Az Capitol Times . . . Don Isaacson recognized as Best Lobbyist and Toughest Lobbyist to Go Up Against

Don Isaacson is a nine-time winner of the Best Lobbyist award presented annually by the Arizona Capitol Times as well as additional awards, including best Lobbying Firm.

“The long-running joke at the Capitol is that the Best Lobbyist category should be renamed the ‘Don Isaacson Best Lobbyist Award.’  The mark of a solid lobbyist is honest representation, and that’s especially true in a world where one’s word is the currency.  At the state Capitol, Isaacson’s work stands out, and colleagues regard him as the consummate professional, the lobbyist who understands that a good lobbyist fights the good fight for his clients but doesn’t seek to tear down his opponents. That helps explain why Isaacson has won this award a record eight times...The firm, founded by Don Isaacson nearly four decades ago, is considered among the best of the best.  The secret to the firm’s success is no secret at all – hard work, passion, honesty and integrity.” Arizona Capitol Times. 6/26/18

In past years, the firm also has been recognized as being among the Top 25 Policymakers of Arizona, appearing along with the Governor and other key elected officials.  The Arizona Capitol Times is the leading source of political news from the State Capitol.
