Peter Mahan
Director of Business Development
My name is Peter Mahan and I was born in Danville, PA. When I was 7 years old I moved to Marlton, NJ with my father, mother, and brother. I was fortunate enough to attend all private school from kindergarten all the way through freshman year of high school. The household I grew up in was extremely loving and caring so I was given pretty much every opportunity to succeed from a young age.
When I was 12 years old my father was diagnosed with pancreatic cancer and passed away shortly after. Watching my father deteriorate just within a 6 month period was extremely devastating and traumatic for my family and I to go through. My father was an active member in Alcoholics Anonymous and passed away with 20 years of sobriety. Throughout my childhood I was blessed enough to grow up in a household that didn’t contain any drugs or alcohol in it.
Shortly after my father’s death I was involved in an extremely bad bike accident which almost led to me getting my leg amputated. After numerous surgeries and skin graphs the doctors were able to reconstruct my leg. Those surgeries led to me getting prescribed pain medications from an early age which is where my addiction all began. At the age of 13 I began to experiment with marijuana and alcohol.
Recreational drug use led to a full blown opiate addiction by the age of 16 which caused me to be the worst version of myself for the next 10 years. After 23 treatment stays and just a few incarcerations later I decided it was time for a change. In 2020 I took a leap of faith and God granted me the willingness to change my life and I haven’t looked back since. I firmly believe the only reason why I continue to stay sober today is because I simply help others and give back what was so freely given to me.
I’m blessed enough to say working in behavioral health isn’t something I consider as my “job” because I can proudly say I love what I do. Over the last 4 years I’ve poured my blood sweat and tears into being a behavioral health technician, admissions coordinator, business development rep/director and it has all come back to me full circle. At Diamond Behavioral Health we’re here to help all of those struggling with addiction and mental health concerns on a greater scale. I look forward to watching millions of individuals transform their lives into something that they never thought was possible like mine.
