Patient Reviews
Jan 31, 2020
Dr. Sean To has been my Doctor for many years. He has always taken the time to explain the various medical conditions I have under his treatment. Thanks to Dr. To my cholesterol levels went from very high to normal. He was just as happy as I was when my blood work results came back with good results.
