Dr Kumasaka is absolutely the best. He truly listens and does a thorough check up. The only reason I sent a f/u message & received a call back is because my husband didn't grasp the after care instructions so I called to make sure I understood.

This doctor was so kind and positive. We've never been seen by him before, but he immediately put us at ease when he walked into the room. Such a warm, caring, and kind spirit. He put my daughter at ease right away!

Dr. Kumasaka and staff have been my twins providers for 11 years. This is the best quality care and I am always so happy with the care we receive. I feel they spend time with our family, take our concerns seriously, and give great medical advice and treatment. I am super grateful that I was able to have such a wonderful care team for my children.
