02 / THE FOUNDER

The person
behind the
numbers.

Spencer founded Impact Tax and Advisory on a simple belief: the best advice starts with understanding the person behind the numbers. Too often, tax professionals focus on forms, deadlines, and compliance while missing the bigger picture.

His approach is different. Before discussing strategies or preparing returns, he takes the time to understand your needs, your business, your goals, and the challenges you face. It’s an approach that builds lasting relationships — and leads to the better outcomes you’re searching for.

Born in Wichita, Kansas, and a veteran of the U.S. military, Spencer is a CPA licensed in Colorado and Texas, with experience spanning public accounting, corporate tax, and private practice — including positions with PricewaterhouseCoopers and Ball Corporation.

Because good tax advice isn’t just about understanding the tax code and providing a solution — it’s about understanding the people, and providing a solution that matters to them.

in four moves.

Every engagement follows the same arc — and it starts by getting to know you, not your tax return.
