Who we are
At Hilltop CPA, our foundation is built on the deep technical expertise and executive-level governance that you typically only find at the world's largest professional services organizations.
Our leadership team is comprised of CPAs who spent eight or more years managing complex tax compliance and advisory engagements for Fortune 500 companies and global enterprises at a Big 4 firm. That experience is the Hilltop CPA standard.
