Medical Director,
Middlesex Recovery

Brian W. O’Connor, M.D., is the National Medical Director at Middlesex Recovery. Dr. O’Connor began practicing medicine in private practice in 1991, initially specializing in obstetrics and gynecology. He spent 20 years caring for patients in Melrose, Massachussets. In 2005, driven by his experience with an adult child struggling with substance use disorder and a surge of pregnant women with substance use disorder seeking treatment, Dr. O’Connor began to explore addiction medicine.  

Initially, he treated only pregnant patients. With the growing opioid epidemic, Dr. O’Connor founded Middlesex Recovery, an addiction medicine practice, in June 2010. He now specializes in the care of opioid dependence, with additional interests in alcohol misuse disorders, underserved populations, and the corrections community. 

Dr. O’Connor is board-certified in obstetrics and gynecology and addiction medicine. He holds degrees from Boston College and Georgetown University.
