We write in the margin of significant lives.
30th Century is a private financial management and business administration practice for high-net-worth individuals, families, and the entities that carry their work forward.
Client identity is never disclosed. No case studies, no press, no exceptions.
We don't chase clients, headlines, or trends. We keep books precisely, file calmly, and counsel privately — for a small roster of principals who expect their financial life to be handled with the same craft as the rest of it.
What we look after.
Family Office Accounting
Consolidated reporting across personal holdings, trusts, and operating entities — one source of truth for your wealth.
Entity Management
Bookkeeping, controllership, and compliance for LLCs, partnerships, S-corps, and investment vehicles.
Tax Strategy & Filing
Multi-jurisdictional planning, K-1 coordination, and quietly aggressive structuring within the four corners of the code.
Private CFO Services
Cash management, capital calls, investor reporting, and the disciplined oversight a serious balance sheet deserves.
A relationship begins with a conversation.
We accept a limited number of new principals each year. Introductions are reviewed personally by a partner.
