He is the best! I was an hour late officer had closed. He took us in even though our driver’s dispatcher notified our driver they had called the office to inform we were caught in traffic due to accident., only to find out that Dr never received the call. I forgot my phone so I couldn’t called to confirm. I would not ever change our GI!!! High recommend Dr Arimie and his wonderful staff!!!!
