Kyle H

CFP®

Kansas City, MO

Hill-Top Financial Planning, LLC

Most people don't need another investment salesperson—they need a trusted guide to help them make smart financial decisions. Many of the families I work with are doing a lot of things right. They're earning a good income, saving for retirement, investing consistently, and building a life they love. Yet they still wonder: Am I paying more in taxes than necessary? Are we making the most of our opportunities? Are we actually on track for retirement? That's where comprehensive financial planning can make a difference. As a CFP® professional and fee-only fiduciary, I help individuals and families create a coordinated strategy around taxes, retirement, investments, insurance, estate planning, and cash flow. While many advisors focus primarily on investments, I believe some of the biggest opportunities often come from proactive tax planning and making sure every financial decision works together toward your goals. My goal isn't simply to help you build wealth. It's to help you keep more of what you've worked hard to earn and use it intentionally to support the life you want to live. Outside of financial planning, I'm a husband, father of three, and youth baseball coach. Like many of my clients, my family spends plenty of evenings and weekends at practices, games, tournaments, and other activities. Because of that, I have a special appreciation for the financial decisions parents face as they balance retirement goals, family priorities, and opportunities for their children. Whether you're raising competitive athletes, preparing for retirement, navigating a career transition, or simply looking for a trusted partner to help you make sense of it all, my goal is to provide clear advice, thoughtful planning, and ongoing guidance every step of the way.
