Our Story

Dan Musick, CPA PLLC was originally founded in 1982 by Sam Cooper, CPA. Sam opened his office in a small building in San Marcos with nothing but a calculator and a chair. Sam owned and operated the Firm until 2004, expanding to Buda along the way. In 2004, Steve Cook, CPA purchased the San Marcos practice and the Firm became known as Cook & Associates. Under Steve’s management, the firm grew to include offices in Austin and San Antonio. In September of 2010, Dan Musick, CPA purchased the San Marcos practice and it became Dan Musick CPA PLLC. The Firm currently serves almost 400 clients across the state of Texas. We have come a long way from “a calculator and a chair” but we never forget that any success that we may achieve depends on our clients.

DMCPA offers a wide range of tax, bookkeeping and accounting, consulting, and payroll services. Through strategic alliances with business partners, we are also able to help our clients find help with financial planning, insurance, banking, and legal services. We believe that what sets DMCPA apart from our competition is our commitment to providing the client with someone who will be on their team and take an interest in their growth and success – as opposed to just being someone like the dentist who they see once a year only because they have to.
