Founder | Accountant

As the founder of Dio’s Financial Services it has been my life long dream to provide services and support to individuals and companies from corporations with large, complex portfolios to individuals simply looking to better organize their finances. I am currently working with companies ranging from $500,000 to $5 million in annual revenue. I help these companies to better understand and achieve their business financial goals. I am highly motivated and passionate about service and building strong business financial portfolios and working with business owners to create a financial process that will improve their business finances.

I received my BS in Finance from the University of Massachusetts Lowell and my Financial Accounting Certificate from Harvard Business School Online. I am a member of the Merrimack Valley Chamber of Commerce, Greater Boston Chamber of Commerce, and Member of the Association of Accountants and Financial Professionals in Business.

Hilary Marroquin

Accounting Assistant

I am currently an accounting student at the Isenberg School of Management at the University of Massachusetts in Amherst. I am a numbers gal, I chose accounting because it is the mother of numbers. Throughout my education at UMA, I have learned accounting concepts, financial modeling and business management skills. I enjoy working with businesses and helping them grow. My biggest goal is to graduate with an accounting major next spring and continue working in the accounting field, helping businesses reach their goal.
