Many of the people I work with are thoughtful individuals and families who are building meaningful lives - often while running businesses, raising families, or serving others through their work. In a culture that often glorifies hustle and constant productivity, I help clients step back, clarify what matters most, and make financial decisions that help balance the ideal with the real (aligning long-term hopes with the practical realities of life today). I provide ongoing financial planning and investment management designed to help clients steward their resources wisely. My approach focuses on simplicity, thoughtful decision-making, and long-term alignment between finances and life priorities. That may include conversations around cash flow, taxes, investments, insurance, retirement, or major life decisions, but the goal is always the same: helping clients use their resources in ways that support the life they actually want to live. I enjoy getting to know the people I work with and learning their stories. I’m at my best as an advisor when I know my clients well, and when they know me as well. My role is part guide, part sounding board, and part planner, helping clients think through complex decisions and move forward with confidence. Outside of financial planning, I’m a husband and soon-to-be father who enjoys making pro-level pizza on my Ooni pizza oven, learning from the Bible Project, and playing hockey.
