Thank you for your question.
Although, seizure control is often difficult, it sounds like you have a more important issue - lack of trust in your doctor. Certainly, you should feel comfortable with your doctor. The Cleveland Clinic has an excellent epilepsy group. Remember, your current doctor knows your son's history better, and your new doctor will have to repeat the history and maybe some tests before formulating his/her impression. But if you're not comfortable with your doctor, these are minor issues.
There are several epilepsy doctors who could be of use. I don't know their availability, but call 1-800-CCF-CARE and ask for an appointment - tell your son's age and other history. They'll be able to give you the earliest appointment.
As always, this should be used for informative purposes and does not substitute for seeing a doctor for therapeutic or diagnostic reasons
