The Genesis of Grenadilla Advisory: Where Purpose Meets Potential

Every great composition begins with a vision. Grenadilla Advisory was founded on the belief that true wealth is a catalyst for life’s most beautiful compositions – much like Grenadilla, the African blackwood, transforms into musical instruments of extraordinary potential. We invite you to discover the unique journey that led to our firm’s creation.



Meet the Founder

After serving as Chief Investment Officer for a large RIA, Anna Rathbun envisioned a new path for wealth management – one that transcends traditional norms and truly connects with clients on a human level. Her journey spans the world of institutional finance and the expressive artistry of classical music.

Anna, an immigrant from South Korea who came to the U.S. at age nine, intimately understands the journey of transformation. She identifies deeply with the Grenadilla wood itself: seemingly unassuming yet possessing inherent quality to create something extraordinary. This personal experience fuels her passion to empower clients to create their own beauty through their lives, viewing money not as an end, but as a powerful tool.

Recognizing the male-dominated nature of the financial industry, Anna is committed to bringing a crucial female voice, emotional intelligence (EQ), and deep understanding to wealth management. Her expertise spans global economy and markets, interest rate movements, economic and monetary policy, and the intricacies of AI. She’s regularly featured in the media, both broadcast and print, and holds a CFA and CAIA. Beyond the numbers, Anna is a classically trained soprano, infusing her approach with the same compassion and connection she brings to an audience on stage.
