My cardiologist recommended that I see Dr. Mark Rayman and I am thrilled to have him as a doctor. He and his beautiful wife have a real family like business in El Segundo but it is very high end from the fish tank to the coffee. Everyone working there makes you feel so comfortable. And Dr. Rayman loves what he does so much I think he’d bend over backward for any patient. Ya just feel like he’s a friend (that’s so knowledgeable). Awesome!!!
