      Dr. Dietz and the UCSF team is amazing! I had to go to the ER and they all commented on Dr. Dietz's note. How it was so thorough and helpful. And while in the hospital, Dr. Dietz has been available to the hospitalists managing my care. Everyone commented how much they appreciated him. I know when I need medical help, Dr. Dietz always has my best interest in mind.
