Wysopal Wealth

At Wysopal Wealth, we specialize in helping high-income professionals and former athletes manage the complexities of equity compensation and variable income. Our goal is to make sure your money works for you—today and for the future. We focus on creating personalized, values-driven financial plans that allow you to live fully now while planning for what’s next. I’m Brett Wysopal, a proud girl dad of two and a former minor pro hockey player. My experience in sports taught me discipline, focus, and resilience, all of which I apply to financial planning. After spending years navigating the world of equity compensation, I’ve made it my mission to help families simplify their finances, reduce tax burdens, and achieve their life goals. Our approach at Wysopal Wealth is rooted in personalized attention. We keep our client list small, ensuring every client receives the time and care they deserve. We dive deep into your financial situation, understanding your numbers, values, and what matters most to you. This allows us to tailor your financial strategy to your unique goals, whether that’s managing your equity, preparing for retirement, or planning a family legacy. Equity compensation is often the largest part of our clients' wealth, but it comes with complexities—ISOs, RSUs, stock options, and significant tax implications. Many people wait too long to make decisions about their equity, resulting in missed opportunities or unexpected tax bills. At Wysopal Wealth, we take a proactive approach, creating a strategy for when and how to execute your equity plans, minimize tax liability, and diversify your holdings. At Wysopal Wealth, financial happiness is the goal. We believe that money should support the life you want, and we’re here to help you make that happen.
