Dr. Thieu is great. I love how I am seen by a nurse/tech almost immediately and then by the doctor within a few minutes. Dr. Thieu is thorough, open to questions, and explains things without too much medical jargon. It's notlike at other docs' offices where they're in and out within 30 seconds. He'll actually take time with you! Highly recommend this practice.

Dr. Thieu was excellent, he listened to my concerns, addressed them without making me feel bad for getting too much sun (as a child - as another dermatologist had). I required a biopsy which he did swiftly and painlessly. When Iexpressed some concern over an extremely large "age spot", he gave me an option for making it barely noticeable. I will be changing to him for my regular yearly check up!

Dr. Thieu was very apologetic about the wait, but I realized that is was towards the end of the day and that backups are inevitable. He acted as if he has seen my skin condition before and diagnosis was quick. Theremainder of the time was spent discussing the best plan of action and getting a sample of a mole for testing. He listened when I told him of past attempts to address the problem, things that I thought might have exasperated the issues and how prescription attempts at resolution were no more effective than OTC. He didn't leave me feeling that things would not get better although he did let me know that all we could do was treat, not cure. I don't know if things will get better yet, but I do know that this doc will be there and that we will take this problem on as a team.

Dr. Thieu was very professional and helpful. He answered all the questions that I had during the appointment and was able to remove a skin tag without any pain or discomfort. I was able to book an appointment for the sameweek, and my wait time in the office was short. It had been multiple years since my last dermatology appointment, but I would certainly recommend Dr. Thieu if you're looking in the King of Prussia area!

I feel like Dr Khanh took the necessary time to listen to me, ask appropriate questions, and we were on the same page for treatment. His office was nice and well kept. I was slightly disappointed with the wait time. Iarrived 15 minutes early and checked in immediately upon entering. I wasnt seen by the Dr until at least 45 minutes after my appointment time.
