New Book Release: Your Character Is Your Culture: Lessons From UnitedHealth Group’s Transformational Journey

By Dave Sparkman Andersen Alumnus LinkedIn

There is a frustrating reality that needs to be realized: why do most attempts at culture change fail? Too often, they are treated as "outside-in" HR or marketing initiatives—relying on creative slogans, top-down mandates, and compliance training. They skip the hard part of transformation, opting for flavor-of-the-month programs instead of building something that actually sticks.

It is the same pattern I watched play out over a multi-decade corporate career. Drawing on the successful, historic inside-out transformation at UnitedHealth Group, I submit that sustainable change only happens when individuals personally invest in company values and change how they think and work every day.

In my book, Your Character Is Your Culture: Lessons From UnitedHealth Group’s Transformational Journey (May 2026), I suggest a different, proven path. Executives, managers, and HR professionals can use the powerful SPARK framework and 18 practical Trail Markers to serve as a field-tested roadmap to build a culture owned by the business and lived by the heart. No superficial slogans. No temporary initiatives. Just a clear, disciplined plan that delivers proven, sustainable results.

As Dr. Larry Senn (another former Andersen partner), "The Father of Corporate Culture," notes: "The results chronicled in this book, both tangible and intangible, are remarkable and well worth pursuing."

For any leader serious about moving past corporate compliance and building a true, values-driven movement, this book provides the exact blueprint.

Your Character Is Your Culture is available on Amazon, Barnes & Noble, and SparkYourCulture.com.
