Meet The Team

DeRosa Physical Therapy in Linwood, NJ is a trusted company with over 20 years of proven results. Since 2000, we’ve earned a positive reputation. Our first objective is to provide the patient with pain relief because we know alleviating the pain will allow the therapist to manually restore normal movement. Movement is followed by strengthening which is tailored to each individual patient. 

Here, you’ll experience a positive atmosphere when being treated. Let us motivate you during a difficult time because we care about your physical goals and your emotional well-being.

Joseph (Joe) DeRosa


Joe DeRosa is the president of DeRosa Physical Therapy. He attended Widener University and was accepted into the Physical Therapy Program as an early entrant. He received his Bachelor’s in Biology in 1997 and his Masters in Physical Therapy in 1999.

In 1999, Joe returned home to begin practicing physical therapy. After a year of outpatient practice, he decided to open up his own practice. The primary focus of the practice was to make people feel better.

Over the past 21 years, DeRosa PT has steadily grown because of the results seen in the community. The 2400-square-foot facility is fully staffed with three full-time therapists with a combined 55 years of experience.

Joe stays on the cutting edge of rehabilitation by attending classes and seminars throughout the year.
