Running a business is about more than today—it’s about making the right strategic moves for growth, transition, or long-term success. When execution falls behind vision, momentum is lost. Steadfast Ventures partners with CEOs, executives, and boards to turn strategy into action by streamlining operations, retaining talent, and navigating change. Based in New England, I work with organizations across the Northeast, Washington, D.C., and beyond. If you’re at a pivotal moment, let’s connect and build a stronger, more resilient business.
