He is the best! Such a great “bedside manner”, makes you feel like you are his only patient. He listens to you & is fully aware of your file/history! Does not rush the appointment time. God bless him, he is very special!

In my initial meeting with him, he had already looked at my chart. He knew I had pulmonary embolism several years ago. So he recommended a different drug because of this. He made me feel cared for.

I had a wonderful visit with Dr. Granger. The office was clean, my appointment was on time, and he was thorough, kind, and easy to talk to. I also appreciated that he asked my permission before using AI to document our visit. Dr. Granger and his medical assistant, Jenna, have supported me throughout my cancer journey with exceptional compassion and care. Their kindness and genuine concern have made a difficult experience feel more manageable. I’m truly grateful to have them on my care team and couldn’t ask for better support.
