Testimonials from patients of Dr. Ritzo

from Howard in CA March 10, 2024 for Dale J. Ritzo, MD

Dr. Dale J Ritzo has been my personal physician for over 40 years. He is amazingly knowledgeable and explains issues and treatment in layman's terms. His comfort care is always on call. His smile is his moniker. He is extremely patient with me, as I sometimes need clarification on certain issues and terms. In the darkest of days, he also tended to my wife's issues with home… See more

from Irwin in CA March 10, 2024 for Dale J. Ritzo, MD

Dr. Dale Ritzo of San Mateo saved my life twelve years ago. This was a result of his very thorough initial exam. Even though I had two clean colonoscopy results five and ten years prior to my exam with him and no symptoms, he discovered an occult colon cancer. The name of game in this case is early detection and treatment and he played it perfectly.
I will be forever grateful,

His patience for listening to my concerns and his recommendations are by far the best I have received.

from Elizabeth in CA February 12, 2024 for Dale J. Ritzo, MD

I am always amazed by how he affords the time to listen to all my ailments and I do have a few. And then easily goes over them one by one, and finds some solutions to most.Elizabeth

from CAROLYN in CA February 12, 2024 for Dale J. Ritzo, MD

Our parents are 95 and 99 years old respectively. Neither are very mobile and reluctant to go to a doctor. Dr. Ritzo regularly makes home visits to them to make sure they are in good health and spirits. We are so grateful!

I have the best doctor in the world. Not only does he discover things before they are serious, but each year as we sit down in his office to review my annual physical tests, we talk about baseball. His son Joe is an announcer for the San Francisco Giants. Dad is a fan. Once we get that out of the way, we get down to looking at the lab tests. Thank God they are normal, and may that be the case… See more
