After nearly a decade in corporate finance in the energy industry, living through its highs and lows. I saw unique pay structures, pension choices, equity awards, and retirement packages make planning decisions far more intricate than most people realize. Five years ago, I set out to become an expert in retirement planning. I apprenticed with seasoned advisors, earned the CERTIFIED FINANCIAL PLANNER® certification, and added advanced credentials in retirement and tax planning to master the strategies that matter most. At Refined Wealth, every process, service, and conversation is built around helping professionals step into retirement with clarity, confidence, and a plan as specialized as their careers.
