Nathaniel Creznic, DPT, Cert. MDT

  • Physical Therapist
  • Doctor of Physical Therapy
  • Certified in Mechanical Diagnosis and Therapy

When people experience pain, it is common to be limited with activities and not fully enjoy life. My passion is to show you how to control your pain with individualized exercises. This way you can fully participate in desired activities.

I know each person is different and no single approach works for every individual, so I have extra training to customize the exercises to your ability. My training includes a doctorate degree from Lebanon Valley College in Annville, PA. I also have a Certification in Mechanical Diagnosis and Therapy from the McKenzie Institute USA.

Another passion of mine is my family. I am married with three children. We enjoy spending time together; whether their soccer games, going to the park, or for hikes.

Our goal at Commonhealth Physical Therapy is to empower you to control and eliminate your pain so that you can enjoy life again!
