"Dr. Farnham sat with me for over two hours going over every single detail about starting methadone treatment as well as other options, like microdosing with Suboxone and eventually switching to the Sublocade shot which has been proved to be life changing. Although the doctor was straight up honest when he said he hasnt performed the shot in over a year, I am still going to put my trust in his expertise and do the shot with him. He is one of the most progressive doctors Ive ever met. Although he is quirky and hums to himself (kind of annoying) he has given me really good information about Sublocade, Suboxone, and methadone. I have been struggling with opiod addiction (6 years - fentanyl) and I am a chronic relapser. If I get the Sublocade shot I hope to change my life around. I highly recommend Farnham. "
