Rebecca has clinical experience in orthopedics, sports medicine, neurology and geriatrics. She has been a professional dancer for 13 years and was also a fitness instructor, choreographer, and master trainer at the YMCA for 19 years.


Suddenly, during playing tennis, I could barely walk as the pain was so sever in my right side from my hip to my knee. My doctor, David Wolfe, said I had an inflammation of the bursa sac (bursitis) and recommended physical therapy at one of his centers. Luckily, I chose Shady Grove, as it had free parking and the staff (all of them) couldn’t have been nicer. My therapists, Josh and Rebecca were very professional and friendly at the same time. Rebecca was extremely helpful when I explained how the pain was severe when I first awakened and lessened during the day. She suggested doing certain exercises while still in bed and slowly getting up so that the blood would circulate through my body. Doing this certainly worked and I will continue this throughout the rest of my life

Ellen  (Patient)

Rebecca is an outstanding practitioner! Her knowledge of techniques designed to alleviate / correct physical discomfort and place patients back in their normal lifestyles is outstanding!

James  (Patient)

I have rheumatoid arthritis and recently discovered I have age-related osteoarthritis in my cervical spine. Rebecca and Alex and Ionie have been working with me and I’ve seen improvement. They gave me exercises, ergonomic instructions for my workspace, and general guidance on how to minimize the impact to my daily life. Because of them, my flexibility, range of motion, and comfort are improved!

G.S.  (Patient)

Josh, Rebecca, Lindsay, and Angela were all wonderful! They made me feel comfortable and made the PT fun.  I would absolutely recommend ARA to friends and family as they are awesome. The office has a great positive atmosphere.

I had a really bad fall in 2006 resulting in permanent disability. Katie has helped me improve my quality of life. 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.

Anne T.  (Patient)

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

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 uses a comprehensive approach to physical therapy incorporating therapeutic exercises, manual techniques and patient education to achieve the best outcomes possible. He prides himself on instructing patients about how to protect themselves and prevent future injuries, thus empowering them to speed up their healing process.

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!
