I have found Dr. Davis to be the most knowledgeable psychiatrist about medications that would effectively treat my conditions. In my experience with her, she has given me sound medical and psychological treatment, that has been backed by two psychiatric hospitals. I have never met a Board Certified Psychiatrist with the extensive education and expertise that she has to both use medication and therapy in her practice. I have been to psychologists, and none match her quality of therapy. The best!!
