“I feel confident in the doctor's judgement. I would advise Dr. O'Brien to alert his appointment staff as to the nature of the patient's visit so that the EKG and Echo cardiogram can be scheduled ON THE SAME DAY, thus avoiding an extra trip(cost of transport, waste of patient's time). Respect for the patient's time is an important factor in satisfaction with the practice.”
