Dr. Mullen specializes in the multifaceted treatment of depression and other emotional disorders. He teaches that medical, spiritual and personality issues contribute to mental health conditions and must be individually addressed.

Dr. Mullen's practice is in Burlington, Ontario. He writes and lectures internationally on how medical treatment can be successfully combined with emotional and spiritual healing to break the chains of emotional and mental bondage.

A graduate of the University of Toronto, Dr. Mullen found that his family medical practice brought him into contact with hundreds of patients who suffered from anxiety disorders, emotional problems, depression, attention deficit disorders and other mental health issues. He began to focus on this area of medicine in 1984 and now treats only mood disorders at the Bayridge Family Centre in Burlington, Ontario, Canada.

Dr. Mullen has also written a number of books and videos which are available at seminars or through this website.
