We Foster Education

To say we are addicted to learning may be an understatement. Our founder, Jessica Rubenking is a perpetual student. Her mother calls her a “lifelong student” and when you work with her, you can tell. Her abilities are unmatched and her commitment to excellence is unwavering.


Why choose Us?

Running a business is very difficult for many reasons, some of which are financial limitations, time constraints (as there never seems to be enough hours in the day to get everything done), laws and regulations, marketing, etc. and all that before you can even open your doors! We are a small business serving other small (or big) business owners and managers by providing quality work with the quantitative costs involved with staffing administrative support.

Our Staff

Our expert, trained and professional staff will never let you down and will always be there to share your workload in the most efficient way possible. From bookkeeping, to secretarial, to training, we have what you are looking for…or possibly didn’t even know you needed!


Our motto

Our motto is simple yet profound: We take BUSY out of business. Let us take the workload so that you can get back to what matters most in your business: being profitable.

My business has been growing like crazy, so much so, that I was getting bogged down in my bookkeeping tasks. In order to track out progress, and measure our goals, I needed accurate up to date books. I can do the work, my assistant can do the work, but we do not have the time to do both sales and bookkeeping. I’m also a CPA, very picky about the quality of my books and needed to have someone that I was not only competent but one that I could trust. Jessica is BOTH!

Honestly, my systems are unique, and I dreaded having to train someone to do this for me. A few power sessions and she understood what I was trying to do and has kept my books in excellent shape. It’s great having another set of eyes on the books. Also she is making sure two of our reporting systems are tying together. For the first time ever, I feel like things are no longer falling through the cracks. I would recommend Jessica to anyone that needs to get your bookkeeping up to date, setup systems, and get your workflow straight. She helps you get things DONE!Carrie Kahn, Complete Business Group
