Patient Reviews

Patient

★★★★★

I have been Dr Bayon's patient for nearly two decades his professionalism has helped save my life at least twice. Also, when I need to get any help or diagnosis, he gets me in within a day. Office staff is always happy and helpful. Even though I now have VA disability, I keep him as my go to primary. He is a wonderful physician.

I had the pleasure of being one of Dr. Bayon's patient for the past 2 years. I moved out of state and sadly had to end the best Dr./Patient relationship I've ever had. Dr. Bayon had a great personality and always was able to put a smile on my face whenever I had an appointment with him. His was extremely knowledgeable and always gave me the best advice regarding my health care, but never once did he push me into something I wasn't comfortable with. He always gave me the information and let me make the final decision. His staff was always friendly and helpful, and the office was clean and orderly. I highly recommend Dr. Bayon to anyone seeking a qualified PCP!

★★

This received two stars mainly because of the office staff themselves. Dr. Bayon is a wonderful doctor and is tentative to his patients. He is straight forward but in an empathetic and caring way (not rude). My family has been a part of this practice for years. My two younger sisters and I were patients of Dr. Nguyen when we were in pediatrics and my step-father was a patient of Dr. Bayon's for years before he switched insurance. The DOCTORS are one of the many reasons I started to see Dr. Bayon as my primary. I event had a chance to see Dr. Yoshisato when he was out of the office and she is very sweet. Some of the staff in this office however can make you feel less confident in the care that you are receiving due to the incompetence. Messages are not always relayed correctly, you do not always get a response within the time frame advised, and they make you feel as though your care is not important. It is extremely frustrating when you do not get the same treatment or quality of care throughout the entire office. Unfortunately, I can not continue to go here knowing that information may or may not be related and that I may or may not be treated kindly.

Misdiagnosed my father's Parkinson's, so my dad suffered for almost two years without appropriate care. My father now has a blood clot because he advised my dad to lay down much more than needed post-op.
