Today was my first visit. The staff and doctor were welcoming and pleasant. The doctor was interested in me, my health, and what he could do to help me. They accept my daughter's and granddaughter's health insurance so we are schedulingappointments for them as well. I had a very good experience my first visit and appreciate it more than they know.

The doctor I have is excellent, caring and listen, professional. I wouldn't have know other doctor. He is good with his patients, he listens to what you have say. He checks you out he talks to you. He will see youknow matter how long it takes, not for one minute and you gone he is not that kind of doctor. I been going there for 2 or 3 years and couldn't ask for a better doctor.

As a 1st patient I was very impressed with all of the office staff I encountered from the front desk employee to Jen. The doctor has excellent bedside manner and was very courteous and pleasant. It’s ALWAYS good to have adoctor who listens to you versus hears you. I’m very happy with the staff and have told my sister about this practice as she needs to see a pulmonologist.

My visit with Dr Nwadiuko was an answered prayer after being discharged from Cedars Sinai Hospital in Los Angeles, California and returning home to Washington, DC. I appreciate the care and attention I received and I will be followed with allergy injections for long term care.

After the nurse recorded the results of the test, it was another 40 min before Dr. Nwadiuko came back to look at my arms himself. I didn't want to scratch the test areas so that it would still be accurate whenhe saw them, but that meant I spent a total of an hour with excruciatingly itchy arms, and not able to touch them. Other than the wait time, the experience was fine.

Have only gone for the initial visit and was sent for an X-Ray. Am going for a Cat scan tomorrow. So far so good, but I have to wait to see how/if I am cured before I give all Excellents.I was seen after the appt time but had to fill out a long questionnaire first. Therefore I could say I was seen 'right away' OR in '[30 min. or less'. You may change answer at your discretion.

He’s very sweet, caring and he has an overall genuine concern for his patients. I’m dealing with a health issue outside of his practice area and seeing me in pain he was concerned. He asked what doctor was treating me, whenwas the last time I saw them, and he inquired about the medications they had me on. Seeing how concerned he was really put a smile on my face because you don’t find that quite often. Most doctor’s just treat you and send you on your way, if it’s not their practice area they could care less.

My son has had a couple of appointments with this doctor. I am extremely disappointed on how we were treated and the inconsistencies in the information he provided. When asked questions, he seemed to get upset. The doctor spoke to meusing medical terminology. However, as I explained to him, I do not have a medical background. At that point, he began speaking to me as if he was speaking to a child, which was insulting and degrading. We were treated awful. I wasted my time and co-payments going to this doctor. I walked away with NO clarity and NO real answers. Every statement he made was a contradiction of the previous statement. At one point doing this appointment, I was asking a question and he cut me off mid-question to make a phone call. He never answered the question. Few minutes later, he says to me "Good luck to you." My son was in tears. Again, we were treated AWFUL!!!

They didn't call to confirm my appointment; I arrived in time for a 2:30 appointment and was told it was actually 3:30. But the staff were kind. I went out on an errand and came back and they picked up withthe registration process without a hitch. Because the first staff member had to step away from the desk after I gave her my id and insurance card before going to the bathroom, she made sure to tell me who would have them when I returned to the desk. That staff member made sure to look carefully at my photo and then at me before handing the cards over. I haven't seen the doctor in 16 years so I was astonished that he remembered me. He even accused me of having the same pair of glasses LOL! Dr. Nwadiuko has a congenial but businesslike personality. There is a good rapport between he and his staff and between the staff. They were thorough, making sure I had everything I needed before I left and knew next steps.

Dr. Nwadiuko explained my asthma condition and how it has affected me and also used a set of pictures to explain what happens to my airway, with and without medication. After my skin testing, the Doctor reviewed the results of mytests. The technician shared important information with me and had me sign important forms, and scheduled me for my first set of allergy injections. Dr. Nwadiuko and the technician were highly professional, worked well together, and had a great sense of humor. This really helped since I had to endure the 70 intradermal injections:))
