Preparing personal and corporate income taxes since 1972. Entrepreneur, hard-working, enthusiastic, caring, devoted, mentor and a friend to all…

These are only a few of the adjectives that describe Aldo Costantino, a major force behind the Personal and Corporate Tax Preparation Industry scene for over 40 years. Aldo has been a business owner since 1972 starting with his own Accounting and Bookkeeping practice, providing services to small businesses such as contractors and retailers.

In 1976, Aldo purchased a small travel agency. Aldo sold his bookkeeping practice in 1984 to focus on his growing Travel Agency but continued to prepare personal and corporate income taxes every year. At that time the travel agency had a revenue of $290,000 annually. The agency grew to be the fourth largest National Corporate Travel Company with an annual revenue of 80 million in 1996.

In 1997, Aldo became a Financial Analyst with a large Import & Export company with an annual revenue of over $700 million. His role included budgeting, reporting, reconciliations, processing payroll for over 200 employees, analyzing the profitability of goods for sale and managing the customer volume sales rebate program. While working as a Financial Analyst, Aldo continued preparing income taxes for his long-time clients year after year.
