Matthew Mackowiak
The register gives a lobbyist a separate record at each firm. This person is very likely also listed as Matthew Mackowiak (Consol Energy, Inc), with the same distinctive name at back-to-back firms. The register itself does not confirm these are one person.
Lobby filings counts every filing that names this lobbyist, amendments included. Contributions come from the twice-yearly LD-203 reports, counting the current version of each report once.
