After nearly a decade in corporate finance at Phillips 66, I now help high-income professionals and their families with investment, tax, and retirement planning. Before launching Refined Wealth, I completed the CFP® education program at Rice University and gained hands-on experience at two Houston firms, where I was part of teams that collectively served over 250 families and oversaw more than $650M in client assets. I also earned advanced certifications in tax planning (TPCP®) and retirement income planning (RICP®) to deliver more targeted advice. Now I’m building the firm I’d want for myself, my family, friends, and former colleagues. Most of my clients are: ◻︎ High-income professionals (O&G, medicine, sales, dual-income households) ◻︎ Retirees with complex assets and income sources ◻︎ Families navigating liquidity events (real estate sales, inheritances, business exits) Refined Wealth is an independent, fee-only fiduciary firm built on transparency and alignment. No product sales. No commissions. If this resonates, let’s connect for a complimentary introductory call to see if we’re a fit.
