Our Staff

Dan Griffiths

Years of experience: 35+


Dan graduated with Bachelors in Accounting from the University of Nebraska and has spent his entire career in the industry. He was a district manager and franchise director for a large accounting firm that allowed him to move throughout the midwest. In 1999 he was transferred to Sun Prairie, shortly after he took a tax manager position with a small firm allowing him to focus on individual clients, something the corporate world didn't often allow.


In 2013 Dan started SPTA where he wanted to focus on clients and create a close relationship with them that allows him to focus on their individual accounting needs.

Kayla Sanborn

Years of experience: 6+


Kayla graduated in 2011 with a double Bachelors in Accounting and Marketing. She specializes in small businesses, whether helping them start out or maintaining accurate accounting to keep up with the current tax laws. She started with SPTA shortly after it began and became a partner in January 2017.


Kayla and her husband own a successful painting company with several employees, as well as rental properties, so she knows first hand the difficulties and time it takes to run a business.
