This is first time I saw Dr. Imatani, and it is for upcoming surgery on my Gall Stones and Bladder. I was very impressed with this Doctor, and highly recommend him.

Dr Imatani is a wonderful caring doctor and person.

Took care to explain the procedure and invite my questions. Highly recommended by several other doctors. Gave me a strong sense of confidence in a positive outcome. Followed up a week after the surgery to assess my condition. Gave me an "all clear, return to normal activities" date and reasonable limits til then.

I trust this physician's opinions and judgement and value the time during our medical visits. He has a very good demeanor and communication style that I appreciate.

Dr. Imatani does not only know his field of medicine, he made me feel completely safe in his care.

He is always ready to answer my questions and takes the time to listen and gives answers that I can understand. He makes me feel that he really cares about me as a person.

Dr Imatani has been great to consult with. His assistant [...] is the best I've encountered!

The care and support I have received leading up to and including being diagnosed with [...] breast cancer has been beyond amazing. At each step along the way providers have taken the lead in contacting me and being sure that I have been seen as quickly as possible. All procedures were clearly explained and my comfort was always of primary importance. Dr. Imatani spent much time with my family and me, fully going over breast cancer, surgery and treatment. At this point my overwhelming feeling is gratitude for exceptional care.

very impressed with all 3 of the immediate care providers I have seen in the Main Providence Center, as well as the Breast Center Radiologists and staff.

all good

Dr. Imatani has always been very helpful and respectful during office visits. He always explains all information so that it is easily understood. And answers all questions I have.

Dr. Imatani is a very soft spoken man who listened to how I wanted to treat my breast cancer. He told me exactly how my treatment plan would be executed, how my surgery would be conducted, and he referred me to the plastic sugeon who would do the reconstruction. I have the utmost confidence in Dr Imatani and Dr. [...]. They both will do a wonderful job!

Dr. Imatani is extremely knowledgable and up to date in breast cancer concerns.
