Throughout his career, during those years Matt worked primarily on corporate-based expansions and local community developments. Upon his return to the east coast, where Matt was born and raised on Long Island, New York he set his sights on achieving his degree in business administration. This milestone in Matts life was successfully completed back in 2016, accompanied by a high honors accreditation from his alma mater.
By combining his passion for helping those battling with addiction & his expertise in the business world Matt has found his true fulfillment in life. As he has said many times, “the joy of being able to watch the lights come on for someone who has been stuck in the darkness for so long, through the amazing services we can provide to them are the priceless gifts of my career.”
Before joining The Freedom Center family, Matt built up and operated a small family owned outpatient treatment center in his direct community of Frederick, Maryland. During his tenure at that facility, he was able to interact directly with the clients and clinical staff giving Matt the unique ability to formulate a cohesively administered yet individualized protocol for addictions treatment. The idea of meeting the client where they are at and helping to guide them on the journey of recovery & set them onto the road of life is a process that Matt is passionate about. He believes that no addict ever needs to feel hopeless or lost, because we are here to show them that the light has existed within themselves all along. This approach to recovery work has enabled Matt to be a perfect addition to our team here at The Freedom Center. We look forward to working with him on battling the epidemic of addiction as well as breaking through the stigmas attached to it.
