Your Non-Surgical Back and Joint Pain Specialists

Your Non-Surgical Back and Joint Pain Specialists

Any amount of pain can be a nuisance in your life, especially when it lasts a while. Everyone deals with pain differently, and there are many options available to treat it.  Narcotics and pain medications are one common option, but the best possible option for most painful orthopedic conditions is a good Physical Therapy Doctor.

Many patients are often looking for the “magic bullet” to immediately fix their back or joint pain.  Pain medications can often give them the most immediate short-term relieve, but they do not solve the problem and can have many long-term negative effects. 

Physical therapy, on the other hand, offers a wide range of possible benefits that far outweigh any risks involved.  Unlike pain meds which are only meant to mask your perception of pain.  A good Physical Therapy Doctor will focus on finding the origin of your orthopedic pain and work on improving the mobility of your painful areas, as well as the stability of the surrounding areas.  This will result in a far superior long-term outcome and allow you to live a more active life.

Our Vision

To improve Florida’s healthcare and the health of it residents, by addressing the root cause of their musculoskeletal pain and dysfunction. Therefore, reducing the use of pain masking agents, such as opioids and limiting surgery to an option of last resort. Reducing both the costs of healthcare and the unforeseen consequences that may arise from these less safe and costlier alternatives.

Our Mission

The mission of Physical Therapy Doctors of Florida is to help the members of our community to live more active and fulfilling lives, by maintaining and improving their overall health and fitness, as a result of providing them with high-quality physical therapy care and exceptional customer service.
