      See above. Dr Guy was my internist for many years and I was so pleased to have been assigned to her on weight management by chance.

      After nearly 15 years of struggling with my health, several weight loss programs, and a handful of doctors, Dr. Guy was the one who truly helped me. She approached my health and my goals with compassion, and helped me get to where I needed to be. Her kindness made it easy for me to be honest about my challenges so she could help find solutions, and I never felt judged, ashamed, or afraid to work through those challenges together. I wish all providers approached care the way she does - she made a huge difference In my life.

    Please check with your health insurance plan regarding coverage for this type of care. Not all providers at UCSF Health are covered by every insurance plan.
