Dr. O'Riordan has been outstanding to deal with through many years - for myself and other family members. He truly cares and here is a rarity with doctors (in my experience) Dr. O'Riordan LISTENS. He hears you and works with you. I appreciate his compassion, empathy, knowledge and advise. I am comfortable and happy in his care.
