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.

Wow - Dr. Kumasaka is seriously the best ever. Like, truly the GOAT of pediatricians. He's kind, patient, and somehow always knows exactly what to say. We honestly don't know how we got this lucky. Total superstar.
