Dr. Iwahashi is the best primary care physician I have had in many years. He is knowledgeable, attentive, and genuinely listens to my concerns. I have never felt rushed when asking questions or discussing my health and treatment options.The same is true of his entire team. They are responsive, caring, and make you feel that you are part of the process. It truly feels like we are partners, working together to determine what is best for my health and well-being. I am very grateful for the level of care I receive from Dr. Iwahashi and his team.
