Pittsburgh Accounting firm names new managing partner

Sisterson & Co. LLP said Bradley P. Lusk will become its managing partner as of Jan. 1. He will succeed William E. Troup, who has served in that position with the Downtown certified public accounting and consulting firm since 1997.

Troup announced his retirement and will continue until then as assurance services partner. Lusk joined Sisterson in 1991, after six years at a national CPA firm, and currently heads the growing not-for-profit practice area.
