    Doctor Sugimoto, Truly cares for his patience. He makes you sure you understand the procedures and treatments, and medications. He takes time to understand you questions and concerns, and he responds very professional and clarifies. Any doubts that you may have. Overall, it’s great to have a doctor that cares for his patience.

    I have been going to the Sienna Clinic for 3 years. My previous doctor relocated and I was not sure what to expect. This was my first appointment with Dr. Sugimoto. He was patient and addressed my issues from past and present and took the time to explain things so I understood. The Referrals and new prescriptions are taking care of my needs so far without issues. I felt very comfortable with Dr.Sugimoto and look forward to seeing and consulting him in the future
