Kolmac Philadelphia: outpatient addiction treatment in the heart of the city

Kolmac Integrated Behavioral Health has been providing evidence-based outpatient addiction treatment since 1973, and our Philadelphia location brings that same standard of care to the heart of the city.  

Located in Rittenhouse Square, we offer intensive outpatient programs, virtual detox, and medication-assisted treatment for adults ready to address substance use without stepping away from their daily lives. 

Philadelphia and the surrounding region have been significantly affected by the rise in drug overdoses in recent years. According to the CDC’s latest Pennsylvania drug overdose data, overdose deaths remain a serious and ongoing public health crisis across the state.  

Kolmac is committed to being part of the solution — offering accessible, flexible care that meets people where they are and gets them into treatment fast. Most patients can start within one business day of their first call.
