Being a CPA means constantly encountering new opportunities. Where some people might see a problem, Mark sees an opportunity get to the root of the issue and come up with a creative solution or process that will optimize his client’s results. Mark’s goal at the end of every project is a happy client who has the tools and information they need to take on their next challenge.

Mark relies on his broad background in public accounting and private industry to help him meet this goal. He has performed a variety of tax compliance and planning projects, including estate planning, for clients that have ranged from individuals with a small rental real estate portfolio, to businesses with sales of several hundred million dollars. In addition, Mark has structured business entities, created and installed accounting and information systems, obtained financing, and managed the attest process, both as auditor and client. In his over 30 years as a CPA, Mark has gained experience and expertise in diverse industries including real estate development, construction, property management, manufacturing, healthcare, and automotive dealership accounting.
