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.

I recently had a friend move into this area from out of state and I tried to get him into this office with Dr Nguyen but he wasn’t taking new patients…but everyone in this office is great. The people who reply to mychart questions are WONDERFUL…so I got him into this office with the new doctor. My friend already appreciates how much better his care is than what he had in California.
