Publicly Available Classes
We have been involved with training seminars for more than twenty years. More recently, we have begun offering to the public courses we developed in part for the needs of clients. These courses range from technology tips to applications such as Microsoft Office, QuickBooks, and others. In 2010, we began offering some of these training opportunities to CPAs in pursuit of continuing education. Please contact us for schedule and venues.
