  • Dr. Douglas Nguyen made me feel comfortable and confident in my upcoming procedures. Very personable and friendly.
    I am coming to Dr. Nguyen after a bad experience with a doctor that is not part of Providence, Mission Heritage. When I got there I was greeted by one of the receptionists. He told me his name, got signatures and off I sat to wait to be called. I waited less than 5 mins In the waiting room before I was called back. The nurse took me to a room and asked me a few question. It was only 2-3 mins before the doctor came In and Introduced himself to me. Dr. N was amazing! He was very knowledgeable, kind, respectful and knew how to get a plan in action for me. He was quick but did not rush me or make me feel rushed. He explained how he thinks I got this problem and what meds I would need to help the problem. He spoke with me how he can help two of my issues with one medication. And how that medication would be administered. Hr assured me he was going to get me feeling better. I am so happy with my care from this doctor and would recommend Dr Nguyen to all of my family and friends. He cares about his patients.
    This provider is the best GI provider I ever visited. He is so good that he gives you hope, that is what I like about him.Please, do not let him go
    For the provider not to presume what question the patient is going to ask and an answer without letting the patient finish their question. For the provider to explain recommended procedures in detail such as an endoscopy since not everyone has had one before. For the provider to be fully engaged and not distracted while on the virtual call.
