I have fibromyalgia, shoulder pain and back pain. Kelson helped me a great deal. He gave me good tips and was very thorough in his explanations of exercises. I would recommend ARTS because I was not “treated like a number”. Kelson was very aware of my issues and dealt with them. Kelson was always prepared to treat me and always remembered everything we had discussed. I also found everyone in the office pleasant, welcoming and professional.

Michelle L. (Patient)

For years, I have suffered with pain in my back, hips and lately in my hands. My rheumatologist recommended physical therapy since I can’t tolerate prescription medicines. Ever since I started physical therapy, my pains have reduced the intensity and I have been able to move with more flexibility. I am able to work around the house and walk for 20 minutes without pain. I have already recommended a friend to ARTS, because of my wonderful experience with Kelson and my recovery!

Marta V.  (Patient)

I came to ARTS with both chronic lower back issues and an acute injury in my right leg. Over the last year, I have been very physically active, and was training for a challenging race. Kelson helped me understand the cause of my pain and was fantastic at working with me to both help me heal and not totally backtracking from my longer term training goals. I feel like I didn’t just have my immediate issues addressed, I also have information that will help with my training moving forward. I am very happy with my therapist, Kelson. I learned a lot more about the issues I have been having with my back, why they happen and how I can prevent or improve them.

 pt-theresa-wheatonTeresa Ichniowski, PT

 During her years as a Physical Therapist, Teresa has worked in a variety of settings including hospitals, skilled nursing facilities, outpatient centers and home care services. Her broad range of experience is a valuable asset to ARTS and to her patients.

 Teresa has a special interest in Osteoporosis and has pursued additional training in exercise protocols that improve posture and balance to protect against falls. Recently she has begun teaching a course designed to benefit individuals with this condition as part of the new ARTS Wellness Program. 

I came for P.T. a month after I had knee replacement o my left leg. Teresa took excellent care of me as usual and gave me exercises and tips so I could get better. Helping out were Darcy, Kwesi and Brendan who pushed me so the exercises were helping out more every week. I feel that everything they all did for me and tips to do things better and easier at home all got me to where I am today. NO PAIN, but some minimal discomfort. I have told my friends about the excellent help I was getting with the therapy.

Barbara D.  (Patient)

I was referred for physical therapy by Dr. Thomas because of spinal osteoporosis. In five sessions I have learned a routine (originated by Meeks) that reduces discomfort and has improved my posture.

Mary M.  (Patient)

I had a problem with my right shoulder. It created so much pain to perform my routine activities. Dr. Matsumoto sent me to see the P.T., and Teresa was the person. I have been very impressed with her regarding the treatments, and her hospitality. I have recovered very fast due to her treatment and instructions to exercise. I am very thankful to her and all the staff.

Sodsai T.  (Patient)

I had pain in my left shoulder/shoulder blade.  After awhile my right shoulder joined with pain.  Both were addressed with treatment. Teresa, my therapist has been very caring. I liked her approach to avoid pain and her gentle, but firm touch. The most valuable aspect of my experience was that approach to avoid pain when doing my daily exercises.  

Rachel G.  (Patient)

I came to physical therapy with pain due to joint hyper mobility.  The pain included my shoulders, back, knees, hips and ankles.  Teresa very skillfully showed me how to manage my condition with exercise.  My pain has been greatly reduced.  Both she and Laura always treated me with gentleness and kindness. Teresa tailored my plan to my individual needs. They communicated everything with my physician.   It has been a joy working with them.  They have treated me like family!  And my life has improved by being able to better manage my pain from this chronic condition.

Henry Francis, DPT

Henry Francis obtained his Bachelor’s degree in Health Science in 2010 and later earned his Doctorate of Physical Therapy in 2013 from Howard University in Washington, DC. It was there Henry developed a passion to work with geriatric, chronic pain and orthopedic populations. During physical therapy school, his research project, “Survey of Mississippi National Medical Association and the Jackson, Mississippi General Public’s Knowledge and Perception of the Scope of Physical Therapy Practice”, analyzed both physician’s and the public population’s perception of Physical Therapy. Henry was familiar with Arthritis and Rheumatism, as a former Student Physical Therapist. Upon graduation, he received the Lynne Suzonne McClain Memorial Award, an award for students who exemplified excellent professional development. Henry also competed in track and field at his alma mater Howard University where the former athlete developed an understanding of the proper biomechanics of running. Throughout his physical therapy career, Henry had the opportunity to serve a multitude of populations including orthopedic, geriatric, neurological, sports and cardiac conditions. He earned his Dry Needling certification from the highly reputable, Myopain Seminars. Also to mention, he studied Continued Educational Courses in Kinesiotaping and Graston Technique. Meanwhile, Henry is ambitious to hone his craft in Posture Awareness & Alignment. Since joining Arthritis and Rheumatism Associates, he is very excited to work with the arthritic and chronic pain population.

Henry, my physical therapist, has helped me a great deal, although I am not without pain or some difficulties getting around. When I came in, I was using a cane and I could not bend my left knee. I am now walking without a cane, and bending both knees. I did have a setback during my therapy, but Henry got me through this and answered my many questions. I do think having only one therapist for every session helped me.

Patricia  (Patient)

Ski injury in 2001, ACL tear – repaired. Two meniscus tears after; two additional surgeries. Released from that P.T. w/o sufficient treatment. Subsequent injuries to right knee; very stiff, with half the range of motion. This current physical therapy seems to be helping tremendously with pain, stiffness and range of motion. Also, much improvement after dry needling with Henry. The staff is knowledgeable and the treatment helps a great deal.

Theresa  (Patient)

Henry is very thorough. He is actually listening to me. His approach during the session is varied; including exercises, manipulation of the pressure points and other techniques. During falre-ups, I am able to apply the techniques he has taught me to manage the pain. The staff is also thoughtful, professional and caring.

Rebecca Wagner, LPTA

pt-rebecca-rockvilleRebecca Wagner received her Associate of Applied Science degree with honors from Montgomery College, Takoma Park and has been practicing as a Physical Therapy Assistant (PTA) for more than 10 years. As a PTA, Rebecca has contributed to the well-being of her patients by providing both education and treatment to help them achieve their clinical goals and regain functional mobility. 

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.     

Regina A. (Patient)

All the staff and Rebecca are extremely wonderful.  It is a pleasure doing physical therapy with this group.

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!
