Creegan & Nassoura Financial Group, founded 2004, is a Portsmouth-based wealth manager serving individuals and trusts across coastal New England.

Creegan & Nassoura Financial Group

Creegan & Nassoura Financial Group was founded in 2004 by John Creegan and Robert Nassoura, establishing a practice focused on investment advisory and financial planning services in Portsmouth, New Hampshire. The firm operates as a boutique wealth manager serving individuals, high-net-worth families, trusts, and small businesses, with an emphasis on integrating portfolio management with estate planning strategies. The founding team brought a Main Street advisory model to the Seacoast region, building a practice around long-term client relationships rather than institutional asset gathering. The firm's investment approach centers on personalized portfolio management, blending asset allocation across equities, fixed income, and cash equivalents tailored to individual client goals. Creegan & Nassoura does not market a proprietary fund or institutional strategy; instead, it constructs portfolios using individual securities and third-party vehicles appropriate for each client's risk profile and time horizon. Its service offerings extend to comprehensive financial planning, retirement income strategies, and estate planning coordination, positioning the firm as a generalist advisor rather than a thematic or sector-specific investor. Geographic focus remains concentrated in New Hampshire's Seacoast region and southern Maine. As a small practice, Creegan & Nassoura operates with a lean team — likely fewer than ten professionals — from a single office in Portsmouth. The firm does not disclose assets under management or deployment figures, consistent with its profile as a privately held, non-institutional wealth manager. No adjacent vehicles, philanthropic foundations, or co-investment clubs are publicly associated with the firm. Recent regulatory filings remain consistent with a steady-state advisory practice, with no public announcements of mergers, acquisitions, or strategic pivots. What distinguishes Creegan & Nassoura is structural rather than strategic: it occupies the vast but rarely profiled tier of American wealth management — the local, relationship-driven RIA operating far from the family-office and institutional aggregator spotlight. This architecture prioritizes continuity and estate integration over scale, making it representative of a model that manages a significant share of private wealth without ever appearing on allocator shortlists.

Frequently asked questions

Who runs investment decisions at Creegan & Nassoura?

The firm is led by its founding principals, John Creegan and Robert Nassoura, who jointly oversee investment advisory and portfolio management decisions. The practice operates as a small, principal-led RIA, meaning clients work directly with the founders rather than through a layered investment committee. Specific individual roles are not publicly detailed, consistent with the firm's low-profile posture.

Does Creegan & Nassoura manage proprietary funds?

No. The firm constructs client portfolios using individual securities and third-party investment vehicles rather than offering proprietary funds. Its regulatory stance is that of an investment advisor, not a fund manager — it does not sponsor pooled investment vehicles or market a house investment strategy.

What client types does the firm serve?

Creegan & Nassoura provides advisory services to individuals, high-net-worth individuals, trusts, and businesses. Its practice centers on comprehensive financial planning that integrates investment management with estate planning, retirement strategies, and trust services — a model suited to families and business owners rather than institutional allocators.

Is Creegan & Nassoura a single-family office?

No. The firm operates as a wealth management practice serving multiple clients, not as a dedicated single-family office. While it works with high-net-worth families, its structure and regulatory registration classify it as a Registered Investment Advisor (RIA) open to a range of individual and institutional clients.

How does the firm source its clients?

Client acquisition appears entirely local and relationship-driven, centered on Portsmouth and the New Hampshire Seacoast region. There is no evidence of a national marketing presence, institutional sales effort, or referral network beyond organic community ties. This mirrors the traditional Main Street advisory model in smaller US markets.
