Duncker Streett & Co. is a boutique investment advisory and portfolio management practice located in St. Louis, Missouri that provides investment management services to individuals, trusts, pension and profit-sharing plans, endowment funds, charitable trusts, corporations, and personal-holding companies. At Duncker Streett & Co., we recognize that no two investors are alike, so client assets are managed on a case-by-case basis with each portfolio built to reflect the distinct goals, objectives and interests of those who have entrusted us with their money.

In the 1960s, Donald Streett and Charles Duncker began working for the St Louis branch of Brown Brothers Harriman Trust Company. In 1990, the two purchased the local branch and founded Duncker Streett, a Registered Investment Advisor for institutions and high net worth individuals. Though the founders have departed, what remains is their commitment to client service, a fervent dedication to a thoughtful investment process and a clientele that dates as far back as four generations.
