"I have seen Dr. Dang Nguyen only one time and have not been treated as of yet, however, I decided to go ahead and write this review because I am already impressed with the Doctor and staff. First of all, Dr. Nguyen LISTENS and this is very important to me as a patient as I have a total fear of doctors these days that only see one way and one way only. He was also confident, and that made me feel safe and secure in his hands. I hope that everything continues to be this way. I was also to have a procedure done, but could/did not do so because I was afraid of insurance issues and such, and I received a phone call from Natalia, one of the staff members at the office, and she was SOOOOO thorough and amazing in telling me and letting me know how it works with procedures and cost; NO OTHER MEDICAL STAFF WORKER IN HOUSTON EVER EXPLAINED it as she did where it was easy to understand....not even my own insurance provider that I am under! She is truly amazing! I really hope that all continues to go well with my experiences with Dr. Nguyen and his offices/staff."
"Wonderful doctor! Dr. Nguyen made me feel comfortable and was very knowledgeable."
