Greg joined the firm in 2009 as a result of an acquisition of a local CPA practice.  He works with small and mid-sized privately held companies, providing audited and reviewed financial statements.  Additionally, he provides tax planning, compliance, and consulting services to businesses and high net worth individuals.
