    she was very knowledgeable about my disease and informed me about health concerns I should be concerned about that I had previously not been informed of great visit wonderful Doctor.

    Dr. Troung takes time, seems genuinely concerned and I feel is extremely knowledgable and I always leave feeling well taken care of and informed. She is an extremely good Dr.

    National Jewish Health PatientMay, 2016
    I would like for her to provide more details and medical information about my conditions, blood work, what it means and also providing copies of blood work with me and going over them in more detail. I'm very confident in her knowledge and only complaint is that I'd really like to understand the condition and medical diagnoses in more depth -- additional diagnostics would be appreciated to further pinpoint the disease when I experience flares.

    National Jewish Health PatientJanuary, 2016
    My insurance did not approve my continuing care with Dr. Truong. I paid out of pocket to see Dr. Truong, and will continue to do so..... I firmly believe she saved my life, and the insurance will not make the decision that I will go somewhere else. Dr. Troung is marvelous.
