Patient Reviews
Jan 12, 2024
Dr. Gahagab has been been incredible regarding an issue that I have been dealing with for almost a year. It’s a complex situation to treat, and I had to have three surgeries but I finally see the light at the end of the tunnel. His care is impeccable. He is thorough with his communications and a caring and sensitive clinician. I am beyond grateful to have been referred to him and would highly recommend him to others.
