Our Past, Present & Future

The Story Of How We Got Here

In 1988, Donald P. Kelly, a successful Chicago businessman, founded Whitnell along with two experienced investment professionals – Bill White and Mike Brunell. From the merger of their two last names, the Whitnell company name was born. One of the hallmarks of Don Kelly, as an executive, was leadership. He lead by example and hired great people who were considered experts in their individual disciplines. He gave them autonomy to make decisions and run their divisions as they saw fit. Bill White epitomized this philosophy and built the foundation on which Whitnell stands.

Business Owners, Executives, Affluent Families

Our Clients' Goals and Concerns

Why They Work Hard & Take Risks

Families like this share certain goals and concerns. They put family first and want their wealth to be available to support the ones they love. This is their top concern. A loss of wealth is equivalent to a loss in their ability to care for their family.


These individuals want their wealth to grow. Many of our clients have worked very hard for their wealth and now want it to work for them. However, their desire to grow their wealth almost never supersedes their desire to preserve their wealth. They want to be intelligent and thoughtful about the level of risk they entertain, taking risk that results in positive gains.

Our Clients' Values

What Matters Deeply To Them

Our clients value comfort. It is important to them to be comfortable with a financial advisor. They often choose to have a financial advisor build relationships with numerous family members, not just a primary patriarch or matriarch who controls wealth. They want to make sure spouses and children know their financial advisor and are being advised on the key issues that impact their family.
