About TaxWorks

We provide client tax & financial services through quality, professionalism,
trust and collaboration.

Taxworks was founded in 2001 by Boulder native and CU Business graduate, Mark Sehnert. During his life, Mark found joy in giving back to the community. He was very involved in Alcoholics Anonymous, helping others move through the program steps. His dedication and altruistic tendencies were present both in his community work as well as his business. He was deeply loved and still remembered fondly for the lives he touched today.

After Mark’s sudden passing in 2008, the business was sold to Anthony “Tony” Adley. Tony had over 30 years of business experience, including executive positions in finance at an engineering and contracting firm. Tony held ownership of Taxworks from 2008 to 2019 until he retired and entrusted the business to its current owner R. Cole Frye, CPA.

Cole is committed to adhering to the same quality standards set forth by both Mark and Tony. Cole has carried on in the tradition of community work set forth by Mark through programs that relate to mental health, music, and financial education.

Cole believes in being relationship-oriented in practice, instead of transactional.
His main focus with his clients is to be able to help “move the needle.”
