About Joseph Yi, MD

Dr Joseph Yi is a Board Certified Addiction Psychiatrist who specializes in Holistic Psychiatry and Detoxification. After graduation from UMDNJ Robert Wood Johnson medical school, Dr Yi went on to do his psychiatry residency at Cooper University Hospital. It was at the heart of Camden, NJ where Dr Yi learned to treat some of the most challenging cases of psychiatric, addiction and detox patients. As a resident physician, Dr Yi had the privilege of apprenticeship under NY Times best-selling author, Joel Fuhrman MD, on nutritional therapy for mental health treatment. After graduating as Chief Resident of psychiatry at Cooper hospital, Dr Yi followed his passion for addiction medicine and has worked at dual diagnosis facilities (mental health and substance abuse) including Hampton Behavioral Health Center, Fairmount Behavioral Health, and Today Incorporated.

Since starting his solo private practice in 2009, Dr Yi has helped patients throughout Bucks County overcome their dependency to opiates, alcohol, and other substances through his Modern Detox Program . The program provides a personally individualized tapering plan on an outpatient basis, as an alternative to going into an inpatient facility for treatment.

In addition to conservative medication management, Dr Yi utilizes a more Holistic approach towards helping improve patients’ overall behavioral wellness by integrating the following as part of his treatment plans:

  • motivational counseling
  • nutritional therapy
  • exercise science
  • yoga
  • spirituality

Modern Behavioral is the group practice expansion and growth of Dr Yi’s original program. By creating a team of health professionals incorporating a Holistic approach to addictions and behavioral health treatment, the group is dedicated to offering the best quality of care while serving Bucks County – one patient at a time.
