From the beginning, no one clearly explained potential charges. There seems to be zero consistency in communication between staff and the doctor. I was told after the fact that I would be charged for services they assumed I "should have known" about even though no one ever mentioned them beforehand. I paid to have my 11-year-old son's serum overnight shipped, which was already an added expense. After that, there was no follow-up or confirmation that it was received. Instead, it was somehow sent back to another Allergy Partners location, and I had to go through the process of shipping it again. On top of that, I submitted school forms that were extremely important only to be told they were shredded. I had to go back to the school, get everything redone, and resubmit the paperwork. Then, unexpectedly, I was told I would be charged for the forms as well, which was never communicated upfront. This entire experience has been disorganized, stressful, and especially disappointing when you're dealing with a child's healthcare. Clear communication, basic organization, and empathy should be the standard and unfortunately, that has not been my experience here.

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.

They threatened us that we both have asthma and should keep visiting their office for more tests. After received a roughly $600 bill after insurance coverage, we gave up on this doctor and visited other doctor's, which turned out we are both very healthy:) We suspected that they might over-diagnose their patiences. I would not recommend you to go here because that is the worse experience I ever had.

TLDR: Dr. Rosenthal and his staff are everything I was looking for in a doctor/doctor's office -…read moreknowledgeable, not rushed, listens to patients, compassionate, and knows the prices of services ahead of time! It's rare that I walk out of a doctor's office wanting to tell everyone how great my experience is, but that's exactly how I felt! I immediately had a positive impression when I walked in while on a work phone call and the staff told me to take my time with my call. As I filled out forms, I was surprised to get a form that actually told me what my insurance covered - the amount of my deductible, the amount I had already met, and what percentage was covered for allergy testing/allergy shots (with CPT codes too). When I asked the cost for each allergy test prick, I was floored when she could actually tell me the cost - $12 a prick or $600 for all 75 pricks. I can't tell you how many times I've walked into a doctor's office and no one knew the cost of procedures or the CPT codes for the procedure. I couldn't believe it when Dr. Rosenthal spent around 30 minutes with me, in an era when most doctors are limited to 10 minutes per patient. He asked me about my allergy history and tailored his plan to what I said. When I said I didn't want to do allergy shots, he was willing to try an alternative to see if that would treat my problems. When I said I didn't want to pay $600 for all 75 allergy tests, he decided to limit the allergy tests to the ones with the most actionable plan for prevention. On top of all that, Dr. Rosenthal is older, so he's got a wealth of knowledge from first hand experience with patients. For example, he had heard of my very crazy MSG allergy and took the time to teach me how MSG affects the nervous system. He knows which allergy medicines tend to work better for most patients. I really can't say enough good things about Dr. Rosenthal and will recommend him to everyone who mentions allergies to me!

There is hardly any wait time, whether you are seeing the doctor or getting shots. Such a wonderful & responsive staff. Cannot recommend them enough!

Dr. Nsouli is a very kind, caring person, who comes across as someone who knows what he's doing without coming off as arrogant. I've had severe allergies all my life, and Dr. Nsouli is the fourth one I've seen over the past twenty years. He's definitely been one of the top two, mostly because he realized that one reason why I have trouble staying awake (something I thought was completely irrelevant but he asked about it anyway) was because the allergy medication I was currently taking made me sleepy. No other doctor I've seen ever made this connection. When you have to get refills on your allergy serum, you always meet up with a nurse practitioner, not Dr. Nsouli himself. I imagine this is standard protocol, since the good Dr.'s time is valuable and you're not going because of a problem, you just need a refill on meds.

His office and staff are extremely friendly, and efficient. I highly recommend him to anyone with similar issues.
