About the data

Pennsylvania Lobby Guide

The Pennsylvania Lobby Guide is an independent directory of the lobbyists registered with the Pennsylvania Department of State and the principals they represent. It takes the public registration record and makes it something you can actually use: searchable, readable, and up to date.

Every listing comes from the Pennsylvania Department of State, Lobbying Disclosure: public registration export (lobbyists, lobbying firms, principals), 2025-2026 registration period (2025-2026 registration period (current registrations and affiliations; terminated registrations and ended affiliations excluded)). The guide currently lists 1,273 lobbyists and 2,169 principals, with 163 lobbying firms. The data was last refreshed on November 2, 2026.

We publish names, firms and organizations, the principals each lobbyist represents, and city and state. We never publish phone numbers, street addresses or personal email addresses.

Lobbyists can claim their listing for free to add a bio and areas of expertise. Claims are checked by hand against the official record before anything changes.

What you will find here:

• Every registered lobbyist, A to Z, with the principals they represent.
• Every principal that employs a registered lobbyist, and who lobbies for it.
• A link back to the official filing source on every profile.

To correct something, write to clerk@fiftydomes.com or claim the profile. Changes to an official filing must be made with the Department of State.
