See What Our Happy Patients Say

“The C.J. Allen OT Upper Extremity & Hand Therapy Team was fantastic! From the intake phone call, I could tell I was dealing with a professional, patient-centered establishment. Check-in was a breeze, and the staff was very cordial and friendly. C. J. introduced himself, thoroughly assessed my issue, and examined my complaint, and within the hour, I was heading out the door with a custom-fitted splint to stabilize my issue and help in the healing process. Today was one week ago, and my hand is feeling better! I’m sure that with the next phase of physical therapy, I will be in good hands!”
