I provide a wide variety of services including consulting, setup and training services, and full service bookkeeping.

Where I Do It

I provide services from my home office in Glenview, IL or onsite to ChicagoLand businesses.  However technology available today allows me to provide the same quality services to businesses that wish to retain my services, but are not located nearby.  Its a lot easier than you may think.  I recently completed a multi-year project working seamlessly with a Real Estate Development Company in Mexico.

How I Do It

By taking the time to fully understand where your business is today, and where you may be headed in the future, it allows me to customize my services to make sure your current and future needs are covered.  I offer a complimentary consultation to discuss your needs, my services and to see if we are a good fit for each other.  No Cost, No Obligation.  Should you decide to contract my services you will find my rates very competitive.
