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.
About Grenadilla Blackwood

Grenadilla is an African blackwood used to make high performance woodwind instruments such as oboes and clarinets. Its natural properties include a smooth and dark surface and resistance to moisture that render the wood resilient to the condensation produced during the music-making process. From a tree in the southeastern African grasslands to the performance halls all over the world, grenadilla is an unassuming wood whose purpose culminates in creating the ultimate beauty in this world. We believe that there is a meaningful parallel between grenadilla and how we live our life’s purpose: strength, resilience, and grace that ultimately create beautiful music, the way you want to write your life’s narrative.
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.
A Philosophy of Independence
At the heart of our investment culture is independence – not just in how we are compensated but in our industry relationships. Objective assessment of investments and the asset allocation implementation of in-house views drive the investment process at Grenadilla. In both private and public markets, we bring this institutional-quality experience directly to our clients. Our investment managers earn the privilege of putting your assets to work because they have gained our professional confidence in doing the best job for you, not because of industry affiliations. This unwavering independence ensures your portfolio is genuinely designed for your unique aspirations, not just off-the-shelf solutions.
