We partner with business-owning families, family members, and family advisors to catalyze more connected and capable families across generations. Connected and capable families recognize that "Your Most Valuable Asset is Who You Are, Not What You Own"TM, so these families optimize relationships. Relationships are like the proverbial mass of the iceberg below the surface of the water -- unseen yet determining the direction of that which is seen. When the relationships involve families who share financial assets, the complexities are magnified. Our "Connected & Capable Family"TM framework supports you and your family to be purposeful in cultivating who are you are individually and collectively, how you engage with each other, and the capabilities you build within your family. A "Connected & Capable Family"TM can build (or re-build) a financial fortune. Yet, money itself can’t (re)build a "Connected & Capable Family"TM. In fact, if not handled skillfully, money can be a detriment to building a more connected and capable family. Were here to be of service. To explore how we can be of service to you and your family, contact us today. Curious About Our Name? "Sankofa" is a mythical bird from the culture of the Akan people of western Africa. The bird is traditionally depicted with its feet facing forward, its head turned backwards, and an egg in its mouth. As it relates to our work partnering to catalyze more connected and capable families, "Sankofa" essentially means: "Here we are today, firmly planted in the present as we draw on lessons from the past to give birth to new possibilities in the future. The concept of "Sankofa" epitomizes family legacy, stewardship, and generational wealth, principles that are core to our work.
