About Chelmsford Chiropractic Center

Chelmsford Chiropractic Center was started by Dr. Fischer in 1990. Previously located within its own building on Turnpike Rd in Chelmsford, Dr. Fischer had a therapy room, 3 adjustment rooms, a gym open to his patients, and an X-ray machine on site. 5 years ago, after colleague doctors moved onto their own practices the doctor moved to the center of town to 6 Boston Rd, his current practice. There is no longer a gym or private X-ray area but that doesn't mean we believe any less in the usefulness of diagnostic X-rays and physical health. Our Doctors encourage exercise and are happy to suggest exercises which will strengthen muscles and reduce pain. We refer patients to Mass General Imaging of Chelmsford, a walk in X-ray location which is right down the road with the newest digital equipment. They review the X-rays and send us a report on the patient's condition, giving our doctors another professional opinion to discuss with you. To offer our patients the most flexibility when scheduling and choice of chiropractic care we welcomed Dr. Brian Farrell to our practice. Patients can treat seamlessly between the 2 doctors and utilize the skills of either doctor for their current concerns.

Chiropractor of Record
Dr. Karl B. Fischer, Jr. has been a privately practicing chiropractor over 25 years and has seen over 5,000 people in this practice alone. He is an alumnus of Life Chiropractic College, the largest chiropractic college in the world. In 1995 Dr. Fischer was the President of Middlesex Chiropractic Society. Although many people think that chiropractic is just for the treatment of their back or neck, this is an incorrect assumption. Chelmsford Chiropractic Center focuses on the health of the whole body! Believe it or not, headaches can be caused by a misalignment of the neck. Your knee or elbow joints can hurt if a hip or shoulder is out of place. Dr. Fischer manipulates the spine and extremities and realigns the bones to where they're supposed to be. Dr. Fischer has had great success treating headaches, sciatica, joint pain in knees, ankles, wrists, elbows, and more.

Dr. Fischer treats patients Mondays, Wednesdays, Fridays and Saturdays.

Reviews By Our Satisfied Patients

  • "As an award winning runner I rely on Dr. Fischer to keep me going. I am top of my age group and I feel chiropractic is essential to that. The adjustments combined with the many therapies Dr. Fischer offers keeps me going and allows me to continue running. I always stop in right before the Boston Marathon so I am fully ready. My son is also a runner who is nationally recognized in his age group. I can trust Dr. Fischer to treat my son just as he does me and keep our whole family going strong. As a teacher I can attest to how chiropractic enhances brain development and coordination. That’s why I know chiropractic is an important part of my life as well as my family’s."

    Our shoulder joints have the greatest range of motion of any of the musculoskeletal joints in our bodies. The shoulder joint is really two joints, the glenohumeral joint between the arm bone (humerus) and the shoulder blade (scapula) and the acromioclavicular joint between the acromion (a bony projection off the scapula) and the collarbone (clavicle). The glenohumeral joint is a ball-and-socket joint and the acromioclavicular joint is a gliding joint. ...

  • An Apple a Day . . .

    What is so good about an apple? Is it the color, ranging from ruby red to pale pink? Is it the crunch? The sweetness? Or is it, instead, a combination of all of these qualities, plus the natural goodness derived from the apple's secret ingredients — phytonutrients? If this were a multiple choice quiz, the answer would be "all of the above". Importantly, in addition to possessing numerous appealing physical qualities, apples contain an abundance of health-promoting biochemicals known as phytonutrients.1,2 These specific organic molecules are derived not only from apples but many other fresh fruits and vegetables, and help power the immune system, protect against cancer, maintain healthy eyes, and assist cells in clearing out metabolic waste products such as free radicals. ...
