Hi, I am Joseph N. O'Donnell, PhD. I have been treating stress disorders and anxiety for over thirty years. My doctoral dissertation at Northwestern University focused on social anxiety. Since then as a Marine veteran, I have worked with veterans with post-traumatic stress disorder, phobias, and other adjustment disorders linked to war experiences. I had also worked on a woman's program at Woodland Hospital (Alexian Brothers) dealing with PTSD issues. Anxiety is consistently comorbid with addictive disorders. I have a long history of working with addiction as well.
