Going to the doctor, any doctor, is not a situation to which I look forward. However, my visit with Dr. Long was a very pleasant experience. His staff is gracious and professional. Appointments are honored. Dr. Long is thorough, caring (readthat, painless) and not an alarmist. I very much liked his style and feel quite comfortable in his care. My condition will require follow-up visits, and I will be happy to return to Dr. Long's office.

He is thoroughly professional and courteous. My issue wasn't serious, but he was patient with me in explaining what it was and the treatment. Dr. Long gave me a medicine sample to take home, and I'm still using it. The conditionis slowly clearing up, and I'm satisfied with his clinical expertise. I would gladly recommend him to friends and family.

I dont appreciate them calling me and demanding a credit card to put on file before I even met the doctor or walked in the door. Then ehen I checked in, they asked for copay before I saw the doc. I'mnot huge on establishments that it make it more than obvious that they're only about the money.

This was my second visit with Dr. Long, and it was terrible. He did not listen at all to my skin concerns but rather trivialized them and provided no recommendations. I will not go back there.

First appointment was cancelled. OK, it happens. Second appointment: Cancelled 30 minutes before while I'm en route via subway. Salt in the wound: When I arrive in a bad mood and talk to the receptionist, a "manager" jumps into the conversationand starts smartmouthing me. Really nice. I'll find another practice, thank you.

I did not like this visit and it was my first time seeing this doctor. First, these offices make such a big emphasis on the patient to arrive 10-15 minutes earlier for paperwork (which I complied and ALSO completed through thisportal for expedite processing). I was waiting for almost 30 minutes before I was called into the room. The front desk lady who called me in can't even differentiate between Atripla and Truvada! Then the doctor walks in, spends 5 minutes checking my skin and puts on the wrong prescription order to my pharmacy!!! Absolutely preposterous!

I have gone to Dr. Long in the past based on a referral from my primary care physician. He was helpful then and helpful now. He clarified any questions I had and prescribed medication for what I needed. Since I onlycame in for a regular check up he told me I probably don't need to come in for another 3 years considering my age and overall health.

He was by far the rudest and more arrogant doctor I have ever been to. There's a reason why he's the only one with appointments available between now and January in that office. I came in with an itching problem andall he did was lecture me on why it was so difficult to diagnose and that all he could do was give me an antihistamine. He was a joke and total waste of time.

A lot of the reviews mention his bedside manner not being the best, but in my opinion you want your doctor to be smart and knowledgeable and not your best friend. He could use a little softening on the edges, butI am confident he knew what he was doing and took the correct steps to treat my issues. Definitely recommend as he seems like a very talented doctor.

Nice office, took me quickly, clean, efficient. Dr. Long is very nice although a bit uncomfortable around people. Nurse who brought me into the room asked me questions about why I was there but wouldn't wait for my reply, interrupting toanswer for me, which I didn't appreciate. Even if I am a totally average person with average problems I should be treated with interest by the health professionals.

I came to Dr. Long to get a second opinion and I am glad I trusted my gut instinct to do so. He gave me a different medical diagnosis and explained to me what my skin problem was (showing me pictures)and took the time to explain why the other doctor's diagnosis was incorrect. He prescribed me medication for a skin condition related to my pregnancy and took in my concerns for a mild hydrocortisone cream. He was professional, thoughtful, answered my questions and I feel quite positive about the entire experience! Will definitely be back!
