Donald Duncan


After a successful career at Northern Trust Company, Don utilized his knowledge and experience to start D3 Financial Counselors in 1997. Don pursued this career change so that D3 Financial Counselors could concentrate on helping individuals rather than institutions. Our focus at D3 is to help people achieve their goals, utilizing best practices in financial planning, risk-controlled investment management and after tax wealth maximization strategies. Simply put, we help people organize, prioritize and optimize their financial lives. As independent, fee only, fiduciary financial advisors with offices in Chicago and the Western Suburbs, we serve our clients by providing Integrity, Trust, Wisdom and Confidence.
