Meet Our Executive Leadership Team.

Upon finishing college at the University of Utah in 1979, Peter Schorr accepted an entry-level position at a methadone clinic in New York City, where he diligently worked his way up to become CEO of West Midtown Medical Group, an addiction and infectious diseases treatment facility serving 1,000 patients every day.

Over the course of his career, Peter has held positions in all areas of the treatment industry, recognizing the urgent need for high-quality residential services for substance use and mental health. In 2008, Peter took over the reins at a struggling Pennsylvania substance use facility, turning it around to become an advanced, reputable provider once again.

This success inspired Peter to open his own facility — Retreat at Lancaster County, PA — in 2011, a 120-bed residential drug and alcohol treatment center providing all levels of care.

The revolutionary Retreat model gave rise to a large national network of facilities, starting with the single Pennsylvania site and growing into a family of locations in Florida and Connecticut, as well.

When he isn’t working, Peter enjoys recreational time with family and a number of outdoor sports, including skiing, snowboarding with his son, and riding motorcycles. He is also a dedicated musician with a passion for singing, songwriting, and playing guitar.
