"John Hickey and DeNovo Tax & Advisors was recommended about four years ago and I will never look back.  John really listens and cares, and does a great job on my taxes both personally and for my business as an independent contractor.  I trust him completely, and have moved my investing into his care as well.  I've recommended John to many people, and will continue to do so.  John is a highly competent accountant, a truly nice person to work with, and the staff at DeNovo are always helpful and knowledgeable."

"John Hickey from De Novo Tax & Advisors has been helping our dental practices for over twenty years.  It has been just an outstanding and professional job with any tax, IRS paperwork, and any important applications and forms.  Extremely organized, always available, and quick to complete any necessary papers.  Thank you, John, for the great experience by keeping our business offices running so smoothly throughout the years."

Dr. Joseph M & Tatyana M, Dental

"I have been a customer of John Hickey since tax time, 2014.  I own a small landscape company.  John was a recommendation because the firm doing my taxes did not do business taxes.  He has been honest and straightforward with me.  Does a great job in a timely manner for my wife and I."
