About
Guardian Investment Management serves primarily individual and high‑net‑worth clients, and also advises trusts, charitable foundations, retirement plans, estates, and corporations. The firm provides discretionary investment management and separate account portfolio oversight, delivering quarterly valuations and relying on client-selected custodians.
The firm follows a conservative, long‑term investment philosophy focused on capital preservation and protection from inflation, relying on fundamental analysis of company financials, industry conditions, and macro factors. Its core equity approach screens the largest U.S.-traded, G7-domiciled companies to a shortlist from which 30–35 holdings are selected, and the firm may use covered-call strategies to manage concentrated positions or generate incremental yield.
What is distinctive about the firm is its scale relative to staff: it manages roughly $310 million in client assets with a single advising partner, an uncommon AUM‑per‑advisor profile among peers. It is a longstanding, multi‑generational boutique (founded in 1976) that typically implements balanced allocations (commonly 60–70% equities and 30–40% bonds/cash), enforces a $1 million guideline for new accounts with exceptions on occasion, and generally operates on a fully discretionary basis while recommending independent custodians.

Advisors at this firm
Not sure where to start?
We'll help you think it through – whether you ultimately need an advisor or not.
Warmer provides personalized recommendations and introductions to independent fiduciary advisors. We do not supervise advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
Each advisor listed on our site is an independent fiduciary responsible for their own advice. Warmer may receive fees from advisors for participation or referrals; these fees are paid by advisors and do not affect the fees clients pay for advisory services.
For advisor listings, we rely on sources including public filings and data provided by advisors, and we cannot guarantee that all information is current or accurate. Please review an advisor's Form ADV and do your own diligence before entering into an advisory relationship.
