He is an awful doctor. all about money he careless for your health, your wellbeing. asking him to send a lab work order. He charges you for just sending lab work. I confront him he blocked my patient portal and behaved in an unprofessional manner and very rude please stay far far away from this doctor and all of the doctors in this Maryland Endocrine office. all staffs are extremely rude, nasty, horrible, hostile, aggressive and talking over you and cut you off while you are talking. the entire office from top to bottom and I guess it is the nature of this office. The office manager even the nightmare to the patient.

Of all the doctors I have I feel he is the most caring. When I was down on my luck he gave me free samples and also discounted my price to make sure I could be seen. I truly respect him as a patient and would recommend him to anyone asking for a top notch endocrinologist.

Great Doctor, he is honest, but doesn't hit you with a bag of hammers. Asks questions about you, your environment, changes to routine, etc.; not just the standard , "How you feeling?" Staff a little slow on processing prescription refill requests from pharmacy (seems you have to refax 3 or 4 times and personally follow up with a phone call), but overall a good group.

Dr. Argento is an outstanding specialist. He spent as much time as necessary during my appointment(s) in order to make an accurate diagnosis. He helped solve an issue in short order that has been bugging me for over a year.
