Why addiction medicine? “Transitioning to addiction medicine was easy in that during my residency training I would come across folks whose lives have been literally destroyed by prescription and illicit opioid use and they don't know where or how to get help. I thought I’d offer to help with their treatment and recovery journey. I also wanted to be part of a growing field with an array of talented providers providing care to our vulnerable population."

Why Geisinger? "Geisinger's Addiction Medicine Fellowship has a strong reputation for being a leader in providing care for substance use disorder and providing excellent training to addiction specialists. I knew I would receive good training which would enhance my skills and knowledge in the field of addiction."
