Although he may come off as a bit “strange”, he has a his own method of doing things that works. I wouldn’t trust any other neurologist to my care, and I haven’t. While hospitalized at a hospital he didn’t have privileges at, a different neurologist took care of me. Upon discharge, I scheduled a follow-up visit with Dr. O’Donell. I’ve been going to him for over 25 years and wouldn’t change for anyone.
