I brought my mother here about 3 weeks ago for her arrhythmia. I was referred here by a family friend. The wait time was very little in the office and the staff in front were very nice and helpful. Dr. Ong was very patient with us and answered all of our questions in a helpful and informative way. His input was really encouraging to my mother, as she had been very worried before coming into the office. Considering how many patients Dr. Ong deals with on a regular basis, I was surprised how much time he took to help us specifically. Knowing that my mom is in his good care takes a lot off of my head.
