Discovered a problem brewing with my cardiot artery which probably saved me from a stroke! Always on time and answers all questions. Personable. Have been a long time patient. MP
Woodmere, NY |
I had gone to Dr. Marshall on a Mon. after feeling flu like symptoms on Sun. Said I had a flu virus and was not eligible for Tamiflu which should only be given in the first 48 hours of symptoms. I was so why he didn't prescribe is beyond me. Went home laid in bed for 4 days with persistent cough, aches, fever that didn't get better. Sat. morning called office to see him refused to give me an appointment. Used receptionist as intermediary to try to schedule appt. dr. said he had no time to see me
Benn seeing him over 15 years
