    The receptionist may be friendly but the nurses are not trained. The new nurse asked if my relative…read moreknew what she was given and the dosage. The nurse reviewed my relative's charts and still gave her the wrong dosage. My relative is given a diluted dosage due to adverse reactions. So her arm swelled to the point where her skin was stretched and painful and the swelling spread past the elbow halfway up the forearm and also caused a weird discoloration/bruise. The receptionist called us a week later letting us know this was a mistake made by the nurse and that Dr. Ahmad Hamad would be able to talk to us during our next visit in two weeks. IF this doctor had any sincerity he would have called us personally or at least let his receptionist know to apologize to the patient. This happened while we were on vacation which ruined our trip and caused us to cancel our non-refundable activities. We will not be returning. I would like to offer more photos as an example but unfortunately didn't not take anymore since we were focused on trying to reduce it and stop the spreading. But, a photo has been attached to show the swelling past the elbow, the redness that accompanied it, as well as a halfway swollen forearm. When you compare the injection site to the area closer to the wrist in the picture, you can tell how swollen her arm became.

    Dr. Hamad helped get a severe asthma flare-up that happened after I replaced allergy shots with…read moresublingual allergy drops (huge failed experiment). He reviewed my allergy tests and told me that I had too many allergies for drops to be effective. He helped me get the asthma under control and quickly restart shots. If you have to do allergy shots, I can't rave enough about this office. They have very generous shot hours, are willing to do what it takes to keep them on track, and have great hospitality. When I got shots before, I usually had to take time off of work because they had such limited shot hours -- which is why I switched to drops in the first place. They have much longer shot hours and it makes a huge difference.

    I have used various dermatologists through the years but Maria Bertagnolli at Georgetown…read moreDermatology is in a league of her own. She is knowledgeable, and conscientious, and takes her time to make sure everything is seen. Often dermatologists quickly go over your body and don't talk about what they see. Maria takes her time and describes everything she sees so that you have confidence that nothing has been missed, even that dangerous looking dark spot that you were sure was cancer and that she identifies as just extra melanin that is normal even before you can ask her.

    I have been a patient and customer at this office, but my recent experience at the front desk was…read morevery disappointing. I stopped in to purchase a lotion, and the front desk employee with dark hair looked me up and down in a way that made me feel unwelcome, as if I was inconveniencing her. Her attitude throughout the interaction felt dismissive and unprofessional. When I later expressed my dissatisfaction to another front desk employee/cashier with grey hair, she also responded with an abrupt and defensive tone instead of trying to address my concerns. As I see other people have left same reviews . I do want to say that Maria Bertangolli has been amazing. She has always treated me with kindness and professionalism, addressed all of my concerns, and helped resolve my skin issues. She is the reason I continue to come to this practice, and I truly appreciate the excellent care she provided.
