What Inspires Me: My clients inspire me. As I meet with them, whether to complete an annual review or to discuss how an event has made them re-think their strategies, I marvel at how their lives inspire me to re-evaluate how I live mine. I know that these interactions continue to help me improve as a human being and financial advisor, which in turn, make me even better at helping my clients meet their financial goals. I will never stop learning thanks to the clients I have been introduced to, and the ones I will meet in the future.
