Faculty: Philip Keddy

Philip Keddy, PhD

Adjunct Professor

San Francisco, Online

Dr. Keddy has been a licensed psychologist since 1985 and in full-time independent practice since 2001. Relevant to this course, he worked half-time from 1990 until 2001 in the outpatient alcohol and drug program at Kaiser Walnut Creek, supervising interns as well. While Kaiser was primarily group work, he has continued to work with people who have addiction problems on an individual basis in his independent practice. He works with a variety of people having a wide range of problems; addictions is a specialization. He also does personality testing, combining the results of psychological tests and interviews. He does alcohol and drug use assessments in custody cases and for other purposes as well.

Dr. Keddy was fortunate to receive training in motivational interviewing from Miller and his colleagues at the University of New Mexico, through visits to Albuquerque, telephone consultation, and their review of audiotapes he submitted.

A collaborative assessment case study he co-authored was accepted for publication in the Journal of Personality Assessment in 2010. He is also teaching Adult Assessment at the Wright Institute in Berkeley and has presented at national and international conferences on assessment topics in the last few years.
