StratFI

I’m Delaware’s only professional futurist and the founder of StratFI, a boutique investment advisory firm built around a simple question: “What happens next?” Before launching StratFI, I served as lead portfolio manager for a multi-family office working with inherited wealth families. At the start of my career, I worked as a financial planner for what is now Ameriprise. Today, StratFI provides active investment management for active people — particularly professionals and retirees focused on building, preserving, and navigating long-term wealth. I work with a limited number of clients to maintain meaningful relationships and deliver a highly personalized experience. Clients receive direct access to their portfolio manager, customized investment strategies, and thoughtful guidance. All client assets are custodied with Charles Schwab. StratFI operates as a fee-only fiduciary, meaning no commissions and no conflicts of interest. To maintain a high standard of service and customization, we typically work with clients who have $500,000 or more in investable assets.
