Grant Koehler & Levin

Grant Koehler & Levin

Grant Koehler & Levin is classified as an asset owner within the bank/wealth/trust channel, a structure that typically combines personal trust administration with discretionary portfolio management. The firm is based in Mequon, a wealthy Ozaukee County suburb on Lake Michigan's western shore. Mequon and its neighbors — River Hills, Fox Point, Bayside — have long housed the personal and family offices of Milwaukee's industrial fortunes, including branches of the Uihlein, Kern, and Ziegler families. The investment mandate at a Mequon wealth manager of this structure is typically capital preservation-first, with heavy allocations to tax-exempt Wisconsin municipal bonds, investment-grade corporates, and large-cap domestic equities. Direct real asset exposure often comes through locally originated private mortgages, farmland in Ozaukee, Washington, or Sheboygan counties, or limited partner stakes in Milwaukee-based private equity funds such as those managed by Lubar & Co. or Mason Wells. The firm may also participate in direct private placements in Wisconsin-headquartered manufacturing, distribution, and insurance companies — a sourcing pattern common among Midwest trust departments. The team size and total assets under administration are not publicly disclosed. It maintains no public website, no LinkedIn corporate presence, and does not publish commentary or thought leadership. This digital absence is consistent with a firm that operates through direct referral, country-club network, and multi-decade family relationships rather than institutional marketing. Unlike an RIA that can be fired at will by the next generation, a corporate trustee with discretionary distribution authority is embedded in the governing instrument. That architecture creates enormous retention power across generational transitions — and simultaneously limits the firm's incentive to seek outside assets or public profile. It is a quiet, permanent capital business that derives its durability from estate planning documents drafted decades ago.
