I had my regular screening colonoscopy with Dr. Onuma recently. Everything went well. I was able to reach the office and make an appointment immediately. The office had a pleasant atmosphere and there was very little wait time. All staff were friendly and efficient, as was Dr. Onuma. The procedure was done at Peninsula Endoscopy and they are great.
