Patient Comments
I appreciated how the doctor showed and explained the related imaging results.
Jul 08, 2024
Dr Tomiyama was genuine in his care & concern for my concerns
Jun 21, 2024
He was as top notch as my previously visited provider there [...].
Jun 05, 2024
The smiles on both dr's. faces and overall positivity made the experience THAT much greater.
Apr 04, 2024
I have interacted with my providers across many institutions. Dr. Tomiyama is by far the best, most caring, articulate provider of them all. This space is so inadequate to detail how good he is. Highly recommend.
Sep 27, 2023
Helpful discussion about pros and cons of needed follow up. Dr. Tomiyama was thoughtful and effective in describing reasons and we reached a consensus that it is probably not necessary to follow up unless symptoms change.
Jul 27, 2022
Awesome.
Jul 25, 2022
My sister and I were pretty impressed how well the procedure was explained.
