𝐎𝐮𝐫 𝐚𝐩𝐩𝐫𝐨𝐚𝐜𝐡 is to build generational wealth delivered through the highest standard of service and execution. We do this by adhering to a clearly defined client standard of care—one designed to provide confidence, clarity, and continuity across every stage of your financial life.

Exclusivity. Personalized service and direct access through a deliberately limited client base.

Continuity. Long‑term planning for you and your family across generations.

Predictability. Disciplined, insight‑driven decisions designed to provide clarity and confidence.

𝐎𝐮𝐫 𝐩𝐫𝐨𝐜𝐞𝐬𝐬 centers on three essential components that align your capital with your risk profile, goals, and long‑term growth opportunities.

Risk Profile. Your financial plan defines your personal risk profile and guides all investment decisions.

Allocation. Portfolios are built across equities and fixed income, with selective use of alternatives.

Strategic Emphasis. Capital beyond the core portfolio may be allocated to the Bristol Bay Partners Growth Portfolio, an actively managed medical technology strategy led by Mark Rethlake.

My path into wealth management has been shaped by a career grounded in analytical thinking and complex investment decision‑making. I began with a foundation in chemistry, where I developed an appreciation for how disciplined, well‑considered inputs—applied intentionally over time—can produce durable outcomes. That perspective carried forward into my work in commercial real estate, advising building owners and asset managers across the Midwest on high‑value, long‑term investment decisions.

In commercial real estate, I worked closely with principals navigating capital allocation, leasing strategy, financing, and portfolio positioning. These environments involved meaningful risk, long time horizons, and decisions where outcomes were shaped as much by planning and coordination as by market conditions. Those experiences continue to inform how I approach investment strategy, risk management, and the importance of an integrated plan.

What became increasingly clear was that behind every transaction and balance sheet stood an individual, a family enterprise, or a business owner weighing decisions that carried real financial and emotional weight. That realization ultimately led me to wealth management, where I could work more directly with families and founders facing similarly complex, high‑impact decisions—but across the full scope of their financial lives.

Today, I partner with high‑net‑worth individuals, families and business owners to bring clarity, structure, and continuity to their financial lives. My approach is centered on understanding the interconnected aspects of a client’s financial world—investments, business interests, balance sheet, tax considerations, and long‑term goals—and aligning them into a cohesive strategy built for longevity. Whether advising through liquidity events, portfolio transitions, generational planning, or strategic investment decisions, my role is to help clients simplify complexity and move forward with confidence. I strive to serve as a steady, objective partner—helping clients protect what they’ve built, make intentional decisions, and ensure their wealth supports the life, legacy, and enterprise they envision.

My grandfather was a farmer in Iowa. He was soft spoken and lived a simple life. What no one knew, not even my grandmother, was that he was a savvy investor. He had been acquiring farm land and investing in the stock market for over 35 years. When he passed away in 1997, my grandmother was not prepared for the responsibility of managing those assets. The entire family had to organize the investments. Shortly after his death, my grandmother was diagnosed with dementia and needed hospice care. Because of my grandfather’s investments, we had the capability to give her the care she needed and deserved. That was the beginning of my involvement in wealth management. One could say the reason I do what I do is because I love to help people navigate financial challenges and build wealth for their families. My grandfather taught me well.

Two brothers. One inheritance.

How will their story unfold?

Inheritance is about more than money. It’s about navigating family, history and your future. See how two brothers decide what to hold onto, what to let go and how to move forward.

If you’re going through a wealth transfer event like an inheritance, death or divorce, our experienced guidance can help give you more confidence.
