JOANNE PARKS, M.D.

Medical Director

Board Certified Psychiatrist

Psychotherapy, Psychopharmacology,

Expert Witness

Dr. Parks has been a psychiatrist in the Chicago area since 1993.  She treats people from all walks of life and with the full spectrum of psychiatric problems. She offers comprehensive psychiatric evaluations, expert second opinions and private consultation to individuals, other physicians and mental health providers, businesses and attorneys. She also provides ongoing psychotherapy and psychopharmacology services for men and women.


Dr. Parks completed her residency in adult psychiatry at The New York Hospital-Cornell Medical Center, Westchester Division and an additional fellowship in the treatment of trauma at Rush Presbyterian St. Luke’s Medical Center.

Dr. Parks has broad experience using a variety of different treatment modalities both for psychotherapy and psychopharmacology.  She believes that it is important to listen carefully and offer individualized care based on the patient’s specific problems, concerns, needs and preferences. This includes an interactive, practical, solution-focused approach to help clients resolve current problems. Sometimes unresolved issues from the past may cause unhealthy patterns in the present and interfere with your ability to live a fuller, more meaningful life. Or, those issues may create patterns that repeat themselves in unhealthy ways in your life. Some patients also enjoy exploratory therapy to promote personal growth, insight and self-awareness. When medication is advisable, Dr. Parks will explain the choices that are available and review the risks and benefits involved.  Dr. Parks will then answer any questions you may have. If you are receiving care from other medical and/or mental health providers, she will also communicate with them, with your permission, to collaborate in the coordination of care with the goal of enhancing the integration of your care. She would be happy to discuss your specific concerns and design a personalized care plan to meet your needs and help improve your life.
