    First visit my husband was referred for a surgery clearance. The Receptionist was extremely rude,…read morebut we chalked it up to a bad day. Second visit, another receptionist was rude. This person told my husband (who had to get off work early) that he would not be seen because he didn't have (1) proof of a Covid vaccine or (2) not one, but two negative Covid tests. This was never told to him when he made the appointment. When he explained that he was never told, the receptionist proceeded to ask the doctor if he could still be seen. The doctor refused to see him. The excuse, because Covid has to do with the lungs. Hmmmm...that seems so strange to us considering our Dentist (who has no stipulations) saw us recently. You would think a Dentist would require something since they are so close to the mouth and in your face. It's a literal Covid Fiesta at a Dentist office. I must add that my husband works for the County (he worked through the pandemic). He has been tested numerous times (all negative), but he was not going to reveal this information. Why? Because at this point it's the CONSISTENT unprofessional behavior from the staff. It's the...Oh well, we don't care that we inconvenienced you, and your employer to come to our office. It is truly unsettling and an indication that maybe this isn't a right fit for my husbands care.

    Go to the office at your own risk. They have a receptionist/medical assistant named Victoria. My…read moremother's primary care physician referred her to this office for an consultation for an upcoming surgery September of last year. When my mother arrived at the office, this "Victoria" person went off on my mother for not having the $40 co-pay. My mother was not informed about a co-pay. I, at a later date, paid the co-pay, and cancelled any upcoming appointments. We are not wasting any money on nasty receptionists or doctors. It seems like this is becoming the norm treatment for healthcare staff to treat seniors that way.

    I came to Dr. Chang because I had a problem with tonsil stones. I researched all of the options for…read moreyears. I could have my tonsils removed, which at my age might lead to serious complications. I could do nothing and keep trying to manage the situation on my own - which wasn't working out so well. I could have laser cryptolysis, which might cause problems with other tissue in the back of my mouth if something goes wrong. I could have coblation, where only the offending tonsil is resurfaced. I opted for coblation. I researched and researched and researched and Dr. Chang got great marks across the board. After coming to him and having the procedure, I can see why. His office staff were friendly and efficient. You never got the feeling that they were bothered by your questions. They got me all scheduled for surgery very quickly. Dr. Chang offers you options on where you want to have your procedure. You could have it at the hospital or a surgical center he uses. I choose the surgical center. The only thing I didn't like was that the surgical center didn't call until the day before the procedure to give me my actual surgical start time. I was coming from a distance and I would have liked to have known about a week in advance, but I'm not upset about that because when they didn't call me as expected, I called Dr. Chang's office and they sent me in the right direction to get the information. I would just suggest that YOU call the surgical center beforehand (if you don't use the hospital) to ask when to come. I have to add that the surgical center staff were top notch - very friendly, very warm, very welcoming and just the type of people you want around you when you are about to put your life in someone's hands. Aside from the notification issue which I took care of, they were superb. The process and recovery went exactly as Dr. Chang described. Someone called to check on me the day after the surgery and scheduling the follow up appointment was a breeze! I discovered that I felt SO MUCH BETTER after my tonsil healed! It seems that my tonsil and it's associated tonsil stones were poisoning my system! About a week after the surgery, I felt better than I had felt in years! I realized that the constant nausea I had been experiencing for YEARS was a direct result of the tonsil stones! Who knew? Anyway, Dr. Chang and his staff are ALL rockstars! Do yourself a favor and make a weekend out of your visit. Come on a Friday and then go to Luray Caverns after the appointment. The area is just beautiful. I love great service! This doctor ROCKS!

    He acted as though he didn't have time for me, like I was an inconvenience. I felt as though I was…read moreon a conveyor belt and just passed through. Very little to none bedside manner and no time for explanation. I won't be going back. Currently looking for someone else. Also came at me with the nasal scope without notice and when I seemed nervous was extremely sarcastic! Not very pleasant. Do better Sir.
