What an amazing doctor and staff. He treats you as if you are the only patient he has to attend to. He will spend whatever time with you to ensure you are comfortable with the procedure he will be doing. Thank you, Dr. Galvan, for being so kind and compassionate to me before and after my surgical procedure.

Dr. George Galvan was well prepared for the initial visit.
The morning of the surgery everyone at the Stone Oak Methodist Hospital was very professional and still concerned that I was comfortable. I could not expect to have expected better care by the hospital staff on the surgical floor. Praise the Lord!
