I stopped going to Dr Darian. He seems competent at first but not very friendly with broken English. Very cramped office. Nice hygienests and dental assistant, and window receptionist. I was in the chair about to have a filling done and he would not work on me because I was on Coumadin. My hematologist told me no one should go off their coumadin for normal dental work. Darian had to have this in writing before he worked on me and did not have time for me to call hematologist and have them fax something. He knew that I took that medication prior to this yet allowed staff to make this filling appt. for me. I found another dentist who already knew that patients need not go off their coumadin for dental treatment AND he did not find a cavity where Dr. Darian had planned to fill! Very strange indeed.
