  • My visit was virtual and only a pre- procedure consultation. Dr. Chang was nice and knowleagable on the zoom meeting. I'm hoping he is a great practicing doctor as well!
    Dr was excellent and knowledgeable and staff was helpful, wait time for follow up procedures was too LONG in my opinion due to schedule being booked - two months to schedule a surgical procedure needed.
    very good dr
    I believe this physician to be exceptional. he shows sincere concern for his patients. Kudos to him.
    I think Dr Chang is exceptional. He takes all the time needed to assess the problem. While I can tell he is very busy and in demand, I never feel like he takes short cuts - he gives me the amount of time and attention needed.
