Not only are his professional and personal manners a model of what and how a Doctor should be, he is an extremely knowledgeable technician in his field. He was prepared to speak with me by reviewing my past and current medical data. He offered guidance and ensured that all my issues were addressed during the tele-call. He offered to spend time to guide me through some rather technical aspects of setting up a complex medical device. Also, at the conclusion of the meeting he made sure that he understood what documentation I needed (which are written prescriptions) for both the medical CPAP device and future supplies for the device. He immediately at the conclusion of our tele-call sent a supplemental message with attachments of the prescriptions via Patient Gateway.
