Real Clients, Real Reviews

I was very pleased. I waited less than 5 minutes before I was taken to an examination room. Nurse Practioner, Ms. Yoshida, was very thorough and let me know what tests or procedures that I, as a 66 year old woman, should be getting.

She was easy to talk with and addressed all of my concerns. The staff was very efficient and friendly. I will be recommending Centennial Medical Group to my friends and acquaintances.
