Dr. Sugimoto is an outstanding doctor. He took over my previous [omitted], Dr. Villasenor, and Dr. Sugimoto has been right on top of all my exams and physical needs that he took over from Dr. Villasenor. I would highly recommend Dr. Sugimoto, he is professional and courteous - especially to us[omitted]!
