Meet Diana Halenz, CPA, MT

Diana spent nearly 20 years of her career with Deloitte prior to starting her self-named CPA firm licensed in Florida and doing business as Deep Dive Financial.  After the Tax Cuts and Jobs Act was passed, Diana completed a Master of Taxation program at Villanova University to sharpen and freshen her tax knowledge.

Deep Dive Financial was named to reflect our love of details - from going deep into financials to identifying tax optimization strategies for our clients’ businesses.
