Our Purpose

We deliver holistic, comprehensive counsel for clients facing complex legal and personal transitions — ensuring legal, financial, and family needs are addressed as one.

Estate planning, benefits, care arrangements, and fiduciary responsibilities rarely arrive in isolation. Our Washington, D.C. practice is built to resolve them together — proactively, and with the dignity these decisions deserve.

Side by Side

We sit on the same side of the table.

Every plan begins as a conversation. We work through documents together — explaining each decision, weighing every option, and making sure you understand exactly what you’re signing and why.

The result is a plan you helped shape, not one handed to you — and a counselor who stays in your corner long after the ink is dry.

Common Questions

Answers before we begin

There is rarely a wrong time. If you own assets, have children, or want a say in your medical and financial decisions, a plan protects you now and your family later. We help clients plan proactively so decisions are never left to a court.

Yes. While our office is in Washington, D.C., our attorney is admitted in D.C., Maryland, and New York, and we routinely coordinate multi-jurisdictional estate and administration matters for families across the country.

A will directs how your assets are distributed and takes effect through probate. A trust can hold and manage assets during your life and after, often avoiding probate and offering greater privacy and control. We help you choose the right combination for your goals.

Yes. For clients with significant assets, real property, or complex holdings, we can serve in fiduciary roles such as trustee or agent under a power of attorney, providing continuity and trusted stewardship over time.

Simply bring your questions. If you have existing documents, a rough list of assets, or family details, those help — but the first conversation is about understanding your situation and goals, not paperwork.
