    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.

    I couidn't imagine liking my new provider (Michelle Guy) as much as my previous care giver, but honestly, I like her even more. She asks great questions, gives me terrific advice and I truly feel like she understands my situation and needs and picks up from one visit to the next like no time has passed.

    She is a wonderful listener, and I keep wanting her to give me more information in general. And that is more me than her she is responsive.
