He then joined the firm of Miller Wagner, where he earned his CPA certification in 1997. Then, after furthering his education and earning a Master’s degree in Taxation in 2001, he decided to step out on his own and build an enduring CPA practice focused on small businesses, their owners and the growing community of Maricopa.
