Mohamed Faris, MD

I am one of the core faculty at the Internal Medicine Program at Grand Strand Medical Center. Having graduated from that very same residency program, the decision to stay was one of the easiest decisions I've ever had to make. If you ever visit Myrtle Beach you'll understand why. I graduated from Ain Shams University School of Medicine in Cairo and did 2 years of dermatology residency at that same university before moving to the US. I enjoy travelling the world as often as I can, playing and watching soccer, and learning the piano.
