Your feedback matters

  • I met Kathy Gellis many years ago at a workshop, and it's been one of the best things that have happened to me. My office was stacked with piles and piles of paperwork. I was desperate. I had so much to do that I couldn't get one thing done. My stress level was to the roof, and then I met Kathy. She quickly processed the paperwork, and paid all the outstanding bills, applied for refunds I was owed, balanced my personal and business checking accounts, handled my taxes, she took over my entire business and personal finances. Kathy has been there for me in business, as well as a friend. She is honest, capable, and efficient at what she does. I would recommend her to anyone without a shadow of a doubt.

  • Kathy Gellis of Gellis Consulting, has been with my business for several years doing an outstanding job with my bookkeeping. She is honest , has integrity and has brought several areas of my business together. I am recommending Gellis Consulting for your bookkeeping and accounting needs. Her office staff is very helpful and very professional .

  • Kathy and her colleagues have been absolutely instrumental in the successful operation of our association. They have made my “volunteer” position actually enjoyable, leaving little about which I need to worry. Gellis Consulting is as professional, trustworthy and reliable an organization as I have ever experienced. I also chair my condo association back in Boston and only wish I had Kathy to work with there as well. And in a final tribute, Kathy has become family to us.

  • We are a small business and hired Gellis Consulting in 2015 to handle payroll, monthly and year-end tax filings through Quickbooks.  This has freed up time for us to concentrate on the production of getting work out the door.  Knowing we hired a qualified and experienced person to file all the necessary paperwork helps to reduce the stress tremendously.   Kathy and her staff are very professional and have been a pleasure to work with over the years.  I would highly recommend her professional services.

  • "As a company, having a person or company that you can trust with your inner workings and financial status is arduous and difficult. Gellis Consulting took charge and minimized any apprehension we had coming into our initial meeting. Since that time, Kathy has shown immense patience and impressive attention to detail and accuracy. We recommend Gellis Consulting for any bookkeeping needs!"

    Enrique Sasson – Lionheart Printers

  • "I’ve owned my businesses since 2001 and was pretty savvy with Quickbooks.  My company had experienced a little bit of growth and it was becoming more difficult to keep up.  I was given the contact information for Gellis Consulting and have never have looked back.  Any and all issues are solved very quickly and perfectly, which makes it much easier to manage the day to day issues that arise.  Extremely professional and pleasant to work with."

  • "Kathy Gellis has a thorough understanding of the full capabilities of QuickBooks software which far exceeds that of other bookkeepers I have worked with. She designed an accounting system tailored to the specific programs and management information needs of our not-for-profit. As a result, our officers and directors have financial information truly helpful to decision making. She is a pleasure to work with."

    Eric Rydstrom

    — Treasurer, Navy League of the United States, Palm Beach Council, Inc.

  • "We're excited to tell you how grateful we are for your assistance. Our company is growing quite rapidly, much of it due to the fact that you've taken the burden of keeping a watchful eye over our books while we go about doing what we do successfully: adding new business.

    On a second note, helping our Mom with her checkbook and savings account, has given her more confidence that she has money in the bank, and she no longer has sleepless nights wondering whether she can get by.

    Don't know what we'd do without you. Well, maybe we do. It would involve counting on our fingers and toes!!LOL!!"

  • The value of time!!! Publishing , editing, printing, delivering, selling ad space for Coffee News is a full time effort. Taking the time to learn Quick Books , make entries, reconcile bank statements, prepare reports for my accountant is not something I have time to do accurately. I needed to find someone I could trust, have minimal communication, and provide me with timely reports. Gellis Consulting has been my invaluable resource to provide me with support I need in this area of my business. Kathy Gellis has also provided insight into the approach a small business should take regarding their overall record keeping as well as suggestions to improve overall account and sales management. Consider Gellis Consulting for your business or personal financial records keeping.
