About Dorsey and Semrau

Dorsey and Semrau has an 80 year history of providing exceptional legal counsel to municipalities. The firm began in 1931 with David Young III, who later was a N.J. Senator from 1947-1953.

In 1976, Senator Young approached John Dorsey to purchase the practice. John was a neighbor of Senator Young in Towaco. After taking over the practice, John served in both houses of the New Jersey Legislature from 1976 to 1994, serving in the New Jersey General Assembly from 1976 to 1978 and in the New Jersey Senate (Minority Leader) from 1978 to 1994.

When Senator Dorsey acquired the practice, the firm represented Hanover Township, Butler, and Montville Township. Soon after, additional municipalities named Senator Dorsey as its municipal counsel. In addition, Mr. Dorsey was named as General Counsel for the Morris Joint Insurance Fund (MJIF) in 1988 and the Municipal Excess Liability Joint Insurance Fund (MEL) in 1994.

In 2004, the municipal law practice continued to grow with the addition of Fred Semrau. Sadly, John Dorsey passed away in December of 2018 but his legacy lives on as the firm now has seven experienced attorneys who specialize in all phases and aspects of municipal law.
