About
The Delta Group provides discretionary portfolio management and related financial planning primarily to individual households, reporting 29 client accounts that include 12 high‑net‑worth and 17 non‑high‑net‑worth clients. The firm reports $49.2 million in regulatory assets under management and delivers advisory services directly to individual clients rather than through pooled investment vehicles.
The brochure indicates the firm manages accounts on a percentage‑of‑AUM fee basis and lists core activities such as portfolio management for individuals and small businesses, financial planning, and the selection of other advisers. At year‑end the firm reported an asset mix concentrated in exchange‑traded equities (54%) and U.S. government/agency bonds (35%), with smaller allocations to municipal bonds, non‑investment‑grade corporate bonds and cash.
A distinctive operational feature is that the firm’s principals are registered representatives of Oak Tree Securities and are independent insurance agents licensed in California — arrangements the ADV discloses and that are uncommon among similarly sized supported firms. The brochure also notes the firm operates with a very small staff and maintains books and records with named individuals and an outside bookkeeper; these staffing and business‑affiliation details are presented as material disclosures and may give rise to conflicts of interest that clients can review in the ADV.

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
