Igniting the culture and strategy needed to turn complex challenges into sustainable value
Jarett brings more than 25 years of experience leading organizations through pivotal growth, business development, and transformational change. He specializes in turning high-level strategy into measurable, real-world results. Throughout his career, he has built a reputation for guiding complex initiatives, optimizing operational execution, and empowering teams to navigate change with confidence and clarity.
He believes that successful transformation requires much more than just a vision—it demands disciplined planning, data-driven insights, and a culture that embraces continuous improvement. An enabling and collaborative partner, he works closely with executive teams, boards, and stakeholders to solve intricate business challenges and deliver sustainable, optimistic outcomes.
Having spent a significant portion of his career working alongside several of the Infinite Green Chiefs, he developed a deep-rooted appreciation for the power of authentic partnerships and customer-centric solutions. In the summer of 2025, he began his journey back into consulting by reconnecting with the Infinite Green team. The firm’s commitment to truly understanding client challenges, building human connections, and doing the hard work to drive meaningful culture made the role of Chief Igniter a natural fit for his standout talent.
Outside of work, he brings that same energy to his personal life by staying active and connected to nature. Whether he is on the golf course, in the mountains, or exploring the great outdoors, he values the fresh perspective that comes with being outside. He is also deeply passionate about giving back to his community, routinely dedicating his time to volunteer service and supporting nonprofit organizations that make a lasting difference.
