Mastodon Advisory Group
Mastodon Advisory Group was formed in Houston in 2016 as a registered investment adviser. The firm operates from a single address on State Street and lists a single principal, Warren, on its materials — no other investment professionals are publicly identified. Its Fidelity-bonded brokerage is handled through Cambridge Investment Research, disclosing registrations in Texas and Florida. The advisory constructs fee-based portfolios for individuals and charitable organizations while bundling special-needs trust planning into the same engagement. The platform covers public securities — equities and fixed income — executed via Cambridge's broker-dealer infrastructure. Mastodon does not publish a specific asset-class mix, though its RIA registration implies discretionary management across standard liquid-market instruments. The firm's own site does not name any direct alternative-asset positions, private-company stakes, or external fund commitments, and no primary-source reporting names specific portfolio holdings. Total assets or deployment are undisclosed; the firm has never publicly released an AUM figure, and no regulatory filing fills the gap. Mastodon lists a single Houston office with no additional locations. Its compliance filings note status as a Texas-domiciled RIA with an SEC-registered broker-dealer affiliate, but the firm discloses no parallel vehicles, philanthropic arms, or operating companies. No dated operational events are identifiable in the last 24 months from primary sources, and the firm has not announced any personnel changes or strategic moves during that window. Mastodon's structure departs from generic RIAs in one repeatable way: the special-needs trust mandate is advertised as a core service line, not a referral or bolt-on. Most registered investment advisers route families to outside attorneys or trust companies; Mastodon maintains the trust-planning function internally alongside portfolio management, making the firm's Texas-and-Florida registrant footprint a legal-entity bridge between investment discretion and fiduciary trust administration.

Frequently asked questions
Who runs investment decisions at Mastodon Advisory Group?
The firm's website identifies only one principal — Warren — with no further investment committee or named portfolio managers disclosed. The contact email is warren@mastodonllc.com, suggesting all investment and advisory decisions flow through a single individual. No additional bios, backgrounds, or team members are published.
Is Mastodon Advisory Group structured as a family office or a standard RIA?
Mastodon is legally a Registered Investment Adviser, but its boutique model — a single principal, a narrow special-needs trust focus, and no marketed third-party client-acquisition strategy — aligns operationally with a multi-family office serving a concentrated set of private households. The firm does not hold itself out as a family office, and no wealth-origin disclosure makes the characterization precise.
Does Mastodon Advisory Group participate in fund commitments or direct deals?
There is no primary-source evidence that Mastodon commits to third-party funds or pursues direct private-company investments. Its disclosed infrastructure runs through Cambridge Investment Research for brokerage, consistent with a liquid-markets, separately-managed-account model rather than a private-markets allocator.
What is the relationship between Mastodon Advisory Group and Cambridge Investment Research?
Cambridge acts as Mastodon's broker-dealer, not its parent or affiliate. Mastodon's RIA is legally separate; Cambridge's registration provides the underlying securities execution, custody, and FINRA/SIPC coverage. The supervisory office at 1710 State Street in Houston serves both entities.
Does Mastodon Advisory Group manage special-needs trusts in-house?
Yes. The firm markets special-needs trust planning as a primary service line and lists it alongside its investment management platform. Unlike many RIAs that refer clients to external trust companies or law firms, Mastodon appears to keep trust planning within the advisory practice, though it does not specify whether it serves as corporate trustee or simply as an investment manager for trustee-directed accounts.
