Dr. Nguyen is a major improvement over my last primary care physician. Goes over the lab results from all my doctors. Gave me information on some choices I was thinking about making. Nice person to deal with. Not worried about wellness visits and forms for them.

All staff interacted with, were personable, polite & professional. The most appreciated part of the visits were the fact we didn’t feel rushed. Our return to Renown, after a disappointing necessary exit, was successful. Please keep it up as an organization. Thank you.

This office and provider make me feel important and secure

Nov 12, 2025
Dt. Nguyen made me feel very comfortable and told me exactly what he felt I should do. I got a Cat scan appt for the very next day and within an hour or so of completely the Cat scan he called to tell me he was sending referrals for me to follow-up with and if I didn't hear from them to contact them myself. I did hear from them. His follow-up was better than I expected or had received in the past from urgent care or a doctor I had not seen before. GREAT experience!!

Dr. Nguyen Has been the first primary care MD I’ve been to that has taken the time to listen to concerns, communicate clearly on my treatment and preventative care recommendations. I am glad to have him as a provider and hope he is recognized as a true asset by Renown Health.

Dr. Nguyen has been an excellent primary care physician for me. I am a complicated case and he has done an amazing job keeping up with my cancer and autoimmune disease, refering me to specialty physicians as needed. The front desk staff was friendly and efficient, making check-in a breeze.
