Headquartered in Indiana, Pennsylvania, Stewart Capital Advisors, LLC (SCA) is a wholly-owned subsidiary of S&T Bank and is an SEC registered investment advisory firm. SCA was officially formed in September 2005, emerging from the investment team at S&T Wealth Management.

In that capacity, SCA managed portfolios of high net worth clients, trusts, and institutions. SCA continues to manage such portfolios as subadvisor to S&T Wealth Management. The current investment style and process dates back to 2001, when Malcolm Polley assumed leadership of the investment team.

Since 2005, the firm has expanded its institutional business. SCA currently manages assets for public funds, ERISA plans, corporations, endowments, and other subadvised accounts.
