Not only does he run his own independent psychology practice in Columbus, Ohio, but he is also the Psychological Consultant to the Ohio Division of Disability Determination, the President of PsychContinuingEd.com, LLC, and the Public Education Coordinator in Ohio for the APA. His vast and wide-ranging experiences give him plenty of credibility in the field and he has plenty of knowledge on the profession and the industry in general to share. He is not the most active or diverse Twitter user, but he does use it pretty consistently and usually shares worthwhile reads or thoughts, making him a worthwhile follow for people interested in psychology.
