Read what our patients have to say...

  • It is difficult to count the number of times Dr. Karl S. saved me from going to an orthopedic surgeon and kept me on the tennis court. He immediately takes away my knee pain with a minor manipulation. No need for arthroscopy. See Dr. Karl instead!

    Peter C.

  • Doc Karl is my go to man for my lower back pain. He understands the human body and he explains everything very clearly for us people that need exactly that. I have told coworkers about OPTS so that alone shows how impressed I've been. That is not something I usually do. Thank you Doc. I'll be back when needed.

    Richard S.

  • I thank you for your help and for the advice you have given to me. I believe you did as much as you could for me considering my situation with my back.

    Dr. Joseph C.

  • Dr. Karl Sheaffer is a superior Physical Therapist who takes his job seriously and really knows his specialty. He has treated me & my children for a variety of injuries/issues over many years. Dr Karl is always spot-on with his diagnosis and treatments. His wife Cindy is cheery & keeps the front office running smoothly. I highly recommend this practice if you're in need of some PT magic!

    Kathy G.

  • Before going for surgery, let Dr. Sheaffer evaluate your symptoms, a minor tear doesn't always require surgery, just physical therapy. If you do require surgery, TELL your surgeon where you are going for P.T. and Don't let them tell or sway you otherwise, You do have a CHOICE in your healthcare. They always \"recommend\" their own in house P.T. factory, not the best Physical Therapist.

Welcome to Orthopedic Physical Therapy Specialists in Allentown, PA

Call Today, Get Started Tomorrow

Orthopedic Physical Therapy Specialists is a veteran owned business. It is owned and operated by Dr. Karl J. Sheaffer, DPT, and his wife Cynthia Sheaffer, PTA.

OPTS is committed to providing expert one-on-one, hands-on care to each of our patients. This personalized treatment from the time of initial evaluation through the entire rehabilitation process is what sets OPTS apart from the large volume-oriented practices that are so common today. Dr. Sheaffer focuses on resolving the cause of your condition. He achieves outstanding results by resolving problems, not treating symptoms. Our patients are treated by the same physical therapist for each and every session. Dr. Sheaffer will customize a physical therapy program to the individual needs of each patient.

Direct Access

Direct Access permits specially licensed physical therapists to evaluate and treat patients without a physician's prescription for the first 30 days of care. What does this mean for our patients? Care without delay.
