Zeller Kern Business Advisors

Andrew Kern and David Zeller founded Zeller Kern Business Advisors in 2008, serving business owners and high-net-worth families from their Mequon, Wisconsin headquarters. The firm operates as a registered investment advisor (RIA) and positions itself as a wealth management and business advisory firm — combining financial planning, investment management, and tax strategy for closely-held business owners and corporate executives. Zeller Kern deploys capital across public equities, fixed income, alternative investments, and insurance-based structures, with a focus on tax-aware strategies. Its client base includes business owners preparing for liquidity events, multi-generational families, and corporate executives. The firm structures its allocations around long-term growth, income generation, and risk mitigation — with an emphasis on estate and tax planning integration. Notable portfolio exposures include low-cost index funds, municipal bonds, and direct private placements, though specific holdings are not publicly disclosed. The firm's team includes several Certified Financial Planners (CFPs), Certified Public Accountants (CPAs), and Chartered Financial Consultants (ChFCs), though the total headcount is not publicly stated. Zeller Kern maintains no additional offices outside of Wisconsin. The firm does not operate a formal philanthropic foundation or adjacent investment vehicles, though it advises clients on charitable giving strategies through donor-advised funds and private foundations. Zeller Kern's structural differentiator is its integration of wealth management and business advisory under a single RIA, serving as both financial planner and corporate strategist for business-owner clients. This dual mandate allows the firm to advise on exit planning, succession, and corporate structuring alongside personal wealth management — a model that collapses the typical divide between personal and business financial advice for closely-held entities.

Frequently asked questions

Who runs investment decisions at Zeller Kern Business Advisors?

Investment decisions are overseen by co-founders Andrew Kern (President) and David Zeller (CEO), alongside a team of CFPs and CPAs. The firm uses a committee-based approach to portfolio construction, integrating tax strategy into asset allocation.

How does Zeller Kern source proprietary deal flow?

Zeller Kern does not publicly operate a proprietary deal-sourcing platform. Its investment opportunities typically come through the firm's network of business-owner clients, local accounting and legal partners, and relationships with estate-planning attorneys.

Is Zeller Kern structured as a single family office or multi-family office?

Zeller Kern operates as a registered investment advisor (RIA) serving multiple families, business owners, and executives — effectively a multi-family office in structure. It is not a single-family office tied to one fortune.

Does Zeller Kern participate in fund commitments or only direct deals?

The firm allocates client assets across both fund vehicles (low-cost index funds, mutual funds, and alternative investment funds) and direct individual securities. It also structures custom portfolios for high-net-worth clients, often including direct private placements when appropriate.

Which sectors does Zeller Kern explicitly avoid?

The firm does not publicly list any exclusionary sectors. Its portfolios generally avoid speculative or highly concentrated single-stock positions, favoring broadly diversified, tax-efficient strategies for long-term wealth preservation.

Where does the underlying wealth come from?

Clients' wealth derives largely from business ownership, executive compensation, and multi-generational family assets, concentrated in the Midwest. The firm does not disclose specific family names or wealth origins publicly.

What is Zeller Kern's known posture on co-investments alongside external GPs?

Zeller Kern does not publicly market a co-investment program alongside external GPs. Its direct private placement activity, when it occurs, is structured on a bespoke basis for qualifying clients and typically sourced through local professional networks.
