Dr. Deringer will begin the evaluation process with a thorough one-hour session in which we will discuss your current symptoms, your prior treatment history, your medical history, and your goals for treatment.  At the end of that session, she will begin to formulate her diagnostic impression and treatment recommendations.  Sometimes, the evaluation process may require more than one session, and it may be helpful for Dr. Deringer to gather information, with your permission, from prior treatment or to collaborate with your therapist if you have one.  Dr. Deringer will work with you on a medication treatment plan, if clinically indicated, to help you manage your symptoms and achieve your treatment goals.
