About

1834 Investment Advisors provides discretionary and non‑discretionary investment management, ongoing financial planning, and retirement plan services to a mix of high‑net‑worth individuals and institutional clients, including pension plans, trusts, estates, charitable organizations and other plan sponsors. The firm also offers private investment consulting and access to alternative investment models through a third‑party platform.

The firm structures client relationships around a written Investment Policy Statement and emphasizes asset allocation and customized portfolio strategies across equities, fixed income, ETFs and alternatives, with regular portfolio reviews and client consultations; discretionary management is the firm’s primary service. 1834 uses internal and externally sourced models (including strategies developed by its affiliate) and may hire sub‑advisers to implement specific strategies or alternative investments.

What distinguishes 1834 from many peers is its ownership and operating relationships: it is a wholly owned subsidiary of Old National Bancorp and works closely with Old National Bank (including shared employees and provision of proprietary model strategies to the bank), and it discloses potential conflicts where it or its affiliates may have financial interests in private investments it recommends. The firm also highlights specialized services such as management of cash‑balance defined benefit plans and a private investment consulting program that includes due diligence support and administrative coordination.

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.

Find your advisor

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
