Mental illness may be caused by a number of factors. Some people define mental illness as a chemical imbalance, while others believe it is due to some conflict, crisis, stress or trauma the individual is experiencing. If you, or someone you know, has some impairment in their normal thinking, emotional, or behavioral functioning, it is important that professional help is sought. Medication management, in addition to counseling, is usually the most effective treatment. Our medical team at T. W. Ponessa consists of experienced psychiatrists and psychiatric nurses. Our goal is to help bring you, or someone you know, back into the swing of life.
