Kind, caring, short wait time. Genuinely wants his patients to feel better & have good health, rather than rushing and over-treating as most doctors.

The Doctor was excellent, he was accompanied by a PA, the office was clean, and the wait time was minimal. I did have one problem however, the MA named Lisa didn't seem too happy to be at work today. She hada grimace on her face, didn't introduce herself, and I guess I asked her too many questions because she left me in the exam room before completing the "assessment", and another MA came in to finish it?? how rude and unprofessional! I only know her name because I asked her for it, no ID's are worn here otherwise, my visit was a good one.

Dr. Nassim's office is the exact opposite - he was very friendly, personable, and thorough. We discussed the reasoning for my visit and he explained everything to me very clearly. The office is clean and all of the staff are very professional. I will definitely be returning.

Dr. Ariel is a good doctor he runs a family practice which is nice. His medical assistant Lisa is very professional and easy to talk to- I truly appreciated my time with her. My only issue with my appointment is thatI made it for 9:30 am and I had work at 2 pm; the office was not busy at all 4 patients max and I actually left at 12 pm so I had only 30 mins to get to midtown on time for work. Time management is key.

Wait time was lengthy to see the actual doctor and their system/computers were constantly down delaying everything. The receptionist at the front desk kept misspelling my last name on all the documents and in their system. But seem like nicepeople. Hopefully my next appointment will be a lot smoother if there's ever a need. The doctor was great once I actually got to see him and very personable and pleasant.

Dr. Nassim is professional, engaging, and knowledgeable. He structures the visit around the patient, which I appreciated. His Sports Medicine background was also helpful in evaluating a minor injury I had. However, the overall visit wasa bit disorganized - longer than needed wait in the front office, especially since there was only one other patient besides me. I was asked to fill out a full form about medical history and then was asked the same exact questions again by the medical assistant in the exam room, who was documenting it in the record (probably can skip the first step of paper form). In total, though I showed up for the visit on time, I was in the office for 90 minutes (only 30 mins of that was probably an active part of the visit), which I think was too long.

Dr. listened patiently to my problem and history and his treatment addressed my immediate concern. I started feeling better the same day. Additionally, Dr. Nassim recommended a follow-up, at which time he presented a logical and thoroughplan for diagnosing the cause(s) in order to prevent this issue from reoccurring. Doctor has a very gentle and compassionate bedside manner and everyone on his staff is friendly, professional and helpful.
