I fell on the ice and suffered a severe concussion. After 4 days in the ICU and 2 additional days in the hospital I was referred to the Allegheny Chesapeake Physical Therapists to see Carley Grennawalt, a therapist who also worked on concussions. She was so knowledgeable on the condition and was so helpful. I would highly recommend Carley and the Allegheny Chesapeake Physical Therapists to anyone. Thank you so much Carley
