    Mia Williams is my favorite doctor to see. She even noticed that I needed a moment before sending the nurse back in for checkout because I was feeling overwhelmed. She's so kind.

    Dr Williams has been outstanding with her care for me. She goes above and beyond to make sure I receive the help I need. She consults with my rheumatologist, does additional research, and above all listens patiently to figure out what needs attention. I truly feel blessed to have her as my primary.

    Dr. Williams is the best doctor I've ever had. Seeing her is a pleasure and I know she's improving my quality of life and longevity.To have a doctor who doesn't just say "lose weight" and leave it at that is a revelation. Her knowledge is deep, wide, and current, her compassion obvious, and she talks to me at my level. I'm inspired to take better care of myself every time I see her.
