## About

Westco Advisory Services was established in 1984 and maintains its sole office in Lynbrook, New York, a village in Nassau County on Long Island. The firm operates as a registered investment adviser, serving individuals, high-net-worth families, trusts, and corporate entities. Its founding predates the consolidation wave that swept independent RIAs into national aggregator platforms — a four-decade independent streak that implies either a stable, multi-generational client base or a deliberate choice to stay small. Westco's service model centers on discretionary portfolio management and holistic financial planning. The firm typically builds portfolios from individual equities, bonds, mutual funds, and ETFs, allocating across US large-cap, fixed-income, and occasionally international developed-market exposures. While Westco does not publicly disclose a dedicated alternatives or private-markets capability, its fiduciary structure permits it to evaluate client-specific opportunities in real estate, private placements, and tax-advantaged municipal bonds. The firm's geographic focus remains concentrated in the New York metropolitan area, with no foreign offices or stated international expansion strategy. Its client-facing documentation emphasizes retirement income planning, estate coordination, and intergenerational wealth transfer — the standard toolset of a planning-centric RIA, deployed at a single-site scale. Westco Advisory Services does not publish its assets under management, team headcount, or total client count, making independent scale assessment difficult. Public records confirm the firm's Form ADV registration with the SEC, which classifies it as a small advisory business based on regulatory asset thresholds. Westco maintains no known philanthropic foundation, operating-company affiliation, or club-deal network that would place it in peer-family-office or institutional-investor workflows. No verifiable operational events from the last 24 months are available. Westco's structural differentiator is its unbroken independence across more than 40 years in a market where small RIAs increasingly sell to consolidators or platform aggregators. The firm's survival implies a sticky book of second- and third-generation client relationships, sustained by a planning-first model that competes on trust continuity rather than investment-product breadth. For an institutional allocator, Westco is invisible — it is a local fiduciary, not a capital-raising counterparty. For a peer family office or multi-generational wealth holder evaluating succession-stable advisory models, Westco's single-site, four-decade arc offers a case study in quiet endurance.

## Questions

### How can an institutional allocator verify Westco's regulatory standing?

Westco files Form ADV with the SEC as a registered investment adviser. Allocators can retrieve the firm's most recent filing — including regulatory assets under management, fee schedules, disciplinary history, and service descriptions — through the SEC's Investment Adviser Public Disclosure website. The firm's CRD number and ADV Part 2 brochure are public record.
