Physical therapists provide services that help restore function, improve mobility, relieve pain, and prevent or limit the permanent physical disabilities of patients suffering from injuries or disease. They restore, maintain, and promote overall fitness and health.

Chiropractic is a health care profession that focuses on disorders of the musculoskeletal system and the nervous system, and the effects of these disorders on general health. Chiropractic care is used most often to treat musculoskeletal complaints, including but not limited to back pain, neck pain, pain in the joints of the arms or legs, and headaches.
Active release technique can be used effectively to evaluate the function of the muscles, fasciae, tendons, ligaments and nerves surrounding the affected area. Dysfunctional or abnormal tissues are then treated by the application of proper tension to the dysfunctional area with specific motion. Treat involved structures, by reducing contraction and tension in the muscles, and helping to restore proper movement and function.
Dry Needling (DN) is a skilled intervention performed by a healthcare professional. It is the insertion of a fine filiform needle into the body to stimulate a healing response in the presence of musculoskeletal, neuromuscular, or movement dysfunctions. A variety of patients can benefit from dry needling.

To start my mother who is 65+ went here, she had Andrew as her therapist when he wasn't in she had Jess. Her experience was amazing and the outcome was to the best.
About a year later I myself had shoulder issues. Upon my time Andrew was no longer there. I was suggested to have Jess.
First impression the receptionist Laryssa was sweet, friendly and cheerful. Always helpful to look into insurance questions and she is on top of her game on knowing what's covered and not covered.
Jess was amazing friendly and was great asking follow up questions and suggested Gaston and dry needling for issues

I have been going to Patient first for over 3 years and have had the best experiences with my physical therapist and the up front staff! Before going to Patient first I didn’t believe PT would work, but their PT has changed my mind forever! They are the best!

I’ve been several times to see Mary Ellen for back and hip issues. She’s wonderful! I really like the ART technique, a little painful but so worth it. I always leave feeling so much better. The front desk staff is always accommodating and friendly.

Maryellen is the best chiropractor I’ve ever been to. She’s extremely knowledgeable. I’ve since moved from the Waltham area but still drive 30 miles to see her.

I had one of the worst experiences in getting appointment with this hospital. Firstly the front desk receptionist are very rude and not interested in listening to patients. They hardly receive calls and do not care to listen to voice mails and call back.

Dr. William Cadoo does amazing work. He is very attentive and takes the time to explain the treatments in a very logical and easy to understand manner. He's been very helpful in giving advice for between visits to help with recovery. Would recommend Patient First Chiropractic and especially Dr. Cadoo to anyone in need of a knowledgeable chiropractor.

I was a student volunteer at this clinic doing my observational hours for PT school . The staff is great and I had a wonderful experience with the 3 physical therapists Ryan, Nicole and Andrew. They were all passionate about their work and treated people with respect . Best clinic in the area.
