Since 2004, Velaris have built a wealth advice practice and team focused on investment excellence and what matters to our clients. We integrate strategic modelling, behavioural insight and investment depth to support clarity, confidence and long-term outcomes.
Justin Hooper and Bob White founded Sentinel Wealth in December 2004 to transform the wealth advice experience. Not only did they completely redefine the value and relationships clients now expect from financial advisers, they also set a new standard for independent, evidence-based advice that brings structure to complexity and meaning to wealth.
Today, Justin continues to lead the wealth advice business and team under a different name – Velaris Private Wealth. While we have evolved to offer a more sophisticated set of capabilities, the essence of our approach to wealth advice remains the same. We think clearly about what’s important to our clients and harness all our expertise and resources to exceed their expectations. We are still privately owned, and deliver advice grounded in evidence and wisdom, not product, so our decisions are pragmatic and always aligned with what matters most.
