Natalie Napoleon – Wahiawa Office Manager

Hi! My name is Natalie Napoleon and I am the receptionist at Central Oahu Physical Therapy Specialists in Wahiawa.  I’ve been in healthcare for many years and enjoy meeting new people. When I’m not at work serving our valued patients, I am a full time Mom of 4 wonderful boys. I love watching them play baseball, football, and everyday is an adventure!  COPTS is like a family and I’m happy to be a part of it. I look forward to meeting you and answering any questions/concerns you have. Stop by or give me a call!


  • I've benefited in so many ways: improved my functionality, learned to re-educate my muscles "slowly", and continued to maintain a pro-active attitude by taking control of my healing.

  • I appreciate, very much, that you thoroughly explained the purpose of the exercises - it is more meaningful when doing the exercise, to know its purpose.
