Non compete agreements vary from state to state and are generally not favored by courts. Although in many states (such as Kansas), they can be enforceable. In order to fully appreciate the extent of your particular non-compete, you should discuss this with an employment lawyer licensed in Kansas.
Generally speaking however, in states where employment agreements are enforceable, they have to be reasonable in duration and scope and must be a protectable interest of the employer. Simply put, most courts recognize that a business cannot prevent an employee from working in his or her chosen field - simply because they came to work for this particular employer. If that were the case, then you would be forced to move every time you changed jobs.
However, they may be able to keep you from engaging in certain business. For example - a RN in a stand alone dialysis clinic may be reasonably prohibited from working in another stand alone dialysis clinic, but not from working as an RN for another medical practice. This gets vague when the RN goes to work for a hospital in the dialysis department.
Anyhow, your local lawyer would be able to sit down with you and help you understand the strength of your own non-compete in light of your community and job description.
