I generally wouldn't recommend selecting your medical professionals based on Yelp reviews, but for those that insist on doing so, I've had nothing but good experiences with Dr. Olstad going back several years. He's efficient and friendly, and his staff knows what they're doing. Now, I only go to him for basic dermatology, but I have complete confidence in him for that.

His practice is not cheap; if what you're doing is elective, then I can't believe you'd be surprised that a doctor on the Upper East Side was expensive.

My appointment today was for 2:40pm; I arrived five-ten minutes early and I walked out the door at 3pm.

I've been going to Dr. Ostad for quite a few years, I had to stop seeing him due to a change in my health insurance for a brief period which was sad. But now he is on my insurance again.

The receptionists are all super sweet and it's a smooth appointment making process. Dr. O is always on time and does a full body check- he is super through and always takes a sample of any irregular moles or marks that look suspicious. I have to go every 6 months for skin checks because of my many years of visiting tanning beds.

I also had a broken skin vessel (vein) on my face and he lasered it off two years ago, I was super happy with the results with that too.

I am a 60 year old that looks 10 years younger except for my forehead. I have those scowl lines that do not disappear no matter how much make-up filler you apply. I went to Dr. Ariel Ostad's office and was greatly pleased with my results. I know longer need to cover my forehead with bangs and side sweeping hairdos. The Staff and Dr Ariel provided professional and caring service. The reception staff are very pleasant and accommodating . I will be back time and time again. Thank you

I went to Dr Ostad for a full body checkup last week and my experience was exceptionary. Upon arrival I completed the paperwork and got called within 5 minutes which is unusual.

He appeared very sociable, highly informed and during the checkup he really took the time to discuss my health and preventionary measures which I appreciated. Following the visit both he personally and the staff followed up with me several times both over the phone and by email. I've lived in NYC for 15 years and have seen a lot of doctors and this was truly one of my best experiences
