When I was 18 years old, I was shown how compound interest and time can impact people’s financial lives and, more importantly, retirement. Since then, I have thoroughly enjoyed helping people in all seasons of their financial life, whether they’re just getting started with investing or have recently retired. Since I started in the profession in 2016, I’ve witnessed a lot of friends receive poor financial advice from other advisors. That has encouraged me to make sure that doesn’t happen to any peers of mine anymore. Working as a fiduciary, I provide advice in the best interest of our clients, and I am confident that the financial planning and service we provide at Flagstone are top-tier. Born and raised in Lincoln, Nebraska, I grew up as a huge Nebraska Cornhusker fan and rarely miss home basketball and football games. I have been a sports fanatic my whole life and continue to primarily play golf, basketball, and tennis. I love cocktail hours, great food, and even better company — all of which I get to enjoy at Sunday night dinners with my grandparents. Those weekly family gatherings are the highlight of my weekend and a great start to the week.

My professional journey has focused on law and financial planning. After graduating from the University of Nebraska College of Law in 1999 and practicing at a private firm, I became in-house counsel and compliance director for a regional investment firm. Recognizing the lack of comprehensive financial planning, I transitioned away from the corporate counsel role into a financial planning role. I obtained my CFP® certification early in my career, which allowed me to adopt a holistic approach to financial planning — considering every facet of our clients’ financial life while keeping their unique goals and objectives at the forefront. The founding of Flagstone Financial Management stemmed from a desire to address the gaps in traditional investment management and financial planning. While many investors receive investment advice, they often don’t receive true comprehensive financial planning. Thus, our team at Flagstone strives to provide a comprehensive suite of services that cater to the diverse needs and aspirations of our clients. When I’m not immersed in work, I enjoy spending quality time with my family: my wife Jill and our two children, Sam and Sophie, along with our beloved Labrador retriever, Royal. We enjoy the simple pleasures of grilling outside, walking in our neighborhood or at local parks, and playing tennis or golf together. Dedicated to lifelong learning, I’m usually listening to an audio book, podcast, or video when exercising our dog or relaxing at home. My family and I are proud University of Nebraska fans and love to cheer on the Huskers every chance we get.

When my wife and I were newlyweds (and before I was in the financial planning profession), we got some bad financial advice from a few different financial “advisors.” With little knowledge of how different compensation structures worked, we trusted people who were really selling a product instead of providing advice in our best interest. Now, I help people avoid some of the same mistakes I made. As a fee-only planner, I help clients determine whether they’re on track to meet their goals, and, if not, I form recommendations to make some adjustments to get them back on track. I’ve lived in Lincoln, Nebraska, for nearly my entire life. I married my wife Kate in 2013. We have three young children, so my home life is presently both a ton of fun and a ton of work. We also have two Balinese cats named Neville and Luna after some of our favorite Harry Potter characters. I love traveling to new destinations and enjoy saving money on traveling by using points almost as much as I love traveling itself. I’m also passionate about good food, good drink, and good music.
