Dr Oconnor has always been kind, compassionate and very thorough. He explains everything in detail. I am heartbroken to hear he is leaving his office in Sterling. I don't know where I'll go. He is an excellent cardiologist!!

Dr O'Connor is excellent and the staff at the practice are wonderful as well. Special thanks to the lady that did my EKG, I believe her name was JJ, for being incredibly professional and kind.
