    She was wonderful and I am super picky on the physicians I feel comfortable seeing! She was kind, empathetic and addressed all my questions! Before I left the clinic, I had referred two of my family members to see her as I had a wonderful experience. Felt she was a great patient advocate!

  • Apr 9, 2024

    Very kind and respectful. I appreciated the way Dr.Sunday treated me when I was feeling very anxious about the appointment.

  • Apr 4, 2024

    I was very pleased with Dr Sunday and the nurse who checked me in and did vitals was very kind and pleasant
