Lucy Ryan is a QuickBooks ProAdvisor.  She completed the “Just Add One” Business Program facilitated by the Westchester-Putnam Workforce Development Board in 2016.

I have been a CPA in Ossining for 23 years. I find when working with Plus 1 Bookkeeping (Lucy), I get the books in a condition that allows me to prepare the tax returns with only year-end accounting adjustments needed. I find her to be detail oriented and she prepares your books as they were her own. She does professional and accurate work at a reasonable rate. I have recommended her to many clients and will continue to do so.


Chris Hale, Founder & President

Lucy Ryan is an incredible asset to any organization. Her experience, high aptitude, organizational skills and reliability make her the Total Package when it comes to Bookkeeping and more. 

At SunBlue Energy, we've been working with Lucy throughout 2017. She walked into a very difficult situation that required a tremendous amount of cleanup of the books. She methodically worked through the issues and now 6 months later, we are in a much better position. 

Thank you Lucy!


Trevor Tunnell, President

I have been working with Lucy for about a year now and couldn't be happier. She is very strong with QuickBooks and very diligent in her attention to detail. We have some unique needs with the number of properties we manage, each having a separate company, and Lucy is very adept at making sure all the books are correct and timely. If you have regular bookkeeping needs, Lucy is great, but when you have anything out of the ordinary, her talents really shine!
