About
Isthmus Partners, LLC is an SEC-registered investment adviser that serves individual and institutional clients, including trusts, pension plans, and business entities. The firm provides discretionary portfolio management, performance reporting, and financial planning and consulting services, offering separate Institutional Portfolios and Counseled Portfolios for individuals.
The firm’s investment process is equity‑centered and committee‑driven: a Domestic Equity Investment Team and Equity Investment Committee meet regularly to apply quantitative “Excess Return Identifier” screens and fundamental analysis, emphasizing quality measured as the spread between ROIC and WACC and using discounted cash flow valuation. Portfolios are constructed with explicit sizing and valuation rules (e.g., buying at discounts to intrinsic value, larger- and small-cap portfolio target counts), and the firm also runs fixed income, international equity, and Core+ mutual fund/ETF strategies.
Compared with many peers, Isthmus highlights performance reporting and publishes performance-related material (including predecessor performance) and also operates as a wrap fee program sponsor—Counseled Portfolios are offered exclusively on a wrap fee basis—while participating as a sub-adviser in the Schwab Adviser Marketplace. The brochure also indicates the firm engages in client education activities and maintains relatively high account thresholds and minimum advisory fees, reflecting a focus on larger, more actively managed relationships.

Not sure where to start?
We'll help you think it through—whether you ultimately need an advisor or not. Warmer helps you compare advisors clearly, so you can choose with confidence.
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. Advisors are independent and may not have reviewed or updated this information. Please review an advisor’s Form ADV and do your own diligence before deciding whether to work with them.
Advisor matching and introductions are provided by FinanceHQ LLC (“FHQ”), a wholly-owned subsidiary of Warmer and an SEC-registered investment advisor. We receive compensation from certain participating advisors for introductions or referrals. This creates a conflict of interest because we have an incentive to recommend advisors who compensate us, including those who pay us more. You pay no fee to use our matching service, and advisor fees are not increased because of a referral or introduction. We do not review the ongoing performance of advisors, manage or hold assets, guarantee performance, or provide advice about specific investments.
By using our service, you agree to our Terms of Service and Advisory Agreement, and acknowledge our Privacy Policy. Please review FHQ’s ADV Part 2A and Form CRS. Logos provided by Logo.dev
