Grant Koehler & Levin

The firm is classified as an asset owner within the bank/wealth/trust channel. This designation typically means it operates as a state or federally chartered trust company, or as the trust department of a community bank, providing personal trust administration, estate settlement, custody, and discretionary investment management. Trust-chartered entities in Wisconsin are regulated by the Wisconsin Department of Financial Institutions and can serve as corporate trustee, co-trustee, or agent for trustee for irrevocable trusts, charitable remainder trusts, and private foundations.

The named principals and investment committee members are not publicly disclosed. Investment decision-making at a trust-company structure of this size typically sits with an internal trust investment committee, often comprised of senior trust officers and external directors with local business and legal backgrounds. External investment advisory relationships may supplement the committee for specific asset classes.

The firm is based in Mequon, Wisconsin, an affluent North Shore suburb of Milwaukee. This geography is home to significant legacy industrial wealth — including the Uihlein (Schlitz Brewing), Kern (Generac), and Ziegler (Ziegler Companies) families — as well as second- and third-generation manufacturing and distribution fortunes. A trust company in this location likely administers assets for those family branches, as well as for Milwaukee-based corporate executives, law firm partners, and medical practice owners who have migrated north from the city.

If it follows the pattern of similarly situated Midwest trust companies, its private-market exposure is modest and relationship-driven. Direct co-investments or LP commitments would likely flow to Wisconsin-based private equity firms such as Lubar & Co., Mason Wells, or Baird Capital, typically via long-tenured personal relationships between trust officers and fund managers rather than a formal alternatives program.

No. The firm is categorized as an asset owner with a bank/wealth/trust subtype, which serves multiple unrelated families and individuals. It is not a single-family office. However, in its market, it may effectively function as the outsourced family office for several local families whose trust instruments name Grant Koehler & Levin as corporate trustee with broad administrative and investment authority.

The firm maintains no public website, no LinkedIn presence, and no thought-leadership marketing. This digital absence strongly suggests a referral-based growth model centered on Milwaukee's estate planning attorneys, CPA firms, and private banks. New relationships likely originate when an attorney drafts a trust instrument naming the firm as successor trustee, or when a family office dissolves and the trusteeship migrates to an established local fiduciary.

There is no public record of the firm engaging in co-investment programs alongside institutional GPs. As a trust-chartered fiduciary, its participation in co-investment vehicles would raise prudent-investor rule considerations under Wisconsin's Uniform Prudent Investor Act, particularly around concentration limits, illiquidity matching with distribution requirements, and fee layering. It is unlikely to be an active co-investor absent a very specific and long-standing GP relationship.
