Providence Patient
This was my first visit to Dr. Niel Tran. I discussed with him my concerns going forward on a change to my therapy for my borderline diabetes and A1c level. We talked about adding Mounjaro therapy, and he said that his focus was for me to easily tolerate the change. We also talked about as this change takes effect that he might remove me from Januvia. I asked him as I progress if he might reduce and/or remove Metformin from my therapy. He said that was a great question, and that over the next year it could be possible. I had a very thorough discussion with him.
Providence Patient
This visit was very good. I have had issues with call backs from the office. Because it was the day after Christmas, the office was pretty calm and laid back
Providence Patient
So far, since he started being my Endocrinologist, I was comfortable with the care he provides. He'll explain anything you would like to be emphasized making sure I understood what he had expressed, if it's not too clear to me, I would ask him for re- explanation for me to understand better.He's a nice Doctor & explain further what I didn't understand. I started having Osteoporosis since the beginning of my visit with him and placed me on oral medication for a long while, however it didn't seem to work with my Osteoporosis problem so he started switching me to PROLIA being given intramuscularly every six months & In July will be my next dose.
Providence Patient
He remembers details about me and spends time discussing any concerns he or I have about my health. He also takes an interest in me as a whole person. Since I have no complications with my thyroid management we have time to chat about other things which helps us to inspire each other.
Providence Patient
Professional, interested in my care, spends appropriate time.
Providence Patient
Always excellent experience with this doctor.
Providence Patient
I know that Dr. Tran is very good at what he does and is a good doctor. But like many other endocrinologists, and various doctors, he doesn't have a lot of guidance re: Reactive Hypoglycemia. He gave me a paper on it, but there's a lot to it. It's really not easy to deal with! He said something like he doesn't have a magic wand to whisk it away or something like that. I wish there was a magic spell to take it away! In the meantime, I do need some support and help. I'll probably look for a naturopath. I didn't get the feeling that Dr. Tran wanted me to continue with him. I'll stay with current endo I have that I'm just checking in with once a year because he said "you don't need me". This is the common answer re: hypoglycemia that's not severe, but I do still need support, because if I go really low it's scary. I know. Have all the tools at my fingertips however. Thank you. I just don't think everything should be based on testing and he started talking about heart stuff when I've never had heart issues but he brought it up because it's in my family on mom and dad's side. That was connected to cholesterol issue...I'm borderline high cholesterol, but I came there to to be helped with the Reactive Hypoglycemia.
Providence Patient
Dr. Tran and his team are great! I am very grateful for their excellent medical care and truly appreciate their sincerely and concern for my well being. They are a joy to work with.

Providence Patient
Dr. Tran is very thorough and competent. Despite his cordial manner, I would feel more comfortable with him, if he did not appear to be in a hurry. When I told him that my eye doctor recently discovered that I have Left Side exophthalmia, he did not respond or show any interest. I'm not sure he even heard me, as he seemed pressured to end the visit quickly.
