I've had bad experiences with dermatologists in the past so I wasn't thrilled when my regular doctor told me I shouldgo for a yearly exam. They recommended Dr Thieu and I'm glad I went! The office is very nice, modern and clean. My wait was very short. Dr. Thieu was very thorough. He answered all of my questions and concerns.

The wait was a little long but the visit itself was very quick and straight forward. They gave me a lot of comfort knowing what was going on with my situation. I’d recommend them but suggest to expect to be there about an hour altogether.

Dr Thieu was very kind and helped me to understand my skin problems and recommended an adequate solution. I also appreciated that he recommended a specialty pharmacy to help save me some money on my Rx since most Dermatology prescriptions aren’t covered under my health insurance. It definitely saved me a lot of money versus going to a CVS or Walgreens pharmacy. I will definitely be seeing him again in the future. Additionally the office is very clean and modern looking.

Dr. Thieu is friendly and the wait wasn't long at all to see him. Unfortunately, I didn't feel he was confident dealing with darker skin. He immediately placed my skin condition in a very broad category due to my dark complexion, even though my medical history says differently. I grew up going to dermatologists regularly and can tell when someone isn't sure how to approach my skin. If you have light skin, I definitely think he will take care of you. Unfortunately, I cannot recommend him for folks with more melanin.

First time visit with this doctor for annual skin screening. He's very nice, down to earth, and answers all of your questions. He's obviously very smart, too. It's difficult to find doctors (especially specialists) that have great bedside manner, are reassuring, and don't rush. Don't hesitate to schedule an appt. with Dr. Thieu for any reason. Great experience overall!

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 not like 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 I expressed 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!
