Drummond Woodsum & Macmahon PA Profit Sharing Plan
The plan is the tax-qualified retirement vehicle for Drummond Woodsum, a full-service law firm founded in Maine and now operating from four offices including Portland, Manchester, Lebanon, and Flagstaff. The firm's profit-sharing plan exists to provide deferred compensation for its attorneys and consultants, drawing contributions from the firm's operational revenue. Unlike multi-employer or public pension systems, the plan's participant base remains tied exclusively to the firm's own professional staff. The plan's reported assets include Master Trust Investment Accounts and participant loans, suggesting a pooled trustee-directed structure alongside self-directed borrowing provisions common in professional-service profit-sharing plans. While the plan does not disclose specific investment mandates, comparable law-firm retirement vehicles typically allocate across public equities, fixed income, and real estate, with limited direct private-market exposure. No direct co-investments, SPVs, or venture commitments have been publicly identified. The plan is administered from the firm's Portland headquarters, with plan participants drawn from all active firm locations. The law firm itself comprises over 100 attorneys and consultants, with practice areas spanning tribal law, education, real estate, and commercial services. In May 2026, the firm was named to Vault's "Top 150 Under 150" list of leading midsize law firms, providing a marker of the sponsoring entity's market standing. Law-firm profit-sharing plans operate under a distinct governance model compared to corporate 401(k) plans or union pension funds. The plan's trustees are typically the firm's managing directors, aligning investment oversight directly with the partnership's own long-term interests. David Kallin and Benjamin Marcus hold the top management roles as of 2025–2026, suggesting continuity in the plan's stewardship as the firm navigates growth in its tribal lands and conservation practices.

Who is responsible for investment oversight at the plan?
The firm's Managing Directors — currently David M. Kallin and Benjamin Marcus, as identified on the firm website and Altss research — typically serve as the plan's trustees. In law-firm profit-sharing structures, the managing partners or a board committee retain direct fiduciary authority over plan assets.
How does the plan's asset structure operate?
Public filings indicate the plan holds Master Trust Investment Accounts along with participant loans. This structure suggests pooled trustee-managed accounts alongside a self-directed loan feature, which is standard for professional-service profit-sharing plans where partners and associates can borrow against their vested balances.
Does the plan participate in venture capital or direct private investments?
No publicly available information indicates the plan makes venture capital commitments, direct co-investments, or special-purpose vehicle allocations. Its reported asset categories are limited to Master Trust Investment Accounts and participant loans, consistent with a conventional trust-managed retirement pool for a law-firm partnership.
What role do the firm's non-legal operations play in the plan?
Drummond Woodsum's profit-sharing plan is funded entirely by the law firm's own revenue, which is generated across practice areas including tribal law, K-12 education, real estate, and commercial services. The firm's conservation work and tribal-nation representation contribute to its financial base, indirectly supporting plan contributions.
How is the Maine tribal-nation work related to the retirement plan?
The plan's sponsoring firm — Drummond Woodsum — has a significant tribal-law practice, including representation of the Passamaquoddy Tribe in carbon-credit sales and advocacy for tribal sovereignty. While the plan does not directly invest in tribal enterprises, the firm's revenue from these representations underpins contributions to the profit-sharing pool.
