John O’Brien is a distinguished former American soccer player whose career is marked by significant achievements both in the United States and Europe. He began his professional journey at Ajax Amsterdam, where he signed an amateur contract at just 17 years old. O’Brien quickly made a name for himself, becoming a regular starter and contributing to Ajax’s success in the Eredivisie, winning titles in 2002 and 2004. His versatility allowed him to excel in various positions, particularly as a defensive midfielder, where he showcased his technical skills and tactical awareness.

O’Brien’s international career with the United States national team further solidified his reputation. He earned his first cap in 1998 and played a pivotal role in the 2002 FIFA World Cup, where he scored the opening goal against Portugal and assisted in another crucial goal. His performance during the tournament was instrumental in leading the U.S. to the quarterfinals, making him one of the first Americans to achieve such a feat in the Champions League. Despite facing chronic injuries, O’Brien’s determination and skill earned him a spot on the roster for the 2006 World Cup.

After his time at Ajax, O’Brien had a brief stint with ADO Den Haag before returning to the MLS with Chivas USA. Unfortunately, injuries limited his playing time, and he officially announced his retirement from professional soccer in 2008. Following his retirement, O’Brien pursued a doctorate in clinical psychology, demonstrating his commitment to personal growth and helping others.

Today, Dr. John O’Brien operates two practices, one focusing on mental health counseling and the other specializing in sports psychology. His journey from a promising soccer player to a respected psychologist highlights his resilience and dedication to making a positive impact in the lives of others, both on and off the field.
