AANA is pleased to welcome Dennis Siena, CPA as the new Vice President of Finance, joining the full-time AANA Staff of 19 working professionals.

Dennis brings with him over 19 years of financial and accounting experience to AANA. After completing his Bachelor of Science degree in Accountancy at Northern Illinois University and earning his Certified Public Accountant (CPA) license, Dennis went on to serve accounting positions at a variety of healthcare-focused organizations.

Dennis’s passion for accountancy peaked at a very young age; between being raised by accountant parents and assisting his father’s accounting and tax practice, earning a degree in accountancy was only a matter of time.

In his spare time, Dennis keeps up with his continuing financial education through his membership with the Illinois CPA Society. He can also be found giving back to his community through his position as Deputy Sheriff Lieutenant for the Lake County Auxiliary, where he’s able to assist the highway patrol division of the Lake County Sheriff’s Office. Through this position Dennis found a tight-knit community he admires, similar to that of AANA’s.

Dennis is excited to share his analytical skills and vast knowledge in accountancy to build upon the financial processes of AANA while also contributing to providing additional AANA Member value. is made possible by displaying online advertisements to our visitors.
