This "Dr." Will tell you his patient is NOT his problem. He was flippant an lied to me whilst looking me in the eyes. His patient went 2 days with NO help from the so called Dr or the office staff. I was threatened by the "Dr" and his staff. Mainly because they didn't want to hear that they messed up and ignored the patient for 2 days! He is no longer part of my medical team. Formal complaint will go to OSHA and CA. Dept. Of Health. BAD MEDICAL PERSON. Beware

He is a great doctor and always cares for his patients. I had surgery on 4/30/2023 at that time family doctor in Foothill Ranch Hospital told me I had colon cancer on stage 3 or 4 and I had to carry the bag after surgery but when I talked to him, he explained to me that I didn't need to carry a bag and my colon cancer curable. From my own experience Foothill Ranch Hospital under staff and unprofessional. I am really glad he took care of me well and comforted me at critical times "really appreciate it".

Dr. Nguyen performed a hernia surgery on me. He has reportedly performed almost 900 such surgeries using robotics. I couldn't be happier with the results. He gave me his cell phone so I could all him 24/7 after the surgery - I really appreciated that!

I met Dr Nguyen in the ER. He is amazing. He explained things to me so I could understand what he was saying. Every time I saw him I felt as if I was his only patient. I would refer him a million times over.

I had to have emergency gallbladder removal. Dr. Nguyen made me feel at ease with surgery, since this was my first surgery ever at 53. He explained everything in detail, and made me comfortable knowing I was in great hands for surgery. I strongly recommend this doctor. He also has a great personality and very knowledgeable. Thank u Dr. for the great care...... Lourdes

He's an amazing surgeon. He saved my life with his surgical skills when other doctors would have failed. His staff are equally as kind as they are professional. What more can I say. Thank you Dr. Nguyen!
