“As a healthcare provider and a small business owner, Kathleen came to my rescue in early 2025 and cleaned up a royal mess that was left by my last bookkeeper. Not only is she the best at what she does, but she has patience, skills, and a great sense of humor. Kathleen has not only helped me clean up the mess, but keeps my books current and doesn’t miss a penny. Even my accountant was so happy that I hired her! If you have a small business, you know you’ve got 1 million things on your plate. Let Kathleen take some of that off so you can actually have a life after work.”

Goes Above and Beyond
“Kathleen O’Brien is the bookkeeper for our nonprofit. She is a pleasure to work with at all levels. She has a deep understanding of bookkeeping and accounting and makes excellent, pertinent recommendations for our organization. Kathleen is responsive and when she is unfamiliar with a request, she researches until we have a solution. She has proactively worked with our tax accountant to ensure our books will be best prepared for tax season. We keep in touch regularly and she provides reporting after she closes out each month and before our quarterly board meetings. Kathleen has gone above and beyond on tasks that support our nonprofit.”
