P.T. from Katie helped me a lot and I am able to do more things for longer periods of time. One of the most valuable aspects of treatment was learning ways to control the pain. One thing that sets you apart from others is the attention to my specific issues and the attention to a holistic treatment.

Beatriz F.  (Patient)

Katelyn was great to work with while I learned how to expand my range of motion with neck and shoulders. She took the time needed to explain the exercises. She also provided very useful information and materials to assist me now that I have been diagnosed with osteoporosis.

3) I came to ARTS on the recommendation of my rheumatologist for my arthritis; in particular my right hip pain. As I moved from eval to treatment and home exercises, Katelyn always met me where I was. As I noted my progress, and learned about my body, she was “with me” all the way. Together, we saw progress and what needed more work. I was always supported and encouraged in my P.T. She and all the staff are warm and friendly. I received very useful instructions also from Darcy, Kwesi and Brendan. And I heard realistic info and nothing ‘sugar-coated’. Thank you all!

pt-matt-2016Matthew Morici, PT, DPT, Cert. MDT

Matthew Morici graduated from Sacred Heart University with a Bachelor of Science degree in Exercise Science in 2007. He was then admitted to the Doctorate in Physical Therapy (DPT) program at Sacred Heart, graduating in 2010. Matt began his career as a traveling physical therapist for two years where he worked in various clinical settings in Texas, Arizona, Florida and Virginia. While on the road, Matt was able to get sound experience in orthopedic and neurological outpatient clinics, skilled nursing facilities and acute care hospitals. He has since settled in the DC Metro area and became a full-time employee of Arthritis and Rheumatism Associates (ARA) in January of 2013.

Matt employs a variety of manual therapy techniques and therapeutic exercise in his physical therapy practice. In December of 2019, after extensive study, Matt became credentialed in the McKenzie Method of Mechanical Diagnosis and Therapy, a structured assessment method to diagnose and treat orthopedic conditions. Using McKenzie Method principles, Matt assists his patients in achieving rapid and long-lasting results and optimal physical therapy outcomes by using simple movements of the body and without developing dependency on the clinician. Matt’s main objective with each patient is to form a strategic alliance and provide the best possible care and guidance while encouraging the patient to become as independent as possible in the treatment and management of their condition and in preventing future recurrences throughout their lifetime.

At 73, my upper neck began to tighten up and I had some difficulty turning sideways and then one weekend the muscles greatly tensed up and it was very difficult to find a position to sleep. But thanks to Matt at ARA, I learned what was happening with the muscles, tendons, and joints and with exercises for neck, I’ve successfully found how to decrease pain and gain flexibility. The knowledge gained and exercises learned made the days and nights comfortable.

H.J.W  (Patient)

I have had hip, shoulder and back pain chronically for almost five years. ARTS, Matt especially have helped me stop being controlled by my disease / injuries and take control of my health again. I am able to complete all daily activities without difficulty.

Amara  (Patient)

Matt is my safety net and ergonomics guru. His matter-of-fact approach and emphasis on body mechanics helps me see the path and tricks I need to get stronger and stay stronger. No cheats, no shortcuts – just a path to a pain-free day. I appreciate it great! The rest of the staff is just as friendly and helpful.

Mike G.  (Patient)

After being hospitalized and some issues with my shoulder, which became worse as time went by the pain became worse.   And very limited mobility affected my daily life.  Working with Matt has had astonishing results, but knowing I will never be 100% the same.  The increased mobility has enabled me to a satisfactory life style again.  Matt provided me the motivation to keep improving. He was very professional and very organized.  The most valuable aspect in getting therapy here was “getting back into the saddle” after feeling somewhat hopeless. Thanks

Christine G (Patient)

After two total knee replacements, osteoarthritis treatment by Dr. Diamond, I had physical therapy with Matt.  Therapy with Matt was as good as it gets! He taught me techniques to help recover and motivate me to push on.  This was a great team, very competent combined with excellent physical interaction.  I am finally fixed!
