Integrated business, tax & estate counsel for the DMV

Senior counsel for the decisions that compound.

Thienel Law advises business owners and families across Maryland, Virginia, and Washington, D.C. — integrating business, tax, and estate strategy so each decision strengthens the next.

Integrated counsel

Business, tax, and estate strategy — under one roof.

Most firms treat these as separate matters. Thienel Law treats them as one. With graduate training in economics and an LL.M. in Taxation, Stephen Thienel brings the perspective to see how a contract today shapes your taxes next year and your estate a decade from now — and to plan accordingly.

The attorney

A practice built on perspective
